Wilson Combat Match Grade 6mm ARC 18" Fluted Stainless Steel Barrel - 1:7.5

The Wilson Combat Match Grade barrel is a precision 6mm ARC drop-in barrel built around the Tactical Hunter profile for AR-platform rifles. Cut from 416R rifle-rated stainless steel with a glass bead finish, this 18" barrel is fluted to shed weight and improve cooling during extended strings of fire.

Engineered to match-grade tolerances, the bore features a 1:7.5 twist rate chosen to stabilize the bullet weights the 6mm ARC cartridge was developed around. The intermediate gas system length pairs the barrel to the pressures and dwell the round was designed for, while the threaded muzzle accepts your choice of muzzle device. The stainless construction resists corrosion and holds the tight dimensional consistency required for repeatable accuracy shot after shot.

Weighing approximately 28.9 oz, this barrel balances heat management with manageable front-end weight on a precision hunting build or carbine project. Manufactured in the USA by Wilson Combat, the Match Grade barrel brings the same standard of construction found on the company's complete Tactical Hunter rifles to a drop-in upgrade for any AR-15-pattern rifle chambered in 6mm ARC.
