This is my first ar15 build. it consists of a C3 defense lower with an A2 stock and a Rock River Arms Upper assembly. i haven't had the chance to get it to the range yet, but as soon as I do I will post pics. Since this rifle has an 8 twist barrel, 77 grain nosler custom competition bullets should prove quite effective a reducing a coyote's blood pressure to zero out at extended ranges.
