“8.6 Blackout” was developed by Q as the “Big Brother” to the 300 Blackout. Q teamed up with Faxon Firearms to make the barrels which are sparsely available today for AR-10 and the Remington 700 platforms.
8.6 BLK – what is it?
The 8.6 Blackout is widely spoken of as the “big brother” of 300 Blackout. The new caliber, developed by Q, completely re-imagines energy on target by using a faster twist rate – 1:3, compared to the popular twist rates of 1:7 and 1:8 for calibers like 5.56 NATO and 300 BLK.
What about the round itself?
It’s a low-pressure cartridge utilizing a shortened 6.5 Creedmoor case, for use of subsonic and high BC 338 projectiles. And no, you won’t need any special mags for this ammo – it will fit in a standard 308 mag. Ammo will be avaialble in 230-350 grain subsonicand 160-230 supersonic loadings.
Why do I want an 8.6 BLK gun?
When paired with a suppressor, these 300 grain bullets are as quiet as a .22. Plus, with the 1:3 twist, the bullet goes further and impacts harder than your traditional 1:7 twist bullet. The extra rotation is giving the bullet more spin, allowing it to travel further with more punch and expand at a lower velocity.
you need to oil the heck out of them and break them in with 250 rounds of hot, 1350FPS or faster shells. These shotgun like to be run wet so a clear, thin viscocity gun oil like RemOil is the ticket. In the warmer weather I like Mobil 1 5W30 too.
Ladies and Gents, A3G Munitions is a dealer for Venom Defense and Design. We stock the ANTI-VENOM AR9 9mm Compensator and the VIPER .223/5.56mm Compensator. We have tested many compensators in house and feel that these offer the best performance.
If muzzle weight is a concern we really like their Titanium versions as well.
Our complete line of .223/5.56mm ammo works very well with this comp and we are about to announce our 9mm PCC loads that maximize the effectiveness of any AR9 Compensator.
Take a closer look at these on our web site or find me at a 3gun match and demo any of my rifles that are sporting one of these.
