The Faxon Ascent AR-15 Rifle (Faxon part no. FX5116) is built entirely around Faxon’s own AR-15 action and bolt carrier group, chambered in 5.56 NATO and also safe for .223 Remington. A 16-inch Faxon barrel with an A2 flash hider and a 1:8 twist rate handles a wide range of bullet weights, while the M4 precision adjustable stock and a 13-inch M-LOK aluminum handguard round out a rifle built for reliable, everyday use. It ships without fixed sights, leaving the top rail open for the optic of your choice, and holds a 30-round magazine. At roughly 36 inches overall and about 6.12 pounds, it’s a manageable, well-balanced AR-15 for the range or home defense.
