Ok, I got my first 308 AR platform, and went Sunday for a quick test run.
I got it in a trade, it's PSA build Gen 1, with a Anderson 18" bbl, AIM NIB carrier, and some crappy cheap keymod handguard that I'm going to change. I fired 50 rounds out of it just to test her out, and she preformed flawlessly. I was only using g irons, but was nailing clay pigeons at 100 effortlessly. But the ejection is a bit off from what I'm used to. I've only had 546 ARs. It put all of the brass into a nice little pile, but at a 2:00 o'clock position. I'm used to my AR ejecting to a 4 or 5 o'clock. Is the 2 o'clock ejection normal for these? |

Ammo?
And is it slinging it or just throwing it at 2:00? Pattern may change with different ammo. Common complaints for 308s are overgassed requiring different buffers or adjustable blocks or removal of one of the ejector O-rings.... Sounds like yours is functioning normally but stand by for more opinions.. |

My .02 on ejection patterns in either .308/7.62 or 5.56/.223 Ar's is that if it's running flawlessly I don't worry about it.
It's probably a tad over gassed, a lot of .308's (and 5.56/223 rifles for that matter) are, especially from the budget class. You can spend a lot of money chasing perfect ejection pattern that may or may not enhance reliability or durability. If it were mine, I'd leave it alone until or unless a functioning problem pops up. Taming over gassing on a 308 is not a huge undertaking, nor is it as simple as it is with a 5.56 rifle. Yes there are heavier shorter DPMS pattern 308 carbine buffers available, but they are $$$$. You could also get an adjustable gas block, and or pull your receiver extension off (assuming your running an AR15 extension w/ DPMS pattern short 308 CAR buffer) and swap it with a longer extension made for allowing the use of AR15 buffers with 308 carriers, and use cheaper AR15 H, H2, H3, etc...buffers. I think the Vltor A5 extension works for this conversion, but don't hold me to it, as I am content with the AR15 extensions/DPMS short Car 308 buffers I run on mine, and haven't dove to deep into it. |

I don't get why people care where their gun ejects, as long as it is not in my face (lefty) and outside of the gun I'm happy. Thanks for the input guys. |
| If you have a .308 AR that functions flawlessly, leave it the hell alone! Most .308 ar's are problematic. I have owned several, from a variety of manufactures. From bargain basement to high end and they all had to be tinkered with. Both of my current .308's dump the empties around the 2 position. As already stated, that could change with ammo. |
