.450 Bushmaster AR15 with 16" barrel. I have put about 100 rounds through it, and it's a lot of fun. Recoil is stiff but manageable. Likes a lot of oil on the BCG and buffer. It doesn't like flat nose ammo, but pointed rounds cycle just fine. My tightest groups came from Winchester Deer Season XP, 250GR, Extreme Point. I averaged around 1.5" groups. I have no doubt some other shooters could get that tighter. Optic and mount I used have sold separately.

Cerakote done by @LuckySG, who did a fantastic job of matching the sling.
