matt508 1 Posted February 7, 2012 Report Share Posted February 7, 2012 Hey Guys, Is it normal for the pistion to sightly loosen up? Out of the box mine was wiggling a little. I tried tightening it but it loosened again after 100 rounds or so. I just don't want the bolt carrier to crack in the future. Thanks! Quote Link to post Share on other sites

FunkedOut 91 Posted February 7, 2012 Report Share Posted February 7, 2012 you tightened it? i figured the op rods were pinned like the piston is on an AKM carrier. i'll have to look at mine when i get home... Quote Link to post Share on other sites

matt508 1 Posted February 7, 2012 Author Report Share Posted February 7, 2012 Thanks for the fast reply. Should I unscrew it and put thread locker on it. Or just leave it? Quote Link to post Share on other sites
matt508 1 Posted February 7, 2012 Author Report Share Posted February 7, 2012 Thanks Russian Hammer, I'll just leave it alone. Quote Link to post Share on other sites
RRice 34 Posted February 7, 2012 Report Share Posted February 7, 2012 Guys correct me if I am wrong but you shouldn't be able to loosen or tighten it,correct? That dimple in the threads is where it is pinned 2 Quote Link to post Share on other sites

Razorback 72 Posted February 7, 2012 Report Share Posted February 7, 2012 The dimple on mine is just there to lock the threads into the carrier. It unscrews, no pin. I changed mine ou t(installed a tapco shotgun piston when they were still counting the carrier extension as a 922R part, then changed it back to factory after tapco recalled them) and used red thread locktite on it. Still tight after around 1000 rounds. Quote Link to post Share on other sites
The_Caged_Bird 474 Posted February 8, 2012 Report Share Posted February 8, 2012 They still count the operating rod for 922r... Quote Link to post Share on other sites
Bcrider 68 Posted February 8, 2012 Report Share Posted February 8, 2012 Caged is correct. Op rod counts. If you can spare the change to have someone put the Tom Cole op rod on, it's well worth it. I had Shannon (Cobra) install mine. It is rock solid and I love it. Quote Link to post Share on other sites
G O B 3,516 Posted February 8, 2012 Report Share Posted February 8, 2012 If it bothers you, put green locktite on it - no dissasembly needed. Quote Link to post Share on other sites
Razorback 72 Posted February 9, 2012 Report Share Posted February 9, 2012 (edited) Here is an older link to when everyone was debating on the puck or the bolt carrier extension was the 922R part being counted by the ATF. The explanation of this on this older threadcan be found here.http://forum.saiga-1...iston-for-922r/ Here is a quote from that thread by USMC_LB Back in the day, everyone was looking to find as many 922r compliant parts as they could to replace foreign parts with. The "puck" WAS NOT common knowledge back then. Everyone assumed the gas system for the S12 shotgun was the same as every other AK rifle... The idea was to do what we've been doing on AK rifle conversions and change out the "gas piston". The S12 shotgun bolt carrier "looked" like the AK bolt carrier/gas piston setup. Several companies cranked out some S12 gas pistons and many people here swapped them out. BUT, after closer inspection, someone realized that the design of the gas systems between the AK rifles and the S12 shotguns were actually different from one another. What LOOKED like a gas piston in the S12 shotgun was actually not capable of performing the action that a gas piston has to do (there are no grooves). What looks like a AK gas piston is nothing more than an extension of the boltcarrier. The "puck" in the S12 DOES have grooves in it and performs the duties like that of a standard AK gas piston (that IS pinned to the bolt carrier). The difference being the "puck" in the S12 is not pinned the the bolt carrier. I know this doesnt help you, but it does give you some history to WHY somebody might have a "gas piston" available and not calling it a "puck". LB This part has changed in being counted back and forth several times in the past few years. I don't recall anyone having a letter from the ATF specifically stating that the bolt carrier extension is now to be counted as the gas piston towards 922R, I believe it's still the puck.

G O B 3,516 Posted February 9, 2012 Report Share Posted February 9, 2012 Keep up the good work guys, send uncle BATFuck more letters.The original parts count for the shotguns was 11. Now we are at 15. Anyone care to try for 19? 2 Quote Link to post Share on other sites
The_Caged_Bird 474 Posted February 9, 2012 Report Share Posted February 9, 2012 I agree, its just good to keep abreast of the new regulations... Quote Link to post Share on other sites
kodaline 178 Posted February 9, 2012 Report Share Posted February 9, 2012 What about that legislation that says 922r no longer applies to shotguns that came out last year? Quote Link to post Share on other sites

Razorback 72 Posted February 10, 2012 Report Share Posted February 10, 2012 Thanks for the link and the up-date. Guess I'll go ahead and change the operating rod back out. Quote Link to post Share on other sites

I've never heard of that. It was on the ILE NRA site. Gone now I suppose. I'm sure you can find it if you look. Quote Link to post Share on other sites
