The wife and I just got back from shooting 200 rds. through my S&W AR15. I bought it in Feb. and with today's outing it has 1200 rds. through it with ZERO problems. I would recommend this rifle to anyone looking for a quality AR. I second the red dot/eotech for a sight. I will be ordering a Vortex red dot shortly. After shooting my friends rifle with an Aimpoint I was sold on the idea. Plenty accurate for coyotes to 300 yds. and quick enough for home defense.If you stick with the popular makers, S&W, Bushmaster, Colt, Stag, etc. you should be just fine.
