Wilson Combat TR300RCPG16RT7 16" Match Grade 300 Blackout Barrel, 416R Stainless Steel, Bead Blasted, 1:7 Twist, Threaded for AR-15

The Wilson Combat TR300RCPG16RT7 is a 16-inch match-grade 300 Blackout barrel built for AR-15 platforms that demand precision and reliability. Machined from American-made 416R stainless steel and finished with a bead-blasted surface, this barrel represents the kind of uncompromising craftsmanship Wilson Combat has refined over nearly two decades of custom tactical rifle building. Whether you're assembling a subsonic hunting rig, a short-range precision build, or a suppressor-ready 300 BLK upper, this barrel delivers the accuracy and durability serious shooters expect.

The barrel features a 1:7 right-hand twist with six-groove precision button rifling optimized for the 300 Blackout cartridge. A hand-polished bore and feedramps come standard, combined with a crisp precision muzzle crown and optimized gas port geometry tuned for reliable cycling. The Recon Tactical profile keeps weight minimal while maintaining rigidity, and the barrel is threaded 5/8x24 for suppressors or muzzle devices. The .750-inch diameter gas block journal is dimpled for set screw indexing—a detail that prevents unwanted rotation under the abuse of tactical use or high-volume shooting.

Every Wilson Combat barrel goes through a rigorous final inspection and is stamped with precise CNC markings. The 416R stainless steel resists corrosion better than chrome-moly alternatives, making this barrel a solid long-term investment for hunters and shooters who don't want to compromise on bore life or accuracy. Pair it with your preferred upper receiver components and a quality bolt carrier group to build a reliable, accurate 300 Blackout that'll run suppressed or unsuppressed.
