The AR-50A1 National Match is similar to our standard AR-50A1 with some VERY important differences. The AR-50A1 NM is produced from selected components: The National Matchâ€™s 33 inch barrel is three inches longer than the standard AR-50A1â€™s barrel. The barrel has eight flutes. The flutes help with cooling and reduce unnecessary weight while maintaining accuracy-enhancing stiffness. The barrel has a 50 BMG Match chamber instead of a standard military chamber.
The result: sub MOA accuracy. We werenâ€™t kidding when we told you weâ€™ve made the best even better.
ArmaLite has also developed a â€śSkid Systemâ€ť for the AR-50A1 National Match. Itâ€™s meant for serious match use and comes standard, NOT as an expensive add-on. The ArmaLite Skid System provides parallel rests on the rifle that are parallel with the bore of the rifle so when it recoils it will recoil straight back. This has been requested by match shooters, some of whom have made their own. The front skid attaches to the slot in the forestock similar to the way bipod rails are attached. The rear skid attaches to the buttstock. Armalite developed the Skid System without modification to the AR-50A1â€™s original parts so the system can be used by shooters who already own an AR-50A1 and want to use their original stock with NO MODIFICATIONS.
The AR-50A1B rifle is the newest incarnation of the wildly popular AR-50 chambered for the powerful 50 BMG cartridge. A single shot bolt action rifle featuring a unique octagonal receiver bedded down into a V-shaped stock. Designed to be an economical answer for the challenges of long range shooting, the AR-50A1 is amazingly accurate and with its massive fluted muzzle brake, it has a very gentle recoil. The AR-50A1 is a highly refined rifle which is a stark and refreshing difference that maintains its superiority over its competition.
ArmaLite's great .50 has been refined, with smoother action, attractive new bolt stop, and even greater strength than the original AR-50. The same great accuracy, but now even more Beautiful.
AR-501B .416 Barret
The AR-501B .416 Barret rifle is just like the AR-50A1, but chambered and re-barreled to accept the .416 Barrett cartridge. Because of that, the AR-50A1-.416 Barrett boasts the same ArmaLite patented V-Blockâ„˘ Bedding Wedge and V-Block Stock that assure absolute strength and repeatability for superb accuracy. The aluminum stock reinforces the receiver like a bench-rest sleeve.
Added to all of that is the famous .416 Barrett cartridge, which contains a .416 caliber projectile capable of sustaining supersonic speeds out to the 2,500 yards, which is the key to achieving long range accuracy. The .416 Barrett cartridge uses a lighter, narrower bullet that was designed using low supersonic drag equations and results in a significantly high muzzle velocity and exceptional ballistic performance.
