My 450 Bushmaster build is complete! I took it to the range yesterday after work and it shoots amazing! 50 yards I had 4 rounds on top of each other. Shot one round at 100 yards to verify 100 yard zero and it was right in the 1" center bullseye. Now, the only question I have is the empty brass weren't flying that far when ejected. I shot a total of 17 rounds of Hornady factory ammo and there was no issue other than what I consider weak ejection. I was using the two new Bartz 5 round hunting mags I purchased. Very nice! I'm not too concerned given how the rifle performed but just wondered if I should keep an eye on the "weak" ejection?
Love this gun!!!
