I need some AR15 help

[rb765]

I just noticed a few spent shells from my AR15 have small dents where it looks like they slammed against the ejection port. My question, since I am using factory loaded rounds, so lighter loads are out, would a heavy buffer fix this? If not, what can I try to remedy this. It's not a huge issue, but I plan on reloading these cases at some point, so I would rather do without the dents.

I highly doubt that the velocity and direction can be effected to any degree and be able to function reliably.
The AR series rifle was designed as a military weapon and being so the condition of the brass was not a concern tithe designers.

That said i reload and these small dents have never presented a problem for me. Most will actually be rolled out when run through a sizing die. Bigger dents obviously would not.
I guess I've never been overly concerned with the condition of my brass when used in a NATO chamber

On my precision gun, I just put a piece of the soft side of velcro on the case deflector so that they don't get banged up as they eject, I also use a shell catcher so I don't have to go walking around like a chicken pecking for bugs on the brass I am reloading.

If the case is being dented by the ejection port itself, it may be because your bolt is recoiling just a little too far. You can check that by pulling your charging handle all the way back, if the bolt face is going past the back of the ejection port, you can try dropping a couple washers the diameter of your buffer tube in the back behind the spring so that the assembly cant go quite as far back and that may solve your problem.

Bolt/carrier speed is faster than it needs to be. May be over gassed. (16"). H buffer may help. Maybe. Check case deflector for brass marks. Should be consistent marks. Base of fired cases scratched up? Tried different ammo? If your rifle is tuned right it will dump empties in a nice little pile at about 3-4 o'clock without any damage to cases.
