Reviews & Ratings for Sons of Liberty Gun Works 300 BLK DRP Profile Threaded Barrel — 1 review — Page 1

I already had a 9" 300 BLK barrel, that is fantastic. But I was looking for another 300 BLK setup that could maximize the performance of supers, and still maintain subsonic performance. The 13.9 is a great option for this. Can pin/weld to 16" with several different muzzle devices, gives supers more velocity, and can still keep subsonic ammo below 1100 fps. Consider running a bootleg adjustable carrier to be able to tweak the gun to run sub's and super's without an adjustable gas block. That has worked really well for me with most 300 blk setups.
