ArmaLite M15 5.56x45mm NATO Semi-Auto 30+1 RD M153GN13

This rifle includes the ArmaLite M15 semi-auto rifle in 5.56x45mm NATO caliber, one 30-round magazine, a permanently attached tunable muzzle brake, Timney single-stage competition trigger, MBA-1 lightweight precision stock, adjustable gas block, low-profile 12-inch free-floating competition handguard, and a Raptor ambidextrous charging handle.

The permanently attached, tunable muzzle brake reduces recoil and muzzle rise, helping maintain accuracy and allowing quicker follow-up shots during competitions. Because you can fine-tune it, shooters can adapt the rifle's control to their specific preferences and shooting style.

The adjustable gas block allows you to change the gas flow to match your ammunition, reduce recoil, and optimize rifle cycling. Follow the instruction manual to make incremental adjustments, typically small changes at a time while testing performance. Adjustments are recommended whenever you switch ammunition types, add or remove accessories, or encounter cycling issues.

This rifle is specifically engineered for competitive shooters, such as those involved in 3-gun competitions, target shooting, or marksmanship events. Its compact, lightweight build and premium competition components allow for rapid maneuverability, accurate shooting, and fast target transitions.

The barrel itself is 13.5 inches long. However, with the permanently attached (pinned and welded) tunable muzzle brake, the overall barrel length reaches the legal 16 inches.

Use high-quality 5.56x45mm NATO ammunition. While it can also fire .223 Remington rounds safely, the rifle is explicitly chambered for and performs best with 5.56 NATO ammunition.

Regular cleaning after each shooting session keeps your rifle functioning properly. Disassemble as outlined by the manufacturer’s instructions. Clean your barrel, muzzle brake, and chamber thoroughly with appropriate firearm cleaning solvents and lubricants. After cleaning, apply lubrication in areas recommended by ArmaLite. Always ensure proper reassembly before operation.

Yes, the MBA-1 precision stock included with this rifle is adjustable for length-of-pull (LOP) and comb height. Adjust it accordingly for improved comfort, accuracy, and overall performance.

This rifle features an installed Timney single-stage competition trigger, offering a clean, crisp trigger pull. While the trigger itself is factory-set for performance, it can typically be replaced or serviced by a certified gunsmith if desired.

Yes, this rifle is equipped with a Raptor ambidextrous charging handle, making it convenient and comfortable for both right-handed and left-handed shooters.

Yes, the free-floating competition handguard has sections to mount optics, sights, lights, or other tactical and competition accessories easily. Installing optics or iron sights is recommended based on your shooting discipline for maximum accuracy and performance.

While primarily designed for competitive shooting, the ArmaLite M15 rifle can be used for small-game hunting and, if desired, practical home-defense scenarios. However, keep in mind its primary purpose involves optimized competition features such as precision triggers and adjustable gas systems, which may differ from dedicated defensive or hunting rifles.

Yes, this rifle accepts standard AR-style magazines. It ships with one 30-round magazine but can use aftermarket magazines compatible with AR-pattern rifles.

This rifle is designed to be compact and lightweight for quick and agile maneuverability. Exact weights vary slightly due to accessories, but generally, competition-focused builds like this are lighter than standard AR-pattern rifles.

ArmaLite recommends following basic barrel break-in procedures for precision firearms. Typically, this involves firing rounds individually or in small groups, cleaning frequently during initial use to maximize barrel life and performance.
