Older build I'm moving on from. between 6,000 and 6,500 rounds through it. Runs with no issues, just clearing out stuff to make space and funds for other projects.

-Ballistic Advantage 16" nitride FSP mid-length gas, 1:7 twist

-BCM handgaurd and vert grip

-Geissele LPK w/ mil-spec trigger

-Chrome-lined carrier

-Vortex Red Dot (don't remember which one, it works fine, nice and bright)

-Thril Stock and Pistol Grip

Everything brass case has run without any problems, it doesn't like steel case, but go figure.
