8.6 Blackout AR10/AR308 Barrel Premium Stainless

MÔS-Tek’s version of the 8.6 Blackout Custom Premium Barrel Stainless

Match Grade
416R Stainless
5 R Rifling
1:3 Twist Rate

8.6 Blackout (8.6 BLK) is a centerfire rifle cartridge that uses a shortened casing from the 6.5 Creedmoor.  It is designed to be used in Bolt Action rifles or as an AR10 or AR308 rifle.  It uses the 1:3 Twist Rate and can be utilized as a supersonic or subsonic cartridge.

What’s the big deal with the 1:3 twist rate? This monumental 1:3 twist greatly enhances the energy of the large 8.6 blackout round.    

If you like .308 then what the 8.6 will give you is more energy.  It’s specifically designed for short barrels.  With an expanding 350 grain bullet, accurate to 300 yards, it hits hard.  If you want a lightweight gun that can be extremely quiet, shoot from long distance and bring down big (we’re talking BIG) animals then the 8.6 Blackout is most likely for you.

Like the 300 Blackout the 8.6 Blackout 1:3 Twist is designed primarily for suppressed shooting.  For the super-sonic shooter however there are loads being developed.

Having been dubbed as the 300 Blackouts “Bigger Brother” primarily due to the 300 Blackout catering to the AR15 market.  The 8.6 Blackout will be available in the AR10/.308 as well as a bolt gun platform.  Larger = Better right?

The skeptics that thought the 8.6 Blackout 1:3 Twist was never going to come to practical fruition are taking a seat and taking notes as it finds it’s place among the up and coming hunting cartridges.   The 8.6 Blackout 1:3 Twist has made it’s presence known and will be around now for the duration!

Welcome to the family 8.6 Blackout 1:3 Twist, pull up a chair!
