Anderson Manufacturing's M4 Carbine (AM15-M416LE) improves on a familiar and reliable mil-spec rifle. It is chambered in .223/5.56mm and has a 16-inch M4 heavy barrel with an Anderson Phantom 5.56mm flash hider. It has a front-mounted, low profile gas block with a Picatinny rail and a 7075-T6 aluminum receiver. The M4 Carbine has a hard-anodized finish and is also treated with RF-85 for faster and more reliable cycling without traditional wet lubricant, virtually eliminating failures due to excess dirt and carbon fouling in the action, and operation at cooler temperatures. This LE model has a Magpul MOE 6-position stock, Hogue beavertail pistol grip, 6-inch free-floating modular forearm with a rail, and is completed with an A2 front sight post and includes one 30-round Magpul magazine.
