  • 8.6mm x 43 Blackout

    The NEW 8.6 BLK From Faxon Firearms and Q. The 8.6 BLK has an OMG 1:3 twist.

    Faxon Firearms has always been at the forefront of barrel development in the industry, so it's no surprise that they are developing the barrels for the new 8.6 Blackout ammunition.

    I didn't know who Q is:

    Makers of the Honey Badger, The FIX, and other UNPOSSIBLY badass stuff. If you want cookie cutter, you've come to the wrong place.

    The Geronimo tee shirt is a must have for serious social encounters. (ROFL)

    Utilizes a shortened 6.5 Creedmoor case for use of subsonic and high BC projectiles
    Current Ammo Companies in Development: Gorilla, Hornady, Black Hills, and Discreet Ballistics
    Just what we need is 4 ammo companies ignoring older calibers to provide ammo for a new one!

    For WROL, don't plan on foraging ammo for it or anything else. IMO, anyone preparing for a survival world best have very common calibers.

    Every time a new caliber comes out, I wonder will it last for the long run.

        Good thing I have new fangled and old fashioned calibers. Remember smokeless powder is just a passing fad!

          Your "new fangled and old fashioned calibers" said it well.

          Here, about as new as it gets is a 6.8 SPC. Its weakness, it is not a forage to find caliber. ROFL.

          I wouldn't mind building a .221 FB rifle. That caliber has always interested me. Based on what my TC .221 FB can do has me interested in a rifle.

          It's Memorial Day here in the US.

            You can see how little the light bullet is seated, Id like to know that. they talk 300 grain for subsonic, no mention of weights for supersonic. M

              When, I was a teenager hunting, I saw what I thought was a nice sized buck in the brush. When it stepped where I could see its head, it didn't have horns. It was one of the biggest whitetail does I've ever seen.
              After that, I bought a Weaver K-series and had the 35 Rem Marlin 336C drilled and tapped to mount it.

              Even when my eyes were 20-10, I used a scope. After cataract surgery, my eyes are 20-15. In case, the way eyes are measured is different in Canada; 20-15 means what I see at 20', normal vision (20-20) sees at 15'

              As an example, even when my vision was 20-10, I could break clay birds at 200 meters; however, I could not break the pieces with a scope I could.

              8.6 blackout super sonic load weights are 285-350 grain subsonic and 160-225 supersonic. IMO, a lot of shooters want subsonic and a silencer.
              Whether you were at SHOT Show 2022 or not, you probably heard a little something about this new “8.6 Blackout” round that Q developed and how Faxon Firearms is helping change the game and bring 8.6 BLK to life. We’ve been working with Q on 8.6 BLK barrels for awhile now and finally got to share the news that yes, we are going to be releasing six 8.6 BLK barrels this year! Read on to learn a little more about this awesome new round and the barrels we’re making to support it.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.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. 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. Currently, Gorilla, Hornady, Black Hills, and Discreet Ballistics are in the process of developing ammunition in this caliber. And no, you won’t need any special mags for this ammo – it will fit in a standard 308 mag. 285-350 grain subsonic. 160-225 supersonic. For some more info on testing and manufacturing the 8.6 ammunition, check out the Discreet Ballistics page. What kind of barrels is Faxon making, then? We’ll have our own 8.6 BLK barrels for both AR-10 and Remington 700 platforms. The full offering (for now) will be: Remington 700 Platform:8″ Light Palma, Remage style with 1:3 twist12″ Light Palma, Remage style with 1:3 twist16″ Light Palma, Remage style with 1:3 twistAR-10 Platform:8″ Big Gunner with 1:3 twist12″ Big Gunner with 1:3 twist16″ Big Gunner with 1:3 twistSo… is Faxon making 8.6 BLK guns? As of right now, no we are not. We’re just making the barrels. However, you’ll be able to build yourself an awesome 8.6 gun with some incredible parts from all kinds of companies. For example, one of the builds we brought to SHOT Show was a KRG Chassis, Falkor Defense action, Thunder Beast suppressor, and one of our barrels (check it out below). What are you thinking for MSRP?Still figuring out what our final MSRP will be, but our rough ball park for these barrels will be $225-350 price range, depending on length.Ok, we have to ask… what about the barrel life? We can’t confirm just yet the barrel life on these, as they’re still really new. We’re currently mid-testing one and have gotten up to 1000 rounds through it. What barrel contours will be available? AR10 barrels will be a modified big gunner profile. Remington 700 barrels will be a modified light palma profile. What will gas length be on the AR10 barrels?8 and 10 pistol length, 16 carbine length. Expected release date? First half of this year – estimating late March/Early april. Sign up to find out! Still have questions? Can’t wait to get your hands on one? Head to our 8.6 BLK page to learn more (we’ll update it regularly) and make sure you’re signed up to receive all 8.6 news updates – including an in-stock notification when we finally have them available for purchase.

              As Faxon mentioned the "AR-10." Although it is an excellent choice, it lacks the standardization of the AR-15. According to what I've read, each AR-10 manufacturer's components may or may not fit another manufacturer's AR-10.

              My pet peeve with the AR family is they don't use standard nomenclature. Although, there are exceptions with rifles, they are either long action or short action.
