Got the CNC warrior brace/stock adapter installed on my M92 PAP pistol. You have to drill the back of the receiver but then you don't have a big stupid hunk of metal sandwiched under the pistol grip. I also got a detent for the front but I don't have a flash hider yet. Also got an Ultimak rail, Primary Arms red dot, AKT trigger, Magpul PG, AKOU enhanced safety, and a US Machine Gun brace kit
