New plastic tank 7.62 x39 from PTG
13.07.2012 16:33
Clear plastic trays of 7.62 x 39 mm for the GA. 58th .. from A to Z. ..

The performance of our plastic containers for the project site GUNEXPERTU, I totally saturated with ads ...

So I decided to write this short article and try to answer your questions so that we can save each other time and meet unanswered.

When I started buying accessories for their first 58-info be retrieved (all possible regardless of quality) and their subsequent resale at a loss (many know about it) discovered the "problem" which replace the original cartridge. Compared to such a range of AK 47 or AR 15 was no choice ... In addition to various truncated and spliced ​​conventional aluminum containers and exceptional 40 wound steel for RPK and 75 wound drums of "production" Gunexpertu was nothing on the market.

I made the "remakes" transparent containers from Promag. After about the first five destroyed tanks "work" on declared and transported from the USA came to the result. Some people have been through Gunexpertu enthusiastic when he bought the magazine from me - thanks for the support, I may be many angry when I wrote them a price. Thus I suggest you try it in order: to invent, test and produce 4-5 pieces which eventually discarded, and then finally make something functional, which will last for some the wound ...

But it's still not it. Without the shooting stand ... for example ... So I was after hours of interviews with rakeŤákom Fidom and decided to try, even if at the beginning of a healthy skepticism that still persists. Luckily I found someone who I can read your mind and on that basis, and about 20 different bins, which we bought, put my ideas reality.

I will help you a little earlier article, we got together with Fidom, so you can see at least in brief, what if we passed what we have come to understand. At the outset, perhaps the only technical issues I will ask all professionals and experts, may be released. I never had the opportunity to use the GA. 58 as service weapons and I am not educated anything at least from a distance resembled weaponry, or engineering.

Tray perceive as limiting of the weapons, which, if functioning as a whole is managed by design - is influenced by factors such as environment, service, quality ammunition etc.

Shape magazine is the shape of the charge of 7.62 x 39 mm. That way, shape tray and mounting in arms, raises a number of "problem" if you want to place such podpažbie. tactical vertical grip, when you find a good compromise between the point of its deployment and to secure and return the same container. No longer as a grenade. We found that with the do nothing. Magazine, we tried "straighten". We produced moderately curved prototype using slightly modified from the original feeder tray, but the magazine did not work as it should. We tried it with a brand new made-feed, but the result was the same. There have been several failures to convince us that the primary function of the reservoir (safely and reliably charge filed), is chief, as all tactical grips and grenade launchers together.

The original material container is relatively resistant aluminum alloy. Who ever tried to make a short stack and fit the bottom, so as to wound the original 30, I can certainly zapravdu that bend easily breaks (unless nenahreje, of course). My next experience with aluminum trays is that if the normal use wear the top part that fits into the arms to swing trays. This is understandable, since coming to the interaction of hard and soft material. It can be temporarily addressed oteruodolnou spraying of paint.
advantage of "soft" storage is that if the weapon falls on hard surface on the container is less risk of damage to the weapon itself, as in the arms of steel drums. Against this background plays an important role in the selection of plastic container production. It must be just strong enough, flexible, but also resistant to wear when interacting with the steel.

The surface of the tank to facilitate his grip while shooting, exchange, and in removing from the pouches. I hope that we have created a design that meets all these things. The tank is equipped with numerical indicators of the remaining munitions from both sides, which makes it easier readability Colored Feeder. Any "counters" was considered a complication of production (due to the shape of the tank) and a possible source of failure. This is not to say that the containers from other manufacturers of these devices are unreliable. We will just keep passwords proven that "simplicity is beauty ..."

"Pile" at the bottom of the container should facilitate the handling of the tank when removing from the pouches. The leader in this area is probably Magpul. When designing the floor with pull-type "Magpul" we again encountered the problem exchange tanks because of their shape, length, method of detecting the use of tactical weapons and accessories (handles). We decided to compromise by using flexible nylon webbing is strung in disguise for two of the tank. If this method does not suit someone, simply remove the belt.

