Product Description

Update, October 9, 2026: ATF no longer requires a Form 4, tax stamp, fingerprints or registration for suppressors, short-barreled rifles, short-barreled shotguns or AOWs. They now transfer on a standard Form 4473 with a background check. Anything below that mentions a Form 4, a wait or a tax stamp was written before this change. What changed

B&T XH556 RBS Titanium 3D Printed Suppressor — Subcompact Gray

The B&T XH556 RBS Ti PRINT Subcompact is the compact K configuration of B&T’s 5.56 RBS titanium suppressor — shorter and lighter than the full-size XH556 for rifles where minimum system length is critical. Same RBS Rotary Baffle Stack geometry and additive-manufactured baffle cores as the full-size, compressed into a subcompact form factor. Gray titanium finish. Ideal for shorter AR-15 builds, SBRs, and pistol-length hosts.

B&T USA: Swiss Suppressor Engineering

B&T (Brügger & Thomet) is a Swiss defense company with decades of experience manufacturing military and law enforcement equipment. B&T USA brings that precision Swiss engineering to the American NFA suppressor market — featuring titanium and Inconel alloy construction, proprietary RBS (Rotary Baffle Stack) geometry, and advanced additive-manufactured baffle cores for maximum suppression in lightweight, durable packages.

RBS: Rotary Baffle Stack Technology

B&T’s RBS (Rotary Baffle Stack) design arranges baffles in a rotational pattern that maximizes gas expansion volume and turbulence — producing more suppression per inch of suppressor length than conventional straight-stack designs. Combined with titanium and additive-manufactured structures, RBS enables B&T to achieve exceptional weight-to-suppression ratios in their XH and X series rifle suppressors.

Additive Manufacturing: 3D-Printed Baffle Cores

B&T’s PRINT suppressors use metal additive manufacturing (3D printing) to create internal baffle geometries that are impossible to machine conventionally. This allows complex gas-path shapes that maximize suppression efficiency while maintaining structural integrity at high cyclic rates — all in titanium for minimal weight impact.

Buying a suppressor now: a Form 4473 and a background check. No Form 4.

Since October 9, 2026, ATF no longer requires a Form 4, tax stamp, fingerprints, photos or registration to buy a suppressor. It transfers like any other firearm: you fill out a Form 4473, pass a NICS background check, and it is yours. No months-long wait.

  • Texas buyers: suppressors are legal under Texas law. Western Sport has been an SOT / Class III dealer since 2007.
  • Outside Texas: we ship to an SOT dealer in your state, who completes the 4473 with you. Your state’s law still decides — some states ban suppressors, and some only allow ones registered with ATF.
  • Want it registered anyway? ATF still accepts a voluntary Form 4. Ask us.
