Battle Arms Tanker 300P 7.5" 300 Blackout AR Pistol with Brace

The Battle Arms Tanker 300P delivers compact firepower in a stabilized AR pistol platform optimized for 300 Blackout performance. This 7.5-inch barrel configuration maximizes the cartridge's subsonic capabilities while maintaining reliable cycling with both supersonic and subsonic ammunition.

What Makes This Different

The Tanker 300P features a purpose-built short barrel optimized for 300 Blackout's pressure curve, delivering consistent velocities that standard 5.56 barrels cannot match with this cartridge. The included stabilizing brace provides shoulder contact for improved accuracy while maintaining pistol classification. Battle Arms' proprietary gas system ensures reliable extraction across the full range of 300 Blackout loadings, from 125-grain supersonic to 220-grain subsonic rounds.

Key Features

• 7.5-inch barrel with 1:7 twist rate optimized for heavy subsonic bullets
• Mil-spec upper and lower receivers with Type III hard coat anodizing
• Adjustable gas block for tuning with suppressed and unsuppressed fire
• M-LOK compatible handguard with full-length Picatinny top rail

The 300 Blackout cartridge reaches optimal performance from short barrels, making this 7.5-inch configuration ideal for close-quarters applications and suppressed use. The platform maintains effectiveness out to 200 yards with supersonic loads while offering near-silent operation with subsonic ammunition and appropriate suppression. Weather-resistant finishes and proven direct impingement operation ensure function in adverse conditions.
