Posted a while back about PDW 300 or CZ Scorpion. Decided to go with my 300BLK SBR.
Changed to the LWRC Ultra Compact stock kit which is 2" shorter than normal buffer tube. Changed out the 12" rail that went over the suppressor to a 7" rail so can shoot it in suppressed and makes it more maneuverable if I want to throw it in a bag or something. Changed the NV scope to a Aimpoint PRO. Thing is tiny!!! If my suppressor mount wasn't so long that would save another 2 inches lol.
This is compared to a 16" carbine.
