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.
Selling a 9.5" Ballistic Advantage barrel chambered in 300 blackout. It's been on my pistol for about 200 rounds but I'm going in a different direction. It is in excellent shape, and is drilled for a pin on gas block, of which the low profile one pictured is included. It's a BA gas block as...

I recently bought a 300 blackout AR. The 300 ammo is very expensive. I’ve googled on how to make my 300 able to shoot 223 and or 556. All I can find is how to make 223/556 into 300 and most people say all you need is the barrel. Is this true for 300 to 223/556? If not then what else would I need?
For those of you who invested in a 300 Blackout AR, do you actually shot it often or do you find that the cost of ammo makes it so that you don't shoot it frequently (especially suppressed)?
I have 9mm and 45ACP cans in Form 4 processing, and am debating whether to get another 45ACP host or a...
CMMG Mk4T Upper, 300 BLK, 16" barrel, asking $400.
If you want the flip up sights included, then total: $600. TROY Industries, front and rear have tritium inserts. Front is HK style.
Shot about 120 rounds through it. Selling it because I rarely shoot 300 BLK.
Have cash ready for either a stripped upper or complete 300 blackout pistol upper. Mainly looking for a bootleg, pws, or rebel arms upper.
Also looking for either a jp or armaspec silent capture spring.
