POSP for SKS... 4x or 6x?

[Andreas]

Good Day,

I am planning to mount a POSP scope on my SKS to make a pseudo DMR rifle by putting it in a Dragunov style stock with a bipod. *Disclaimer: I know the SKS is not known for it's accuracy... but the one I have groups surprisingly well using iron sights at 50 and 75 meters, so I thought it might be fun to put a scope on and the POSP seems most appropriate (it looks cool, has a wicked reticle, and is not too expensive).

I have done some reading on the POSP scopes and cannot decide if I should get it in 4x or 6x.

From what I have read the differences are as follows (and please feel free to correct and/or supplement this info):

4x POSP
- comes in both the 400m Simonov calibrated reticle (for 7.62x39), and the 1000m Dragunov calibrated reticle (for 7.62x54R)
- wider field of view when looking down the sight
- is narrow enough that I shouldn't need a casing deflector to protect the scope
- seems to me more appropriate for the 7.62x39 as I'm not going to be shooting more than a few hundred meters
- has a slightly different reticle with only 2 chevrons for bullet drop *this is where the confusion lies*

6x POSP
- comes in only 1000m Dragunov (calibrated for 7.62x54R)
- more powerful sight but narrower field of view
- slightly wider so I'm not sure if ejected casings will clear the scope. Can anyone clarify this?
- seems more suited to a rifle in 7.62x54R (ie. SVT-40/SVD)
- also has various combinations of reticle/rangefinder


*I seem to come across different reticles/rangefinder layouts with the 4x scope... some based on a 1.7m target, some on both a 1.7m and 0.5m, some with 2 chevrons for holdover, and some with 4 chevrons. I can't seem to get it straight which ones come with what combination...

So what are everyone's thoughts on this scope? On 4x vs 6x? What are your recommendations?

Thanks for all your input

I have a 4x Vomz with 7.62x39 BDC reticule on my SKS and it works quite well. My main point of advice would be to not cheap out on the mount and either have the side of the receiver drilled and tapped for a side mount or use a Magwedge/Wartak rail.

 

[warrenlikesboats]

The accuracy in the information one finds about POSP's on the internet is ALL OVER THE PLACE If your ordering "POSP's" from Westrifle, I believe they are ALL 54r ranging reticles and they are actually NPZ PO's ; and PO's are a civilian version of the PSO's, which means the rangefinders on them are all calibrated for a target of 1.5m. If you are ordering from Eastwave... they have all the specs listed for the scopes, but before ordering, id email them confirming that the scope has exactly the features your looking for. Also be aware that their prices are USD, and they import the scope for you straight from the Belarus factory which means there is a decent shipping fee.

Given the choice, id go with the 6x unless the size of the scope on your SKS is a big deal for you. With a 4x, there may be situations where you wish you had alittle more magnification to make out that target better... where with a 6x, you have the extra magnification, but if your in the bush and need a close range sight, you can simply slide the 6x off in about 4 seconds and just use the irons on your SKS.. OR just leave the 6x power on and lower your cheek weld and use the SKS irons that are unobstructed by the scope.

The ranging part of these scopes works regardless of what caliber you pair them with. You will still be able to range a target with a 1000m 54r reticle on an SKS, And I personally never shoot my SKS far enough for the chevrons to really come into play anyways.

 

[warrenlikesboats]

Plus depending slightly on the side mount you choose ,, these scopes hang out to the left far enough that ejected casings shouldnt hit the scope. But if you have access to a dremel, id recommend dremeling out the ejection window on your SKS (featured in one of the stickys in this forum) . I recently did this to mine and it seems to work great, I have a PO 3-9x24 hanging over the bolt and none of the casings hit the scope.

Thanks guys for your input! I'm kind of torn... I really like the idea of having a reticle calibrated for bullet drop in 7.62x39, but I do like the extra magnification and the fact that the range finder obviously works with any rifle. I hear that eye relief can be a bit of a problem with the 4x scopes. Some report that you have to have your eye in precisely the right spot or the reticle is out of focus. The 6x42 scope has a diopter adjustment which will take care of this problem. So I'm stuck between the 4x24 Simonov 400m or the 6x42 Dragunov 1000m scopes.

 

[mchouvaev]

Both PO and POSP scopes were designed for civilian market and rangefinder based on 1.5m target. There is 6x24 and 6x42 models. 6x24 model has same dimensions as 4x24, 6x42 bit bigger and heavier. Also make sure you get appropriate side rail. Either one will be off centered (left side) so that helps a bit with ejected casings

 

[Beater]

ive put both on sks 6 is to much for the cartridge for just plinking and playing in my opinion

 

[warrenlikesboats]

I personally went with the variable zoom route, Ive got a 2.5-5x24 POSP with a 7.62x39 reticle on my VZ 58 (the 400m rangefinder is for 1m targets though) , I have PO 3-9x24 54r for my SKS, and I bought a fixed PO 6x36 54r for my SVT 40 just because the scope looked good and the is gun really only for show (dosent need to adapt for different environments)

The variable zoom scopes give you the best of both worlds...

