I am getting ready to purchase an AR style rifle for 3 Gun and was wondering if anyone is familiar with Lewis Machine and Tool, and if so specifically the 5.56 Defender Model 16. The price at my local shop is at $1200 with flip up sites 2 mags sling.Seems to have a great feel to it, really like the sop mod stock and the way it feels. I am just curious about reliability and preformance.
