300blk
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 a rifle 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 Soviet cartridge in an AR-15 while using standard AR-15 magazines at their normal capacity. Care should be taken not to use 300 BLK ammunition in a rifle chambered for .223/5.56 or 7.62×40mm Wilson Tactical.

I have a Sig Bravo4 prism sight. These were made to compete with the Acogs and are no longer made. Pretty hard to get your hands on now and even harder for the 300blk model. It's been on my 300blk build for about 100rnds but I decided I'd rather go with a different style optic.

I make a 3D printed Vacuum Chute to aid in making 300 Blackout brass from 223/5.56 brass. It speeds up your cutting by eliminating the need to stop and leaves very little to clean up afterwords. The 223/5.56 necks and brass shavings will be vacuumed up and the remaining brass to be converted...