Ive got a 2.5-5x24 POSP with a 7.62x39 reticle on my VZ 58 (the 400m rangefinder is for 1m targets though) ,

I have PO 3-9x24 54r for my SKS

WarrenIsTheMAN(AndAlsoLikesBoats)

1) Can you please take pics for both of these on a VZ58?

2) What rail is required to mount either to a VZ58 Sporter?

3) I see Eastwave has a POSP 2-6x24... isn't that the best of both worlds? I think I might lean that way... thoughts?

4) What is the real difference between reticles?

POSP 2.5-5x24

POSP 2-6x24

4) Do the above 3 mentioned varible magnification scopes all have a Diopiter Adjustment? Does this help with eye relief?

5) I'm a little concerned that my VZ58 tosses brass vertically a lot, I understand these sit slightly to the left? Helpful to know how much each optic sits in front of the ejection port

Whatever I buy is gonna end up on the fixed stock configuration below...

Good thing its a rainy day where I live lol So,

2) All of the SVD style POSP's (like the 2-6x24 you pictured above; SVD style purely has to do with the type of mounting clamp on the bottom of the scope) can ONLY mount on an SVD style mount (so dont buy an AK mount). Mounting an SVD mount to your VZ is most likely going to involve drilling holes in the receiver of your gun and possibly tapping them.

West rifle sells a very good SVD style mount for the 858/58 (the one I have equipped on my CSA) http://westrifle.com/wrstore/index.php?main_page=product_info&cPath=15&products_id=804

This mount will allow the POSP to slide forward far enough to allow proper cheek weld (unlike the very popular CZ factory one that people simply screw into their CSA's) It also comes with 2 5m hex head screws and the 2 holes in the mount already drilled and tapped for 5m. SO if you own a 858 or a old 58, you simply place the mount on the receiver, mark the holes, and drill them through the receiver with a 5m bit. On a CSA, things get trickier. The area in the front where they intend you to drill the first hole is not accessible from inside the receiver. BUT you can utilize the 5m hole in the area already drilled for the CSA factory mount. This means you will have to purchase a 5m countersunk head bolt and drill out the treads in the front hole of the SVD mount and countersink it to allow the POSP to slide over the bold head. The rear hole is drilled no differently than the 858's/old 58s. Sounds like a alot of work, but it really only takes a hacksaw, drill press, assorted drill bits, a dremel and a few hours of your time.

Cant remember if you said yours was a CSA, but I typed that out anyways encase some other CGN user wants to know that in the future.

3) i was going to buy that scope, but decided to go with the 2.5-5 instead because it comes with a 7.62x39 reticle, and i want to feature that reticle in one of my utube videos in the future. in the same size package of a standard POSP, you'll have 2 power for close range, and 6 for bench shooting...i would consider it the best of both worlds.

4) the 2.5 is a 7.62x39 reticle, calibrated for targets of only **** 1m ***oddly (unlike the picture)
the 2-6 is a standard 54r SVD reticle, calibrated for targets either 1.5 or 1.7m (and they often feature a .5m target built in for crouching enemy's) (1.5 or 1.7 you'll have to ask Eastwave which it is)

5) not that i know of, youd have to buy the design specific Diopiter (-D) series on Eastwaves website to get that feature.... i have no experience with those scopes.

6) i havent shot my CSA with the POSP on it yet, but i presume the ejected brass will pose an issue. for me, because in building an AKM clone, im going to integrate a shell deflector into the dustc over; that at the same time makes it look more AKM like. But for you, since you dont want to modify the gun very much i presume. You may have to cut a nice little deflector out of light tin or aluminum, and bolt it to your POSP (using bolts already located on the POSP) OR simply sliding the deflector under the SVD mount when you bolt it to the gun like other CGN users have.

time for pictures...

[warrenlikesboats]

The 2-6x24 will look smaller on your vz, it will offer a much more comfortable cheek weld with the short vz stock, it comes with a flip up objective cover. The 3-9x24 will look larger, have a slightly uncomfortable cheek weld, have a nicer finish, takes AA batterys instead of watch battery like 2-6, it comes with a much more comfier and discrete rubber eyepiece, fast shipping, a slide-able sun visor, a crappy objective cover and will be cheaper price wise (scope is same quality if not better).

The 3-9 came in a NPZ factory box, professionally wrapped and with a SVD rail for your SKS or SVT.
The 2-6 will come from Belarus in a camo POSP cover, bubble wrapped lol but you can use the cover to protect your scope later on!

