The AR-47 or the AR-15 chambered in 7.62x39 caliber is one of the most infamous weapons to date when it comes to stopping power in a modular platform that is renowned all around the world. The AR-15 is one of the most customizable and modular platforms in firearms history and technology, and enables multiple calibers to be set up and fired through its platform. The 7.62x39 originating from the legendary AK-47 is a hard-hitting round that delivers a significant amount of kinetic energy upon impact on the target. This Military Spec Rifle blends the AR15's familiar design with the AK-47's powerful and inexpensive 7.62 x 39mm round. The 4150 CMV Chrome Moly M4 Profile Barrel in these rifles is only one example of the high-end components available at an affordable price. Both the top and lower receiver are made from Type III Class II hard-coat anodized, mil-spec forged 7075-T6. M4 feed ramps and a Picatinny rail on the top of the upper receiver are standard features. This model's gas block is railed for a low profile, making it perfect for adding optics or a secondary set of iron sights. Magnetic particle inspection is used to guarantee the flawlessness of the bolt carrier and the gas key.