"Connectors" on connecting an infinite number of bins next to each other - we finally abandoned by the whole number of reasons. In principle, we solved two ways. The first type was associated reservoirs HK G-36. We encountered the complicated handling trays for removing from the pouches (tanks to capture the "clutch" in pouches), we have verified also in discussion with professionals who prefer to use this weapon in the "soft tanks". The second way was the type of Sig Sauer, when the reservoirs connected by a plastic lantern. But the same problem arises as the HK G-36 tanks, plus there's another part that needs to be made ​​and you can very easily lose. In addition, two tanks connected to the hub 7.62 x 39 mm have a significantly different weight than tanks 5.56 x 45 mm, that is different is the handling of the weapon. Moreover, the available drum magazine for 75 rounds, RPK magazine for 40 rounds and 45 wound aluminum tray with shooting readiness. When we consulted on the possibility of combining storage with professionals prefer hot swap tray of pouches, before replacing the associated reservoirs, due to uncomfortable handling them in stressful situations.
But the "clutches" We have not abandoned altogether. We are working on external couplings, which are used in AK, M4/M16 or containers, whether from nylon, plastic, aluminum and steel. And finally, the type of mass storage segment Sure Fire are still in our PC ... a promising future as it currently looks like with them? Ongoing testing of prototypes. These "certified" and our own. We want at least a little closer to the traditions of Czech and Slovak master gunsmith. We want the magazine meets the most demanding criteria for "professional" but also "hobby" users. Tanks are manufactured in Slovakia and the Czech Republic. We did not go the way of cheap production far beyond. Price is therefore considerably higher compared to the original. But not unavailable because they are of course primarily intended for Czech and Slovak markets. Agreement with Gunexpertom, which will provide exclusive distribution in the Czech Republic is clear. Price will be published in those containers on the market. Time availability is around 4-5 months. We offer quality, not "rýchlokvasenú" quantity. Just stack, which is practical, beautiful and you have the feeling that the 58-cke just one. Nothing more, nothing less. And everything - tests, tuning prototypes, serial testing of products (materials, design, durability .... etc.) is worth something and it takes some time. Well ... and what you see in the pictures, the final version of a magazine photo of a prototype weapon.

Looks interesting, I've always thought the aluminum magazines were one of the weakest points with these rifles, hopefully they're decent.
 
Why do we need these? Whats the issue with the aluminum ones?

Just because, and also the aluminums are weak and "clattery" compared to AK mags and those of more recent design such as the PMAG and HK style polymers.
 
Weak? Really. Never had a problem with mine since I've been shooting. Yes they get dropped on the ground and stepped on, lost and found in the muskeg. Lighter then a AK mag (nice for us "old people"). I guess maybe we should ask Stevo. I know he puts his through the fires of Hades. Not trying to disrespect you sir. Just don't see the need. You can still buy them for 28.00 bucks and up in Canada if you have a bad one.

I have a CSA in .223 coming with the carbine length barrel and plastic mags. I guess I'll get to see how they stack up before I go the Lars 10rd mag route.

Those 2 piece body aluminum mags are one of the reasons the VZ58 platform never became more popular IMO. They just don't inspire confidence.

These make a lot more sense than most of the VZ58 aftermarket accessories now on the market, and would compilement the look of a tactical build well instead of taking the aluminums and repainting or anodizing them.

Polymer AK mags are lighter than the VZ aluminums and probably more durable than any other magazine design, these VZ58 poly mags appear to be thicker than their AK counterparts and could potentially be even stronger.

Anyways $28 is a lot of money to spend on a tinny aluminum mag that costs $13 in the U.S., I'd rather spend more and have something more modern and robust.
 
Why do we need these? Whats the issue with the aluminum ones?
What kind of ridiculous question is this, seriously? You expect there to be zero innovation with a popular commodity? I suppose we don't need any guns whatsoever, bow and arrow worked fine for millennia. :rolleyes:

If you need a reason, the aluminum ones are ugly. There.
 
Not sure if this is allowed...

Here are the pics though.

I like it :rockOn:
 
I like the metal ones better, to each his own. They're pinned to 5, so who cares... I'm on the fence about my HK USP mags that are a plastic polymer... I worry for their longevity.
 
I like the look of it.

