No gas and dirt in the receiver makes cleaning and shooting lots of rounds sweet. With that said they are way louder since all the gas comes out the front end.Well maybe one of these days. I don't SBR for the hassle or the suppressor for the $$ but a piston gun is doable.
I have a POF in a 7" barrel it is to bad they do not make any more. Adams makes piston uppers I don't think they make a 6.8.I saw the LWRCI 6.8, anyone else make one?
I've heard that if you ever have to replace the bolt in your piston gun to replace the buffer tub at the same time. But then again I have no,0, nada experience with piston guns.I will say this and lot of people and that includes me think the piston makes the BCG move a little up when it strikes the buffer spring. I have seen a little wear but not big deal so far.
i don't know that for sure as I have never had to,replace. I would think since my POF bolts are chromed and the BCG is Ni coated it would not wear out as fast as buffer springI've heard that if you ever have to replace the bolt in your piston gun to replace the buffer tub at the same time. But then again I have no,0, nada experience with piston guns.
