I'm still having a lot of issues feeding rounds even after the modifications to the magazines :( The rounds keep catching on the sharp edge of the barrel coming into the reciever and smushing.

I think the magazine is an issue for the feeding problems but I think the biggest culprit to the feeding issues is that the transition from the receiver to the barrel is not tapered smooth so the barrel comes into the receiver with a sharp rather large ridge and if the plastic shotshell is not fed perfectly straight into the barrel chamber it hits the top or side of the barrels sharp edge and being plastic it just gets smushed into the sharp edge and then stops. If they tapered the start of the barrel to make it a smooth transition with no ridge or sharp edge for the shotshell to catch on THAT would solve the feeding issue I think much more then messing with the magazines. As it is its just any round not not fed perfectly centered into the barrel catches an edge so trying to make the magazines feed rounds perfectly centered is good but tapering the edge going into the barrel so its flush and smooth with nothing to catch would be a much better solution.

Any way to get that done ? Get the edge of the barrel tapered going into the chamber so there is nothing for the plastic shotshell to catch and grab

Same issue with mine. Shells keep getting stuck on that sharp edge and jamming. The edge is so sharp that it cuts a line through the plastic shel.

I'm seeing this with the 5 round mags, especially the less shiny extra mags I ordered.

With Uzkon 46 mags the problem is the angle of the shell in the mag is too low and it either fails to contact the bolt or smushs into the side of the magazine.
 
See the sticky at the top of our page: Alpharms 15 SA - Quirks and Tips:

Barrel Burr:
This is not a major issue, but I have seen it on two guns, Check the barrel chamber where she is machined for the extractor. You may find a burr at the end of the cut, you can feel it with your finger tip, A few strokes with a needle file will clean this up, or use a piece of fine emery paper on you finger tip. Do not use any kind of power tool like a Dremel as if you overdo this you will void the warranty.


Let me also add something else we just found out, with some shells the top of the brass base to the case is not "crimped" into the body of the case. "Crimp" is really an exaggeration but examine some different shell and you will see what I mean. If not really smooth these will aggravate any feeding problem.

We have also learnt that when the mag is a very tight fit in the mag well they don't feed as well as when the mag fits looser. Also obviously don't ride the bolt forward on the first rd and keep the action well lubed.
 
I don't even touch the charging handle on mine anymore. Load mag hit bolt release , good to go, reload mag , hit bolt release good to go. I lube the hell out of it right before shooting like John has mentioned and my mags and gun are broke in nicely after about 400-500 rounds. I have smoothed out any burrs or contact/rough spots with emery cloth when I have it stripped to clean. Runs like a champ now. Mine likes the score target loads 1 and 1 1/8 weight.
 
Mine will feed a mag then jam twice on the next then run flawless for 2 more .. same issue on all the mags. Tried some winchester #6 and i found the plastic to be harder than challanger shells. Still the same thing. Remington #6 same thing.. the doubble feed issue i have once in a while might be caused by short brass and the crimp issue wolverine said. On a diferent note the 01sa i bought is ausom .
 
If anyone is looking for accesories tooth and nail armory down in the states sells parts for a gun called the leader arms ar 12. Sometimes called pw arms ar 12 , pw arms is the importer down there. This gun just happens to be the same as the Alpharms . In fact leader arms is the parent company of Alpharms . Anyway they make an aluminum handgaurd with a side charging handle I just ordred one . Thinking about picking up there trigger aswell. They also have aluminum one piece handgaurds with optional top and bottom rails .

Let us know how that goes and post some pics an aluminum handguard would be a nice upgrade

I have bought a lower reciever and trigger group from them. Mat is excellent to deal with, part quality is excellent

My experience hasn't been positive, either... feeding issues, with all of the mags (I bought the gun with 4) and with all the ammo I've tried (at least 5 or 6 different kinds of ammo). Did the mag mods that were suggested - no change. At least one, if not more, misfeed per mag. I think I'm going to look at returning it. I REALLY wanted to like this gun, but I can't stand finicky firearms!

