The 1:7 twist rate is engineered to stabilize a broad spectrum of projectile weights, from lightweight 55-grain bullets for high-velocity applications to heavier 77-grain match projectiles for precision shooting. This versatility makes the upper suitable for training, competition, and recreational shooting across diverse ammunition types.

This dual compatibility provides shooters with maximum flexibility in ammunition selection.

Mid-Length Gas System and Upper Receiver Design

The mid-length gas system is optimized for 16-inch and longer barrels, providing enhanced recoil management and smoother cycling compared to carbine-length systems. This gas system length reduces felt recoil and muzzle rise while supporting more consistent extraction and ejection, contributing to improved shooter comfort and faster follow-up shots during rapid-fire sequences. The micro low-profile gas block provides a streamlined profile that fits cleanly under freefloat handguards while ensuring reliable gas system function. The 7075-T6 aluminum upper receiver offers exceptional strength-to-weight ratio, reducing overall upper weight while maintaining structural integrity for reliable long-term performance across demanding shooting applications.

Bolt Carrier Group and Charging Handle

The included complete bolt carrier group is forged from 8620 alloy steel, a material selected for its strength and durability under the high-pressure cycling demands of the AR-15 platform. This material provides excellent wear resistance and fatigue life, supporting reliable operation across thousands of rounds. Paired with an AR-15 Mil-Spec charging handle, the complete upper ensures smooth, dependable operation and broad compatibility with aftermarket upgrades and accessories. This combination of proven components delivers consistent cycling and extraction performance across varied shooting conditions and ammunition types.

Trinity Force KMX Keymod Freefloat Handguard

The 15-inch Trinity Force KMX Keymod freefloat handguard is crafted from 6061-T6 aluminum with a hard coat anodized finish, providing enhanced durability, corrosion resistance, and a long-lasting surface finish. The freefloat design isolates the barrel from external contact, supporting enhanced accuracy potential by eliminating pressure points that can affect barrel harmonics during firing. The Keymod attachment system offers lightweight mounting points for lights, laser devices, vertical grips, bipods, and other accessories at multiple positions along the rail. The extended 15-inch length provides ample mounting space and covers most of the barrel for a modern, streamlined appearance while supporting versatile accessory configuration.
