S&W 300 Blackout Upper

Written on Feb 28, 2016

Initially bought this upper to swap out with the 5.56 on my S&W MP15. I wanted the gun to match regardless if using 300 or 5.56. I probably could have done it cheaper with pieces and parts but I like the look of my 5.56 S&W so I went for this 300 Blk out S&W upper. Identical to the 5.56 except of course the barrel, great S&W quality and I can share magazines if I want. It also came with its own BCG. In the end I decided not to share the lower and bought a dedicated S&W MP lower for the 300 Blk out, changed the furniture on it to FDE and got FDE mags so I don't mix up ammo. Once I get an optic I am set to go to the range and then hog hunting. Hope the wife doesn't notice the "whole" new gone when I'm done!
