So I've been having some ejection issues with my most recent build. It seems that the spent case is fond of the area directly above the magazine and refuses to leave, like a bad party guest. It exits the chamber just fine, but for some reason the front of the case flips up and wedges in the groove of the charging handle while the back of the case is wedged against the bolt. This jams up the works real good. Now, I have a ton of PMC Bronze .223 and that's pretty much all I've shot through this rifle. And I know it is reported to by pretty weak stuff. I have put a few boxes of Federal/American Eagle through it without a hiccup, but not enough to really be sure it's just an ammo issue. I've also read several times the the 14.5 mid-length setup is not happy working with low power ammo, but I've read just as many reports where guys claim that their rifle eats anything under the sun. So I'm looking for some input from the guys who shoot a lot more than I do. Ammo? Bolt issue?
