Why Choose the RESOLUTE MK4 in .300 BLK?
Supers and Subs, One Platform
From flat-shooting supersonics for hunting/defense to quiet, low-blast subsonics (with a properly configured muzzle device or suppressor where legal), .300 BLK shines as a multi-role cartridge.
16.1" Barrel = Practical Precision
The 16.1" length offers a balanced blend of velocity, compact handling, and legal simplicity—great for training, field carry, and home/property defense setups.
Free-Float Modern Handguard*
A free-float M-LOK® forend preserves point of impact under sling/barricade pressure and gives you the real estate to mount a weapon light, hand stop, QD cups, and cable management.
Optics-Ready Upper
The Picatinny rail makes mounting a red dot, prism, or LPVO straightforward, so you can tailor the rifle to your mission.
Tungsten Cerakote® Durability
The low-glare Tungsten finish is tough, corrosion-resistant, and easy to maintain—built to look good after long days on the range and in the field.
*Handguard length/profile and small parts may vary by production run—see your product label for exact configuration.

Frequently Asked Questions
Q: Will it run both subsonic and supersonic .300 BLK?
