The Armalite M-15 Competition AR-15 rifle in .223 Wylde/5.56 NATO is built for shooters who demand precision and speed on the range. This 18-inch competition carbine combines a lightweight platform with match-grade components designed to deliver tight groups and reliable performance in timed and tactical disciplines. At 7.8 lbs, it's nimble enough to handle rapid target transitions without sacrificing the inherent stability you need when accuracy counts.
The heart of this rifle is a free-floating stainless steel barrel paired with an Armalite tunable muzzle brake—gear that lets you dial in performance to match your ammunition and shooting style. The adjustable gas block takes personalization further, letting you tune the rifle's cycling to run smoothly with the loads you're running. A low-profile handguard keeps the setup sleek and manageable, while the Timney single-stage trigger breaks at a crisp 3 pounds, giving you the predictability competitive shooters depend on.
The receiver is machined aluminum with a hard-coat black finish, paired with an MBA-1 adjustable stock that lets you dial in length of pull and comb height for your natural shooting position. This level of fit matters when you're stacking shots—the more the rifle fits your body, the faster you return to target. The rifle ships with one 30-round Magpul PMAG, ready to load and run. Whether you're new to competition or sharpening your skills at a local 3-gun match or precision rifle event, the M153GN18 gives you a platform built to win.
