I just built a beauty of an AR, so count me in the EBR fan club. I started with a California off-list CMMG stripped lower, a Bushmaster lower parts kit and A2 stock and a modified grip to make it California legal.
I topped it off with a JP Enterprises JP-15 18” upper, Leupold 1 - 4 x 20mm scope and a JPoint red dot mounted at a 45° on the handguard.
It is a tack driver...and as evil looking as you could want. So thanks Zumbo.
I love the AR-15, but a Kalifornia legal one would be like having sex wearing a space suit.
