1st range session with my new Sport, also brought along its little brother the awesome 15-22. Fired 150 rds of Federal 55gr 223. What an awesome rifle! Very accurate with iron sights. Standing with brace against a pole I was dead on against milk jugs at 100 yds. Standing with no brace 50 yds and in, very accurate with rapid fire. I really love this gun so far.Probably put a small red dot on it ( Bushnell TRS25 ) Need to get a !@#$load of bulk before next session. Really fun to shoot! As usual my 15-22 performed flawlessly with Federal bulk 36gr. Really easy to transition from one rifle to the other! I'll post again when I put more and different ammo-both 223 and 5.56 thru the sport. Next time I'll post some groupings as well, they were pretty tight as it was just fooling around this time, I'll get more serious next time. It's hard to get serious when you're having so much fun!
