Finished up a PDW pistol in 300 BLK using an Aero PEW lower (at wife's request).



Barrel is 6 inches (IIRC) with a Griffin Armament taper mount liner comp / suppressor mount that just barely clears the handguard.





I think I'm going to put an BCM KAG on it so I have a good reference point to keep from getting a hand over the barrel and want to put a caliber marked dust cover on it since it's not 5.56/.223, but I think this is otherwise done.

Doesn't scrunch up as tight as an MP5K, but with the stock out and suppressed it's in the ballpark.
