Regular readers no doubt know that our man Leghorn is deeply enamored with 300 AAC Blackout (a.k.a. 300BLK). Back before the round was making the rounds, Nick was singing its praises and predicting a glorious future. The future is now; plenty ‘o gunmakers are making rifles and barrel conversion kits to accommodate the cartridge. CMMG offers five rifles chambered in 300 AAC Blackout (the four above and one more besides) and three barrel options for DIY gunsmiths. In case you’re still not convinced (general ammo availability issues aside), here’s CMMG’s pitch for 300 AAC Blackout . . .
The 300 AAC BLACKOUT (7.62X35mm), or 300BLK, offers increased energy delivery and knock-down power in the same package as a 5.56mm AR-15 rifle. By utilizing a 30 caliber projectile, a wide range of loads are available in the 300BLK caliber for shoooters to tailor the round to their specific needs.
Whether you’re seeking a high-powered sub-sonic solution for suppressed fire [ED: now that’s what I call poetry], or an impressive brush gun, the 300 AAC BLACKOUT should be your caliber of choice! The 300BLK round only requires a different barrel as the rifle uses the entire 5.56 AR-15 platform to function.
