MMYoung57 0 Posted January 2, 2013 Report Share Posted January 2, 2013 Recently purchased a forearm/stock kit (SKU: DE_KIT_02) from Saiga-12. After mounting the new forearm and stock I'm having trouble cycling rounds. Before the install my Saiga-12 would cycle low brass Winchester shells as fast as I could pull the trigger. Now it won't cycle them at all and even have had a couple stovepipes with some Remington Express 2 3/4" 00 Buck. I have a TAC-47 Autoplug and didn't do anything to it when I put the forearm on. Has anyone else experienced this? If so any suggestions? If you need any other info to help with me out just ask and I'll provide it as best I can.

rnemhrd 165 Posted January 2, 2013 Report Share Posted January 2, 2013 Have you tried back tracking to see if the gun will cycle then? It would'nt take long at the range to switch the stock and handguard out to see where the issue is. Was it working with the Auto Plug before you changed the furniture out?

misterT 174 Posted January 2, 2013 Report Share Posted January 2, 2013 I have read on here before that some quad rails can cause this because they pinch the gas tube causing the piston to freese up. I am not sure if that is your problem but you might remove the gas valve and see if the piston moves freely. The other thing is have you cleaned your gun recently, if not it may just be a coincidence that it started malfunctioning after changing the furniture. Quote Link to post Share on other sites
MMYoung57 0 Posted January 2, 2013 Author Report Share Posted January 2, 2013 @ rnemhrd - no I haven't "back tracked" was hoping I wouldn't have to. Yes it was working flawlessly with the TAC-47 before I put the new furniture on it. @ misterT - I cleaned it after first shooting it with the new furniture, thinking that might be the problem. Shot it after the cleaning and actually had one of the 00 Buck stovepipe on me. I will check out the gas piston tonight. On another note, when I cleaned it before this last shoot, I noticed on the left side on the upper front part of the forearm there was some carbon on the inside part of the forearm. There is a hole in the gas tube there, is that normal? BTW, I bought this gun at an estate sale so am not the original owner so I'm not sure if there was any "modification" done prior to my purchase.

zenman223 460 Posted January 2, 2013 Report Share Posted January 2, 2013 Yes that hole is normal and some hand guards have been known to cause issues b/c they cover that hole and dont allow the gasblock to function correctly. This is most likely the problem. Some members have remedied this problem by drilling a hole through the handguard to line up with the hole in the gasblock(this should be last option) You may need to re adjust the autoplug. Try tuning the autoplug, if that dont work remove the handguard, if it cycles without that handguard you know what the problem is. Quote Link to post Share on other sites
ChileRelleno 7,071 Posted January 2, 2013 Report Share Posted January 2, 2013 MMYoung57, Welcome to S12.com. You've received some good replies for trouble shooting so far, I've nothing to add at this time besides the Welcome. Quote Link to post Share on other sites
Guns4Gods 1 Posted January 3, 2013 Report Share Posted January 3, 2013 Can someone post a pic of this hole lol . I've got a hand guard on the way from saiga12.com and now I'm not sure i want to change it if it will cause reliability issues . Quote Link to post Share on other sites

Mullet Man 2,114 Posted January 3, 2013 Report Share Posted January 3, 2013 (edited) ^^^there ya go. It's on the gas block, middle left side, if you've shot it recently there should be carbon deposit around it. Just look for the hole or have someone put some hair around it. lol Edited January 3, 2013 by Mullet Man Quote Link to post Share on other sites
Guns4Gods 1 Posted January 3, 2013 Report Share Posted January 3, 2013 Thank you ! I'm gonna have to check this out I never noticed it . Thanks again chile Quote Link to post Share on other sites
Guns4Gods 1 Posted January 3, 2013 Report Share Posted January 3, 2013 Funny how something so little can make a difference . Thanks to mullet man also . This place has so much info it can be overwhelming . Quote Link to post Share on other sites
ChileRelleno 7,071 Posted January 3, 2013 Report Share Posted January 3, 2013 (edited) Do not block the vent hole, it will affect cycling. Its purpose is supposedly to vent air pressure from behind the puck allowing to move against the op-rod with the least amount of counter pressure. Some rails block or impede it enough to cause problems, if your rail blocks it, simply drill a hole, fixed. In the past some people with under gassed guns have attempted to fix the problem by blocking this hole, tap-n-screw/weld/etc, its not a fix. It appears Mullet Man needs to put some hair around it, cause him thinking it was middle of left side, he'd be dry humping her thigh.

Guns4Gods 1 Posted January 3, 2013 Report Share Posted January 3, 2013 That's funny . If mine is not blocked should I clean it when I clean the rest of the gun or just leave it alone ? Thank you again Quote Link to post Share on other sites
ChileRelleno 7,071 Posted January 3, 2013 Report Share Posted January 3, 2013 Once in a blue moon I might pick the hole, otherwise its pretty much self cleaning. Quote Link to post Share on other sites

LOL i like it old school. but i meant middle of the gas block, as in between the barrel and gas tube. Quote Link to post Share on other sites
MMYoung57 0 Posted January 3, 2013 Author Report Share Posted January 3, 2013 Thanks for all the info, being new to the Saiga 12 I wanted to make sure I wasn't going to do anything that could "overtake the plumbing". Will get busy with these suggestions this weekend and will let everyone know the results. Mark Young Quote Link to post Share on other sites

TIA, Mark Young The main culprit is going to be the recoil reduction stock, and a close second is that tri rail. Try test firing with each of them off. Quote Link to post Share on other sites

Those pogo stick recoil reducing stocks absorb recoil the gun needs to cycle properly. Why I said to back track parts out at the range. Pedal is right. Quote Link to post Share on other sites
Guns4Gods 1 Posted January 5, 2013 Report Share Posted January 5, 2013 Would the tapco t6 pistol grip kit cause the the same pogo stick affect ? I picked one up till I can do the conversion but once again this has me wondering about reliability issues ? I'm super glad this all was brought up it has helped in a lot of ways Quote Link to post Share on other sites
rnemhrd 165 Posted January 5, 2013 Report Share Posted January 5, 2013 Should'nt. I believe they are solid. You can't compress it when locked can you? Quote Link to post Share on other sites
Guns4Gods 1 Posted January 5, 2013 Report Share Posted January 5, 2013 No it's solid but I've not had a chance to shoot it with the stock on it yet . It's just my 12 has be so reliable that I would hate to do anything that would change that. I just wanted some reassurance from people on the forum with experience thanks for responding .
