Sorry if this has been covered in another thread. I tried to search and didn't find any info.
I just took my 9mm AR to the range for the first time today. I was using Blazer brass ammo 115 grain FMJ. I used this in my CZ and Glock's with no issue and it seamed to run clean.
The cases coming out of my AR were all coming out about between 1 and 2 o'clock (I am a lefty) and all were extremely dirty. All primers looked fine with no signs of over pressure. None of the cases were deformed.
Is this normal? Do I need to use a heavier buffer or change my buffer spring?
10.5 inch CMMG barrel with A2 flash hider for now.
Using a New Frontier Armory BCG
Dedicated New Frontier Armory Glock Lower
At this time it is in a pistol configuration (90 days on Form 1 and counting)
The buffer tube is a sig buffer tube (taken off of another pistol that uses standard M4 springs and buffer)
Buffer is the New Frontier Armory supplied 9 mm buffer/spring and has an insert supplier by NFA instead of quarters.
Thanks
