Delivering a heavy-hitting .30 caliber round on target, .300 BLK was originally designed around being a subsonic round for use in shorter barrel, suppressed rifles. Additionally, .300 BLK set out to utilize as many M4/AR15 parts and ammo components as possible. Great for home defense and suppressed use in subsonic loadings. Built on the Mk4 AR15 platform. Features EML handguard, full length M-LOK slots on both sides and the bottom of the handguard as well as M-LOK between the top picatinny rail sections; ZEROED parts including: pistol grip, drop-in trigger, 60/90 degree ambi safety, ambi mag catch, extended mag release button, muzzle brake AR15- bolt catch, polymer dust cover and ambi charging handle. Includes Magpul 30rd PMAG.

Caliber Dictionary
The Below Information Has Been Provided From Our Gun Caliber Dictionary And Is Meant For Informational Purposes Only. It Is Not Intended to Describe The Unique Specifications For This Ammunition.
The 300 AAC Blackout (300 BLK) was developed in 2009/2010 by Advanced Armament Corporation and approved by Sporting Arms and Ammunition Institute (SAAMI) in 2011. Based on the 223 Remington case necked up to 30-caliber, it was intended for the M4 Carbine and designed to function in standard AR15/M16 magazines. Thus converting an AR to 300 AAC Blackout requires nothing more than an upper receiver group. Dimensionally it is identical to the 300 Whisper, but the 300 Blackout is fully standardized. Supersonic and subsonic ammunition is manufactured, with a 125-grain bullet producing 2215 feet per second, while the subsonic load uses a heavier bullet at much lower velocity: 220-grain bullet at 1080 fps. Military applications are obvious; as a sporting cartridge performance is similar to the 7.62x39. — Craig Boddington
