I've been looking at the ejection port in the receiver. It seems very tight and not much bigger at all than the cartridge. Has anyone opened it up slightly and do you guys who know what you're doing recommend it? I was thinking of just filing it a very little bit top and bottom.

Why can't they work from the factory? Is this too much to ask? It works perfectly with the .223 upper, why not with the 450? OK, rant over

I have a one inch group at 50 yards and a 2.5 inch group at 100, all with Hornady factory ammo- couldn't be happier . Wish I knew what the problem was- Bushmaster didn't say.
Thanks for all your help guys. Takin it out opening day- Saturday, hopefully will have pics and stories to tell.
