I really enjoy my PAP m92. Traded for it about 2 years ago. It came with the SB47 brace on it, but I went ahead and SBR'd it. Put a USMAchineGun.com lite stock on it and it has been a very reliable fun .30 cal SBR to have.
That looks AWESOME. Any wiggle with the stock? Any complaints at all? I'm looking at doing the exact same SBR with a M92.
I like the SBR ideas! I wonder what the implications are if I had to hand this down to one of my kids. I also like the arm brace idea.
