Hey y'all. Got a chance to fire my new Armalite(upper)/ Eagle Arms(lower) AR this weekend. Here's how it went:
Pulled bolt back to chamber first roud, and let it fly... stopped short as the HP bullet didn't seem to want to ride up the chamber grooves into the pipe. If I pulled back the charging handle again and let it go, it woulld chamber the round, although that is largely because the bullet had been crammed into the casing a little futher. That round would fire just fine, then I'd jam on the next shot, due to the same problem, except the following round would have the bullet slammed well back into the casing, making ot worthless. I got to fire my gun about 10 times before it simply wasn't any fun firing a single shot AR15 with a 30 round capacity, and I suddenly longed for a muzzle loader. (hehehe)
Anyway, I tried 4 different Okay magazines, and had the same issue with all of them. This upper/ lower combination is all brand new, up to this point unfired. The upper and lower were bought separately. The one consistant variable was the ammo... all 62 grain (I think) hollow point rounds. I haven't tried ball rounds yet.
First question: Are HP rounds known for failure to feed issues?
Second, Should I expect my new Armalite upper to be able to feed HP ammo?
Third, If ball ammo seems to feed just fine, is there maybe a break in period before HP rounds will feed reliably? Not that I really need to use them... i am just a bit curious.
Even though I have yet to fire ball rounds through this rifle, I am feeling pretty confident that the HPs are the problem. So, needless to say, no more HPs for me. But, I'd still like to think that my AR will be reliable with most any decent round I want to fire through it... HP, SP, or FMJ ball stuff.
Any notes or advice?
Thanks guys,
Jaffo
