Built for Suppressed Performance

The Mitchell Defense 7.5" .300 Blackout Pistol is engineered specifically for shooters running suppressed configurations. Each component is selected to support reliable operation with subsonic ammunition.

1:5 Twist Barrel for Heavy Projectiles

The fast 1:5 twist rate is designed to stabilize heavier .300 Blackout projectiles commonly used in subsonic ammunition, ensuring consistent performance.

Adjustable Gas System

The adjustable gas system allows the user to tune the platform for suppressed use. This helps reduce excess gas while maintaining reliable cycling.

Armorlube-Coated MD Carbon Cutter Bolt Carrier Group

The MD Carbon Cutter bolt carrier group features an Armorlube coating that enhances lubricity, reduces friction, and improves corrosion resistance. This promotes smooth operation in suppressed environments.

Lightweight Recoil System

The lightweight buffer and spring are designed to function with lower-pressure subsonic ammunition, helping maintain reliable cycling and smooth operation.

Compact Platform Design

At 5.5 pounds, the 7.5" configuration provides an extremely compact platform that takes full advantage of the .300 Blackout cartridge’s performance in short barrels.

Why Choose a 7.5" .300 Blackout Pistol?

The .300 Blackout cartridge was specifically designed to perform efficiently in short barrels, making the 7.5" configuration one of the most effective compact options available.

Compared to longer configurations such as 10.3" .300 Blackout, the 7.5" platform offers a smaller overall footprint while maintaining strong performance with subsonic ammunition.

Short barrel configurations pair well with suppressors when using subsonic loads, making this setup a strong option for compact suppressed platforms.

For shooters prioritizing compact size and suppressed performance, the 7.5" configuration is one of the most efficient options available.

Product Description

The Mitchell Defense 7.5" .300 Blackout Pistol is designed for shooters who want a compact platform optimized for suppressed use.

The 7.5-inch CrMoV barrel features a fast 1:5 twist rate designed to stabilize heavy subsonic projectiles. This allows for consistent performance when using ammunition commonly paired with suppressors.

The system operates on a direct impingement system with a pistol-length adjustable gas system, allowing the user to fine-tune the platform depending on ammunition type and configuration.

Combined with the Armorlube-coated MD Carbon Cutter bolt carrier group and lightweight recoil system, the platform delivers smooth and reliable operation.

Finished with B5 Systems furniture and a QD sling mount end plate, the Mitchell Defense 7.5" .300 Blackout Pistol provides a compact and efficient platform.

Why Choose .300 Blackout?

The .300 Blackout cartridge is designed to perform efficiently in short barrels while maintaining compatibility with the AR platform. It is well suited for use with subsonic ammunition and suppressors, making it a popular choice for compact platforms.

.300 Blackout vs 5.56 for Short Barrel Platforms

If your priority is a compact suppressed platform, .300 Blackout offers significant advantages in short barrel configurations.

Subsonic vs Supersonic .300 Blackout

The .300 Blackout cartridge can be used with both subsonic and supersonic ammunition depending on the intended application.

Subsonic .300 Blackout

Subsonic ammunition uses heavier projectiles and travels below the speed of sound. When paired with a suppressor, this combination produces reduced sound compared to traditional rifle cartridges.

Supersonic .300 Blackout

Supersonic ammunition uses lighter projectiles and higher velocities, offering improved ballistic performance and extended range.

This flexibility allows the platform to be adapted to different applications.
