I have a 7.62x39 PWS MK1 SBR I want to run with a suppressor my friend/gunsmith/c3 dealer warned me it likely wont be reliable.
I have many suppressors in 7.62 but this one I was planning on using my YHM ti Phantom if that makes any difference.
He said they have all had problems. I bought it before I knew him he is also a C3 dealer.
I know I need to take it out and run it but is this common with this gun in 7.62x39?
If yes what are the solutions?
I love the idea of this set up since it fits under my desk at work but if I cant count on it thats no help.
Thanks PG

That looks like a Mod 1 or early model. No adjustable gas block? If it's a fixed gas block those long stroke uppers tend to be over gassed for reliability. The suppressor will enhance this so I don't think you'll have failure to fire or feed but you may beat up the gun. You can swap out buffer, different weights, if it becomes an issue.

I have had it for 5-6 years but not really shot it yet... Thank you PG

Sorry I have a lot of toys but lost my places to use them when I got kicked out of the house... Half would be a bargain.

mm should have bought one of these its way more reliable and needs nothing to run a can and its accurate too.
mine is very accurate out to 200 yards with a red dot. big plus is it only looses 150-200 fps with a 10.25" barrel which is chrome plated.
love mine, the factory trigger is really good right out of the box.
