18 Inch 6MM ARC Barrel with Rifle Gas System

The 18 inch barrel is manufactured from 41V50 Chrome Moly Vanadium steel with nitride finish for corrosion resistance and surface hardness. The 1:7.5 twist rate stabilizes 6MM ARC projectiles across the common weight range, supporting accuracy with match grade ammunition. Government profile balances weight distribution and barrel stiffness for precision shooting applications. 5R rifling reduces bullet deformation and fouling compared to traditional rifling, potentially improving accuracy and extending cleaning intervals. Rifle length gas system provides smooth cycling characteristics with reduced felt recoil, making this configuration well suited for precision shooting and long range applications. The .750 gas block journal accepts standard low profile gas blocks. 5/8x24 thread pitch accommodates common muzzle devices for 6MM ARC including suppressors, brakes, and compensators.

Freefloat Keymod Handguard and Upper Assembly

The 15 inch super ultra slim freefloat Keymod handguard provides a lightweight platform that eliminates contact with the barrel, supporting accuracy potential by preventing handguard pressure from affecting barrel harmonics. Anti rotation tabs lock the handguard to the barrel nut, preventing movement during use. Keymod attachment points allow mounting of accessories including lights, grips, and bipods without additional rail sections. The 7075 T6 aluminum upper receiver features M4 feed ramps for reliable feeding and anodized finish for corrosion protection. The micro low profile gas block sits beneath the handguard for a clean appearance and reduced snag points.

6.5 Grendel II Bolt Carrier Group and Components

The QPQ nitride 6.5 Grendel II complete bolt carrier group is manufactured from 9310 alloy steel with nitride finish for enhanced lubricity and corrosion resistance. The 6.5 Grendel II bolt face dimensions are compatible with 6MM ARC cartridges, providing proper case support and extraction. QPQ nitride treatment creates a hard surface that resists wear during extended firing schedules. The AR-15 M4 Mil-Spec charging handle provides reliable manipulation for charging and clearing operations. The complete bolt carrier group includes bolt, carrier, gas key, cam pin, and firing pin.

Special Operations Stock and Buffer System

The Special Operations stock is constructed from glass filled polymer for strength and reduced weight in black finish. The stock provides adjustable length of pull to accommodate different shooters and shooting positions. Complete Mil-Spec buffer system is included with buffer tube, buffer, recoil spring, castle nut, and receiver end plate. The 5/8x24 GI birdcage flash hider reduces muzzle flash signature and protects the muzzle threads when suppressors or other devices are not installed.

Lower receiver not included. Follow safe handling and manufacturer instructions. Ensure compatibility with your specific AR-15 lower receiver before installation. Verify headspace and function after installation. Ensure compliance with all applicable laws.
