My 450 build
Posted: Sat Dec 24, 2016 2:46 pm
First off want to say hi. I am a new guy here, I have been wanting a big bore AR for some time now. I built a 6.5 Grendel and it has been just great super accurate. My buddy built a 458 Socom and I was going that route but, I like being different lol. So here it is a 16" Brownells 1:20 twist on a PSA upper/lower, hyper fire comp flat trigger. "Not in this picture but in second pic" I opened up the ejection port probably a little bit to much...but, at least it clears the ejected cases.
I was worried about the 450 bushmaster with all the horror stories, I hear about feeding/failure to fire ect. My buddy said your going to regret getting the 450 that is until he saw it in action. I think you guys just say how it sucks because you don't want everyone to know just how awesome this round really is...lol
I had zero failures of any kind. I used some modified Elander 556 mags they hold 8 just fine but I am sure if I clip a few coils off the spring it would hold and feed 9 to 10 rounds just fine. The Elander mags have thick followers so reshaping them with a dremel drum sander didn't skeletonized them. I also modified a 20 round Pmag that holds 7 rounds and feeds awesome too. Plus it is much better from a shooting bench.