I am in the market for a VZ58, these mags look nice to me.

What might pricing be like though?

I'm guessing they'll be at least as much as the $38 Vz58 polymer 5.56 mags, still, provided they're up to snuff, that's better than paying 2/3s as much for used or NoS {new old stock} surplus mags.

Anyway here's a less horrible Slovak translation;

New polymer mag for VZ58 7,62x39

The ABC of transparent plastic mags 7.62 x 39 mm for vz. 58...

Since introduction of our project on plastic mags at the website of Gunexpert my mailbox is full up...

Therefore, I decided to write this short article that should give answers to as many of your questions as possible, and explain any unclear issues, which saves your as well as my time.

After having started with purchase of accessories for my first Sa vz. 58 (which means any kind of accessory regardless of its quality), their subsequent sale and did not make any profit (a situation that is probably familiar to most of you), I found myself facing a “problem” as to what I can use as a replacement for the original mag. As opposed to the wide range of products for AK 47 or AR 15 my choice was rather limited: besides variously shortened and connected classic aluminium mags and excellent 40 round steel mags for RPK and 75 round drum magazine “produced” by Gunexpert, there was nothing at the market to chose from.

Then I developed and made “adaptations” of transparent Promag magazines. After I destroyed the first five mags that were “demandingly” transported from the USA and declared at customs, I achieved the first positive results. Some people, who bought this mag from me thanks to the promotion of Gunexpert, were genuinely impressed, and I would like to thank them for their support. Those people, who were obviously angry, when I told them the price, should follow the subsequent recommendation: first, think up something, then try to make four-five pieces that you throw away, and finally produce something that really works and holds some shots...

And yet it is not what you need e.g. without bolt catch function. After lengthy discussions with rakeŤák and Fido and despite healthy skepticism, that I still have, I decided to make a magazine from scratch. Fortunately, I found a man, who can read my thoughts. We bought about 20 various mags, and he managed to transform my ideas into reality.

At this point, I would like to use an older article that we wrote together with Fido, so that you have at least a rough idea of the outcomes and the long way we had to go. Before getting to technical issues I would like to ask all experts among you to be lenient. I have never had the possibility of using Sa vz. 58 as a service weapon and as far as my education is concerned my profession does not by far have anything in common with armament industry or engineering.

From my point of view, a mag is limiting part of the weapon, the functionality of which – supposing the weapon as a whole has a good construction – is influenced by factors like environment, handling, quality of ammunition etc.

The shape of a magazine is determined by shape of the 7.62 x 39 mm round. It is exactly the shape of the mag and the way it is fitted in the gun that lead to a lot of “problems”, when you want to fit e.g. a tactical vertical grip to a lower handguard, and have to find an acceptable compromise between the place where you put the grip on the one hand and a safe and secure change of the mag on the other hand, not to mention e.g. a grenade launcher. We found out that in this case we cannot do anything. We tried to “straighten” the mag. We made a type of mag that was not bent so much and used a slightly modified magazine follower from the original mag, but the narrower mag did not work properly. Then we tried to use a completely new magazine follower, but it was the same. Several defects that appeared convinced us that the primary function of the mag (i.e. to follow the round safely and securely) is more important than all tactical vertical grips and grenade launchers together.

The original mag is made of a relatively resistant aluminium alloy. Anybody who has ever tried to make a shorter mag and fix the bottom in a way it is fixed on the original 30 round mag will confirm the fact that this mag can easily be broken when you bend it (of course, unless it is heated). I can tell from my next experience of aluminium mags that the mags tend to wobble if the top part, which is fitted to the weapon, has worn out. This happens due to an interaction of soft and hard material and can temporarily be solved by spraying the mag with an abrasion-resistant colour.
The advantage of “aluminium soft” mags is that if the weapon falls to a hard ground, the risk of damage to the weapon itself is lower than in case of weapons with a steel mag. In view of these facts the type of plastic used for the production of mags plays a substantial role. The plastic has to be sufficiently strong and flexible but also wear-resistant in case of interaction with steel.

