Built for Hard Use
The Mitchell Defense 8.6 Blackout 16" Rifle is engineered to deliver reliable performance with increased versatility across different configurations.
1:3 Twist Barrel for Heavy Projectiles
The fast 1:3 twist rate stabilizes heavy projectiles and enhances rotational energy, improving performance with both subsonic and supersonic ammunition.
Increased Barrel Length Performance
The 16" configuration provides increased velocity and improved ballistic efficiency compared to shorter platforms, making it more versatile across a wider range of applications.
Precision Ground MD10 Bolt Carrier Group
The MD10 BCG is machined and precision ground to achieve a near frictionless surface. Treated with Blacknitride+™, it delivers durability, corrosion resistance, and smooth operation.
A5 Buffer System with Flatwire Spring
The A5 length buffer system combined with a proprietary flatwire AR10 spring and heavy buffer helps reduce recoil impulse and maintain reliable cycling.
Adjustable Gas System
The adjustable gas system allows the rifle to be tuned for suppressed or unsuppressed use, improving reliability and reducing excess gas.
Billet Receiver Set
Machined from 7075-T6 aluminum, the billet upper and lower receivers provide strength, durability, and a precise fit.
Why Choose a 16" 8.6 Blackout Barrel?
The 16" barrel length provides increased velocity and improved overall performance compared to shorter configurations.
Compared to a 12.5" platform, the 16" configuration offers improved ballistic efficiency and greater flexibility when using supersonic ammunition.
While still capable in suppressed setups, the 16" platform provides a broader range of performance across different applications.
For shooters looking for a versatile 8.6 Blackout rifle, the 16" configuration offers a strong balance between performance and flexibility.
8.6 Blackout Velocity and Performance
The 8.6 Blackout cartridge maintains efficient performance across different barrel lengths, with velocity increasing as barrel length increases.
