S&W FPC Complete Disassembly - Bolt Catch Design Flaw? 

@HiepNguyen-ig4pl 👍hope it helps. Thank you for viewing the video.

So far the bolt catch is the only part that I am having issues with (bent)...great trigger being stock/factory.

👍thank you, glad the video was helpful.

Just so I understand you correctly. First, have you disassemble the mags by taking the baseplate, lock plate, spring and follower out of the mag body? If no obstruction, you should be able to manually push down on the follower when the mag is empty. As for the feed ramp it is held together by spring and pin and should sit flush with bottom half of receiver. Secondly, you mentioned you are not able to charge the rifle with bolt catch holding the bolt open using the CH, is that with or without an empty magazine inserted? If a empty magazine is inserted and the bolt is locked back, you will not be able to use the charging handle since the follower in the mag is pushing up on the bolt latch lever. The only way to have the bolt move forward and close is to push down on the bolt hold latch. It is difficult to do since the nub/protrusion is almost flushed against the receiver.

I found the bolt catch arm inside on left side was bent. Yes definitely S&W should update the latch to extend out further.

It says in the manual it's only meant to be a slide catch and not a slide release.

Thanks, yes that's a 1" riser mount that came with the Riton and fits me perfectly without having to press my cheek firmly to the stock.

Perfect, that's the size I had ordered. Is your muzzle device on with a crush washer? I'm not 100% sure how to clamp the barrel for installation.

@@johnw2604 yes, I installed the comp with a crush washer. There was enough room for me to clamp the barrel forward of the handguard with some soft jaws to install the muzzle device. You can also use a good piece of leather wrap around the barrel in a vice since it didn't take much to turn the comp and get it indexed. or just remove the nuts/bolts on handguard to expose the entire barrel...there were a bunch of them fasteners 😁

Yes I still think it's a good buy. Hopefully either S&W or aftermarket companies will come out with a updated lever. I am all for S&W sending any of their new product to test😉. Thanks.

👍glad you found content helpful. Thanks.

From what I see, they are not the same design. Although the trigger shoe is similar, internally the parts are different. The biggest difference is one is hammer fired and the other is striker fire. So, the standard trigger upgrades (spring kit) will not work. I'll try to do a follow-up video next time I disassemble the FPC for cleaning.

Sorry, no they are different.

I haven't looked, but are you referring to the back of bolt near the firing pin? or bottom of the bolt?

The back of the bolt, around the firing pin. Where the hammer hits.

@mnrodriguez I would expect impact marks, and since the bolt moves back on the hammer on recoil, the marks you see to be normal. I'll keep a lookout and report back if anything changes on mine.

​@@redarmory, thank you!

I hear you, it was a lot of bolts and nuts 😉 but needed to get in there to see what was causing the bolt hold open issue. Probably not going break it down as far as I did next time, just for cleaning.

When you say, won't fold do you mean the latch on the right side by ejection port will not unlatch? First verify chamber is empty, follow field strip procedures and make sure on disassembly to note any damage parts. If you are able to, remove the two pins holding the barrel assembly to the fire control assembly. Hard to figure what could be causing the issues without additional details.

I hope there will be some support for this rifle. I am not aware of any companies that is putting out aftermarket bolt hold, but Taccom have a few upgrades for the FPC. Thank you for contributing to the discussion.

@@redarmory fr I feel like we are all waiting for an upgraded bolt release! When will companies start making parts like for the SUB2K. This is a fantastic gun, it deserves aftermarket support

@@justauser I agree, so much potential just needs a good following and will make it worth it for the aftermarket companies to support it.

@@redarmory I think it's had alot of success and it's one of the most popular, and sold out, in my neck of the woods! Quality piece that folds up nicely. What's not to love

To push down on hammer and let the bolt slide past the hammer.

@@redarmory Thanks

Not sure what you mean, like more close up during disassembly/assembly or just zoom out more?

🤣🤣🤣I think it was Betamax...still learning and sometimes I forget to setup camera to 16:9

"Why" it's a design flaw in my opinion? After 2000rds notice that the bolt would not stay locked back on last round when magazine was removed. With mag in, it would lock back but bolt would fall forward once mag was removed. Disassembled rifle completely and found the bolt catch (U-shape) on one of the leg was bent and was not getting good engagement of the bolt to hold it open. Straighten out the part and now just waiting to see if it happens again. Seems to me the leg is too weak to hold up in the long term.
