PTR 32P PDW 8.5" 7.62x39 Pistol

Just a few photos of my PTR 32P PDW.  It's an HK 91 clone chambered in 7.62x39.  I hoped this was a newer gen 2 with 5/8x24 muzzle threads so I could use a SureFire Socom muzzle brake for my 762-Mini suppressor. But it's the slightly older version with 15x1 threading so my only option was the SureFire Socom flash hider.  I milled a few pockets in the tines to cut down on the "ping" that plagues pronged muzzle devices.  I also found out that the welded-on section of picatinny rail is too high to co-witness my Primary Arms Micro Dot with the iron sights even with the lo-mount.  Now to wait for my tax stamp.

I replaced the 15x1 Surefire Flash Hider with a 15x1 to 5/8x24 thread adapter from Griffin Armament and added Surefire 7.62 Socom Muzzle Brake.  With such a short barrel, I prefer a brake to act as a sacrificial baffle to protect the suppressor.  The thread adapter adds roughly 3/4" to the barrel.  I also replaced the wobbly MP5 handguard with an HK53 length handguard from HKParts.net.  It's long enough to fill in the gap at the barrel trunnion and has much less slop.
