(5 out of 5) Affordable AR15 rifle, American parts and craftsmanship
by Edward from Erlanger, KY on April 21, 2026

A dependable rifle, affordable and all American-made, and uses .223/5.56 NATO. It is a nice-looking, dependable rifle that is new to the market but is growing with the .300 Blackout. I love mine. Upper and lower receiver aluminum and Picatinny rail, green and red dot sight. 30 round magazine. A real American gun for Americans.
