S&T Mosin-Nagant Unfixable Issue???

[tommygunner9]

So, when you cock back the bolt and let it go, the bolt just shoots forward like a slingshot. It turns out the piston lock loop is bent too far forward (because it's made out of crappy pot metal) and is not locking the piston. Hence, the trigger can't be pulled.



The one on the the right is the stock, bent piston lock loop.

I saw that evike.com has a King Arms piston lock for the Mosin-Nagant that's made out of steel and meant to replace the crappy stock one. I immediately ordered it and was hopeful.

Here is the link: www.evike.com/products/54569/

Upon installation, it turns out that it isn't compatible with the S&T, although the description on evike.com clearly boasts, "Compatibility: King Arms Mosin Nagant rifles and other compatible Nagant Airsoft rifles." Hmmmm, besides Zeta-Lab, Accuracy Fire and S&T, the only other Mosin-Nagant available is the Redfire PPS one, which now they decided to throw King Arms into the mix, calling it "King Arms Redfire Nagant." You can just disregard Zeta-Lab and Accuracy Fire, because they have been gone so long. This part was obviously not manufactured for those brands. It HAS to have been manufactured for the Redfire and S&T (as I have assumed).. But apparently not.

Anyways, the reason why it's not compatible is because the hole in the middle of the perpendicular loop is way too big. The bolt does lock back, but now the trigger is stuck! The piston cannot clear the hole! Upon comparison to the stock part, the hole in the stock part is WAY smaller.



So, I come here with the question.. Is there anything I can do? Or is my Nagant doomed to be a wall hanger? Please let me know. Thanks!

I'm no expert on gun maintenance, but having dealt with a near failure of a conversion, I might know something or two about improvisation. You might be able to get a small cylindrical piece of steel that fits inside that hole from a local shop or a scrap heap at your local high school and drill out a smaller hole inside that. That would have to be the size of your stock hole. Then JB weld it into place and that might help. Just my two cents. Hope you can find a way to get it working

Yeah, I thought about some kind of steel sleeve or some filler to make the hole smaller. Looks like I'm going to have to get creative!

First off, I don't know why there are two threads of this. One would be suitable.

Second. King Arms owns Redfire, they are the same company. So, the part King Arms make is for the Redfire one. On the Redfire Mosin, you are supposed to remove an inner tube from that "I" hole on the piston lock and place it into the I hole of the replacement piston lock. The inner tube will make the hole smaller for it properly function.

Evike is also known to have a horrible webmaster, its one of the few problems with Evike. I didn't even know that S&T made a Mosin, but they usually do their own weird things (especially with clones), and its not Redfire/King Arms.

My suggestion is to do a springer conversion on it, or commission one to do so. I'm doing the same (looking for someone to take the job), and I'm doing it because, even when its working like it should out of the box, the gas loading and BB loading systems make it damn near unskirmishable. You gotta carry a gas can with you, which requires precision and gas runs out after every ten shots, and its work to load BB's. In a game, you will constantly do both, while under fire.

I worked on one, and got it running and all that, and I was really excitied for it, but just constantly reloading gas and BB's when even testing it out and chrono-ing and getting familiar with shoot it reallllyyyy drove me away from it.
