NRA High Power Service Rifle Class Questions
I'm building my first AR, and it will be primarily used for NRA High Power league matches. I want to stay in the Service Rifle class but need some clarification.
From the searching I've done so far, flat top uppers seem to be more prolific a2 uppers. However, would a flat top with detachable carry handle still be legal? Also, I'm planning on running a 20" H-BAR contour barrel, and I was wondering if it has to be threaded to use an A2 flash hider or can it be plain with no comp / flash hider?
