9mm AR aero precision parts

[RussellC]

Assembled many AR15 rifles, first one in 9mm.
Bought Aero Precision upper, lower, bolt, tube spring and buffer, all for their epc parts.

Test functioning it with 9mm snap caps I noticed that unlike manipulating the slide on a semi auto, the shell eject...with the AR they do not fly out like a pistol, they are just kind of rolling out.

Surely this isn't normal function? Brand new areo precision 9mm bolt...thought maybe it needed to be actually fired with live ammo, but my semiauto pistols fling them out.

Thanks in advance,

Should be fine when actually firing live ammo

I wouldn't worry about it. My PSA ejects differently depending on the load. With a light load they barely eject but I am running a 9mm buffer with extra weight.

I was hoping that....to the range!

My buffer is heavier, aero precision for their epc 9 mm. I tried to use all one outfit for the parts.

Single source is a good idea, although recently I tried a Rock River upper on my PSA lower and it ran fine.

Oh I'm sure many mix and match work, this was first 9mm carbine, so I wanted to avoid any distractions and have only one manufacturer to question with any hickups. Plus, I am a big aero fan!