The mag surface has to provide for a safe grip when shooting, changing or pulling it out of the magazine pouch. I hope we managed to create a design that meets all of these criteria. On two sides of the mag there are counters showing the amount of ammunition available and a magazine follower of a different colour enhances legibility of the figures. In our opinion, any other “counters” would make the production more complicated (considering the magazine shape) and possibly lead to defects. However, I do not want to claim that magazines with counters from other producers do not function properly. We have just gone by the golden rule “keep it simple...”

“Tactical loops” at the bottom of the mag should facilitate the handling of the mag when pulling it out of the magazine pouch. The leading producer in this area is of course Magpul. When designing the bottom with a magazine follower from “Magpul”, we were confronted with the problem of changing the mags caused by their shape, length, way they were fitted to the weapon and use of the tactical vertical grip. We decided to make a compromise, and used a flexible cordura strip that is pulled through two integral loops at the bottom of the mag. If anybody does not like this solution, it is possible to remove this strip easily

As far as magazine clamps are concerned that make it possible to connect an unlimited number of mags – we finally rejected this idea for a couple of reasons. Basically, we considered two ways of connecting the mags. First, we tried to connect HK G-36 mags. The problem was that it was difficult to pull the magazine out of the pouch (the magazines got caught in the pouch clamps), which we verified in a discussion with professional soldiers that prefer using magazine without clamps in this type of weapon. Then, we tried to connect Sig Sauer mags by means of a plastic coupler. However, we found out that the same problem arises as in case of HK G-36 mag, and moreover, there is one more part to be produced that you can loose very easily. Furthermore, the weight of two connected mags with 7.62 x 39 mm rounds considerably differs from the weight of mags with 5.56 x 45 mm rounds, which means that the weapon requires different handling. Besides that, there is the 75 round drum magazine, RPK magazine for 40 rounds and a 45 round aluminium magazine with bolt catch function. When we discussed possible ways of connecting the mags with professional soldiers, they preferred a quick change of mag from the pouch to change of connected mags, because the latter were difficult to handle in stressful situation.
However, we did not dismiss the idea of clamps completely. We are working on external clamps as are used in AK or M4/M16 magazines and are made of nylon, plastic, aluminium or steel. And last but not least high capacity magazines like Sure Fire also have a promising future in our PCs...

And what is on at the moment? We are doing the “certified” as well as our own prototype tests, and we are trying to continue the tradition of Czech and Slovak craftsmen of armament industry a bit. Our aim is for the mag to meet even the strictest criteria of “professional” as well as “amateur” users. The mags are produced in Slovakia and the Czech Republic, we did not decide for a low-cost production deliberately. Therefore, their price will be higher than the price of original magazines. However, they remain affordable because they are primarily determined for the Czech and Slovak market. The agreement with Gunexpert, that will have the exclusive right to distribute the magazines in the Czech Republic, is clear. The price will be published on launching the magazine on the market, and the production time is four to five months. What we want to offer is top quality not quantity. It will be a magazine that is nice and practical as if it had ever been an integral part of your Sa vz. 58 - nothing more and nothing less. The whole production process – from testing, adjusting prototypes to testing mass-produced articles (with regard to their material, design, resistance etc.) needs money and time. What you can see in the following photos is final design of the mag and a photo of a working prototype fitted to the weapon.

I like them. The finish of my factory 858 mags aren't impressive at all. 2 of my 4 mags have some rough spots and overall they're not great.. I'd definitely consider these new magazines.
 
Wonder how they handle the cold temps we have up here.?

They should be alright, the Russian military have been issueing synthetic mags for nearly 50 years now, and the technology behind building a good polymer magazine is pretty well understood at this point.
 
Just letting you guys know, Czech and Slovak are different languages, they might be close but not the same. Not sure which language you translated...

Just different mags. Maybe if they made 10rd pistol mags I'd be interested...
 
I'd be in for 10 or 20 rounders, i have lots of 30 round metal ones that i have abused, and they just keep going.
 
czech Rep gets very cold aswell. What about russia's cold temps and their poly AK mags??????

What about the thermamolds the Canadian forces use to use??

Im sure they would be fine

I wouldn't mention those Thermold mags to anyone who was in the CF at the time and had to use the damned things!!!!:eek:
