The rifles were fired on two separate range trips, but on both days we experienced the typical Western Oregon cold, rainy winter weather that we’re well known for. It didn’t keep us from ringing out these two new AR-15 builds, although it may have affected the outcome! Regardless, both rifles shot very well. Per my usual routine, I fired 5-shot groups at 100 yards from a solid bench and counted the best 75% of the groups fired. The 16-inch rifle was tested using a Vortex Strike Eagle 1-8x24 scope set at 8x, and the best six of eight groups fired, using only the Black Hills’ remanufactured 60-grain V-Max factory load, averaged 1.14”. The best group was 1.123” and the worst was 1.330”. This is a light and fast-handling “CQB” type rig that will probably wear a Trijicon MRO red dot optic for the rest of its life, and still—with an 8x scope and (albeit excellent) remanufactured ammunition—it performed admirably, averaging 5-shot groups of just over one MOA. I built the 20” heavy barreled rifle with Eastern Oregon “sage rats” in mind. These miniature prairie dogs provide a challenge and a hell of a lot of fun, and they require serious accuracy at long range. On this one, I mounted a Vortex Viper PST Gen II 5-25x50 scope. This is an excellent piece of glass at a price point that will not break the bank, and it helped us shoot some really nice groups! We fired a total of 16 5-shot groups using the Black Hills 60-grain V-Max load mentioned 35 JAY DOBYNS
