Just got my first 450 Bushmaster upper assembled
This one is subsonic only, pistol length gas system, 9.5" barrel, Aero Precision upper & scope mount 2-7 x 33 CDS Leupold, 7 shot mag.
AP front tube, the adjustable gas block is tuneable through the slots & the tube comes off with three cap screws which is handy,
Looking forward to seeing how it goes up the range tonight.
Weighs 3.34 kgs, 7.4lbs
