300 aac blackout

The .300 AAC Blackout (designated as the 300 BLK by the SAAMI and 300 AAC Blackout by the C.I.P.), also known as 7.62×35mm is an intermediate cartridge developed in the United States by Advanced Armament Corporation (AAC) for use in the M4 carbine. Its purpose is to achieve ballistics similar to the 7.62×39mm cartridge, or even more similarly, the 7.92×33mm Kurz cartridge in an M4 while using standard M4 magazines at their normal capacities. 300 BLK ammunition cannot be used in a rifle chambered for 7.62×40mm Wilson Tactical. It is mainly derived from the .300 Whisper concept, but differs in having been submitted to the SAAMI.

    This has been a good rifle, but I'm looking for something I can take on a hiking trip. This is a reliable rifle, and it should goto someone who will put it to use. The barrel can easily be switched out to fire 5.56. Rifle comes with .300 AAC rounds.
