plattner01 3 Posted November 1, 2012 Report Share Posted November 1, 2012 just took my poly choke off my saiga 12 and it fits my vepr 12 with no issues, so i think i will get another one for the vepr12 . if you guys find any other parts that fit post'em up Quote Link to post Share on other sites
hdskumm 39 Posted November 1, 2012 Report Share Posted November 1, 2012 What do you think of the smaller barrel ID being an issue? You think it's enough to worry about taking a little off the inside of the choke? 1 Quote Link to post Share on other sites
plattner01 3 Posted November 1, 2012 Author Report Share Posted November 1, 2012 i dont believe there is going to be an issue. the barrels seem to have the same id, now that i have said that i also havent seen any specs on paper of each barrel id either.but if you have the info post up please. 1 Quote Link to post Share on other sites
chevyman097 2,579 Posted November 1, 2012 Report Share Posted November 1, 2012 Some people on other forums have also reported using the S12 poly chokes. I dont see it being an issue unless you put hardened slugs down the barrel. But I cant even speak for that. Just a guess. I got a poly choke for mine. I will post if I have an issue, but I dont see that being the case. Quote Link to post Share on other sites
hdskumm 39 Posted November 1, 2012 Report Share Posted November 1, 2012 Yes, Vepr-12 ID = 18.5 mm, Saiga-12-030 ID = 18.3 mm, but Vepr-12 OD = Saiga-12-030 OD, so railed Saiga-12-030 FSB fits Vepr-12 and vice versa (confirmed by Chef Constructor of Molot). The differences in ID of Vepr/Saiga is not good, IMHO, when you use Saiga-12 muzzle attachments on Vepr-12, inside of the end of the barrel there is a small barrier 0.1 mm radius. This is what I saw about it, but since you guys didn't see any issues I'm ordering one. Quote Link to post Share on other sites
plattner01 3 Posted November 1, 2012 Author Report Share Posted November 1, 2012 (edited) now that i have seen the specs on paper i dont think that .2mm is going to make that much of a difference, i cant even tell looking at both barrels they just seem the same and the thread pitch is the same the poly choke just screwed right on with no issues. was going to the range today to test but other things came up so i have to wait for another day.

brickfield mfg 86 Posted November 3, 2012 Report Share Posted November 3, 2012 (edited) I pulled the PolyChoke II (slotted "flash hider" model) off my S12, put it on my Vepr 12, and it holds tighter groups on the Vepr when shooting slugs than it did on the S12!

plattner01 3 Posted November 3, 2012 Author Report Share Posted November 3, 2012 ah so you can use the choke with slugs ok , always have been afraid of trying it. Quote Link to post Share on other sites
brickfield mfg 86 Posted November 3, 2012 Report Share Posted November 3, 2012 (edited) ah so you can use the choke with slugs ok , always have been afraid of trying it. I would not go tighter than Improved Cylinder, and I was getting great groups last weekend with it wide open - according to the settings, that was supposed to be "Reverse #2". I have a Remington 20 ga. with a smooth slug barrel that shoots well, and it is choked Improved Cylinder. Edited November 3, 2012 by 7.62m43 Quote Link to post Share on other sites

You will get best results if you leave the choke wide open. But it is common for people to use up to imp cyl and imp mod. I choose not to because it can cause some deforming in the slug.

cgp 12 Posted July 24, 2013 Report Share Posted July 24, 2013 Sorry to revive this old thread. Took my VEPR 12 this weekend and used my PolyChoke II Flash. Groups are indeed tighter. Shooting slugs at 50 yards produced a nice 3 inch pattern (open xtra full). However, I noticed my POI shifted dramatically about a good 3-4 inches left from it's original POI with the CSS GK-01 clone. I'm not sure what's causing it. Quote Link to post Share on other sites

I just mention that the barrel damage or injury/death during firing using improper muzzle attacment is not a warranty issue, firing slugs or mugnum/semi-magnum bugshot with S12 on V12 is like playing Russian Roulet - Good Luck.

techvt 0 Posted August 31, 2013 Report Share Posted August 31, 2013 I just put a Polychoke II on my saiga 12 and Im getting POI shift of about 4" right with slugs but in a tight group. Any ideas? Quote Link to post Share on other sites

Any ideas? Adjust your sight to shoot 4" to the right, and go with it! Quote Link to post Share on other sites
techvt 0 Posted September 20, 2013 Report Share Posted September 20, 2013 I ended up switching to a SGM modified choke and a red dot...works perfect now. http://forum.saiga-12.com/index.php?/topic/69203-hk-vs-red-dot-sight-on-saiga-12/&do=findComment&comment=930307 Quote Link to post Share on other sites