The VZ military stocks really were made for iron use only... they offer a fairly poor cheek weld for any type of scope...for your VZ id recommend seeing if you can build a rubber buttpad as an extension first, instead of spending your money in that stock extender. Ive tried both scopes and they both kind of warrant a extra inch in the configuration seen in the above pictures. Id also consider some sort of cheek riser that you can strap onto your buttstock like what the M1a guys all use.

best of luck!

Yup mine are both 2014 CSA VZ58 sporter rifles... Geeze that does sound like a lot of work but well within my skill level...

Seems to me you're gonna need to tap that front hole you drill in the receiver? Wouldn't it be easier and cleaner to drill a hole in the receiver at the most forward accessible point inside the receiver a bolt can be tightened from within, drill another hole in the mount and tap the mount for the provided M5 screw? I don't imagine the receiver being exactly easy to tap?

3) decided to go with the 2.5-5 instead because it comes with a 7.62x39 reticle...

What exactly makes that one a 7.62 reticle in comparison to the other reticle? Sorry I am new to this calibre's ballistic considerations in regards to optics.

I would consider it the best of both worlds.

To be clear, the 2-6x24 POSP in your opinion is the best of both worlds? (Kinda how I feel about it...)

4) the 2.5 is a 7.62x39 reticle, calibrated for targets of only **** 1m ***oddly (unlike the picture)

Meaning it doesn't have a 'man size' range finder... is that all you mean?

the 2-6 is a standard 54r SVD reticle, calibrated for targets either 1.5 or 1.7m (and they often feature a .5m target built in for crouching enemy's) (1.5 or 1.7 you'll have to ask Eastwave which it is)

AKA 'man size'...

LOL this consideration for Eastern Block civilians reminds me of OUR government and OUR silly laws!

5) not that i know of, youd have to buy the design specific Diopiter (-D) series on Eastwaves website to get that feature.... i have no experience with those scopes.

Hmmm yet some of the scopes you own list a diaopter adjustment

EastWave POSP 2-6x24 = Diopiter Adjustment +/- 2
WestRifle POSP 3-9X24 = Diopter adjustment, -0,5 to -1

typically this is for people that wear glasses (which I do not) but I figured it may help with focus and long eye relief?

6) i havent shot my CSA with the POSP on it yet, but i presume the ejected brass will pose an issue. for me, because in building an AKM clone, im going to integrate a shell deflector into the dustc over; that at the same time makes it look more AKM like.

This would be my, and I imagine most people's, biggest consideration... are there any threads on this procedure out there for building the ultimate brass deflector for this mount? Where are the using bolts already located on the POSP?

How far the scopes hang off the left of the gun

Perfect! Still use the Irons no problem!

The SVD side plate mount

Did you mod the rear of that mount as well? looks like machining or grinding marks? I totally see how this all comes together now and am incredibly greatful for how much effort you put into this post...

well done sir!

 

[cement head]

I have shot the 3x9 posp on an sks and it was sweet . very accurate. I was at a range and tried one out . it was mounted to the side of the reciever which was drilled and tapped .

You will understand it better when you receive the mount, for a CSA no threading will be required. You have to purchase a countersunk 5m bolt, countersink and drill out the threads slightly on the front hole of the mount so you can push the countersink bolt through and screw that bolt into the pre existing 5m hole already on the CSA receiver.

The 7.62x39 reticle has 100m,200m,300m hold overs for that caliper. Also a 400m rangefinder for people 1.7m, or deer or some animal 1.5m (there is a never ending argument on the internet about what the 1.5m is for) or 1m, which is what mine came with.
The 7.62x54r reticle has hold overs for 54r, and 1000m rangefinders for either 1.7m or 1.5m, and usually a .5m for crouching people (thats the 2 arcs you see on the grid).

Im fairly sure they dont have a diopiter. Youd have to buy a POSP-D to get that. I have had no focusing problems with any of my scopes... you dont use glasses so you should be fine.

There is a Canadian on utube you has a shell deflector bolted to his posp using the bolts that connect the scope to the SVD clamp https://www.youtube.com/watch?v=Vxd7aXejhtg seen in this video.
Ive seen other CGN's mount a deflector to the SVD mount on the gun.

Thanks so much for all this information, very helpful!

From what I can tell this is what he is referring to as a shell deflector... did this come with the scope? Not really what I was thinking of, I was concerned with the bottom of the exposed tube above the ejection path, this seems to mount on the left side of the optic? A little confused now... its hard to tell but is there a bend at the top and a piece of metal protecting the bottom of the tube?

I have no experience with them... but I see many other CGN users have them mounted on their SKS rifles.