This is the problem I keep having:

I had mine out for the 1st time yesterday. Purchased 4 additional mags. Made the modifications as indicated. Loaded 5 rounds in the 5 magazines. 1 misfeed as the picture above shows per mag. Used new Federal 00B and Challenger bird shot. Same misfeed on round 2 or 3. I called them and was advised to use an emery cloth on the edge of the barrel where the misfeed occurs. Now I just have to get that damm bolt out from the end. Do love the firearm though, hoping that this will be solved real soon.

MKA 1919 Mags fit so do UZKON 10 rounders also but you have to pin those.

Would this not be analogous to the LAR magazine in AR and other STANAG rifles? That is the magazine is made to work in a pump action shotgun and it is irrelevant what firearm is subsequently used with it.

1. The Rock River Arms, LAR-15 Pistol qualifies as a "handgun, commonly available in Canada".

2. The cartridge magazine for this handgun as manufactured by C Products LLC has been deemed to be acceptable as a "handgun magazine" as it meets the following criterion:

a) It is designed and manufactured for use in a handgun commonly available in Canada and has a capacity of not more than ten cartridges of the kind or type for which the magazine was designed.
b) The cartridge magazine for this handgun as manufactured by C Products LLC is not an adaption of a magazine designed and manufactured for use in a semi-automatic rifle.

3. The design that has been found acceptable as a handgun magazine is held by the RCMP, Firearms Support Services, Firearms Reference Table Section as a "pattern". This particular design and NO other design is approved for use as a "handgun magazine for a handgun commonly available in Canada".

4. As an assist to identification, the cartridge magazines which have been deemed acceptable as a "a magazine for use in a handgun commonly available in Canada", bear the following identification markings on the body or magazine case, applied at the time of manufacture by the manufacturer:

The reality is the legislation specifies how to determine the capacity of a magazine... it does this by classifying the magazine itself for type and capacity based on what that magazine was "designed and manufactured" for. The legislation makes no reference to what firearm the magazine is subsequently used in once it has been classified and its' legal capacity determined.

The classification of, and the legal capacity of a magazine does not change simply because it is placed in or used in a handgun, a semi-auto rifle, a pump rifle, a bolt action rifle, etc..

You can buy a 30 mag pinned it's now a 5/30 legal mag. These shoot the same 12 ga ammo so if it's pinned don't see why there should be a problem. Obviously being a semi auto the 5 shot rule applies.
Unlike a bewoulf mag where it's built for different ammo all together yet are being filled with a different caliber. All I'm pointing out is that a lot of these Turkish parts are interchangeable same as flash hider/chokes.
Our laws are so confused and stupid that wouldn't say do it or don't do it. All I'm saying is it can be done.

You are right, you can have the UZkon 10 shot mags in a semi automatic shot gun WITHOUT pinning the mags. As long as the mag is legal it does not matter which firearm it goes into. Since there is no limit on a pump shoitgun and those mags were made legal by the RCMP for the that shotgun they were imported for
 
Just wanted to error on the legal side. I only wanted to point out they fit. Also they are not stamped at least the ones I saw. If your in the bush hopefully it won't be a issue.

Mine does the exact same thing, usually when picking up the first round if you use the bolt release (magazine spring mods have been done, Challenger and Federal target loads). If you "walk" the bolt forward instead it looks like the shell has more time to pop up and go completely horizontal, none of that nose up crap. Of course, when you fire off that round the next one tries to cycle very fast and then crushes the nose and usually cuts a strip out of the rim from the extractor notch too.

So far, not a firearm you would trust your life with. I would really like to get this to run for 3 gun matches.

Mine does the same. I had originally given the gun a rating of 6/10 dropping this to a 2/10 possibly the worst money I have ever spent on a gun. I have never bought a new or used gun that wouldn't run. this thing hasn't got 100 rounds through it. Did all the of the suggested mods and still does the same thing as above. I guess you get what you pay for. originally wanted it for IPSC. That unfortunately will never happen.
