Wilson Combat TR556SBRCG11RT7 Match Grade 11.3" 5.56 NATO Barrel, Stainless Bead Blasted, 416R Steel, Carbine Length, SBR Tactical Profile, 1:7 Twist, Threaded for AR-15

The Wilson Combat TR556SBRCG11RT7 Match Grade 11.3" 5.56 NATO Barrel is a short-barreled rifle (SBR) barrel built for shooters who need accuracy and reliability in a compact, maneuverable package. Machined from American-made 416R stainless steel on computer-controlled equipment, this barrel combines the precision of a match-grade build with the practical balance of a carbine-length gas system. At 11.3 inches, it's ideal for close-quarters work, tactical training, and registered SBR builds where portability matters without sacrificing performance.

Wilson Combat's two decades of AR-15 custom builds inform every detail here: the bore and feed ramps are hand-polished, the chamber is optimized for both 5.56 NATO and .223 Remington, and the muzzle is precision-crowned for consistent ignition. The SBR Tactical profile—a medium taper—manages heat well during sustained fire and keeps the front end light for fast target transitions. With a 1:7 right-hand twist and six-groove precision button rifling, this barrel stabilizes 68–80 grain match and hunting bullets reliably. The carbine-length gas system pairs with a .750" diameter, dimpled gas block seat (use a low-profile block for best reliability), and 1/2" x 28 muzzle threads accommodate suppressors, brakes, or flash hiders.

This is a no-compromise barrel for builders who prioritize precision and durability. Every unit passes Wilson Combat's rigorous final inspection—crisp CNC markings, tight tolerances, and a chamber tuned for mil-spec reliability. Whether you're assembling a registered short-barrel rifle for specialized shooting, training, or tactical work, the TR556SBRCG11RT7 delivers the accuracy and longevity you expect from a true match-grade build.
