Compact 338 ARC Upper Assembly

The 10.5 inch HBAR profile barrel is chambered in 338 ARC with a 1 in 8 twist rate for projectile stabilization. The phosphate finish offers corrosion resistance and surface hardness. The pistol gas system is matched to the barrel length for reliable cycling. The barrel features 5/8x24 threads for muzzle device compatibility.

M-Lok Freefloat Handguard

The 10 inch handguard features M-Lok attachment slots for modular accessory placement. The freefloat design isolates the barrel from handguard contact. The 6061-T6 aluminum construction maintains a lightweight profile while providing structural integrity.
