Which B&T 5.56 Suppressor Fits Your Build?

The Reduced Backpressure System (RBS) from B&T is one of the most comfort-focused designs available on modern suppressors—reducing backblast, cutting down on fouling, and eliminating the need to fine-tune gas systems. For shooters looking for a lighter alternative to the super-heat-resistant B&T SRBS 556, the PRINT-XH series is the go-to choice, with its hybrid titanium/Inconel construction to cut back on weight and length.

Once you’ve decided that the Print series is right for you, the question is which version you will select: the B&T PRINT-XH 556 RBS or the B&T PRINT-XH 556 RBS SC. When optimizing your rifle build, length and weight are critical concerns, and the two inches trimmed between the PRINT-XH 556 RBS vs RBS SC can make a significant difference in both noise reduction and handling. You must carefully consider the trade-offs between the two, comparing their performance specs and the desired role of your platform.

Follow our guide to make the final call on which variant will enhance your setup the most.

Build & Materials

The B&T PRINT-XH 556 RBS and PRINT-XH RBS-SC both rely on a hybrid material construction: an ultralight titanium body and a heat-resistant 718 Inconel blast baffle. The strong titanium housing provides structural integrity at a remarkably low weight while the Inconel baffles excel at absorbing heat from high-volumes of fire.

Both suppressors are 3D-printed and monolithic (single piece, eliminating potential failure points in traditional welded designs). The result is a seamless body capable of withstanding extreme heat cycling and stress while minimizing weight.


Size, Weight, and Handling

Standard PRINT-XH 556 RBS

At just over 7 inches, the standard model sits at the lower end of the “full-size” category for 5.56 silencers. The added internal volume makes it an excellent choice for both standard 16 in carbines or short barrelled rifles. The 13 oz weight (even with the included HUB mount) makes it lighter than many of its contemporaries while preserving the high-heat advantage of Inconel.

Subcompact PRINT-XH 556 RBS SC

The SC (subcompact) version is made for shooters who need to minimize length as much as possible, cutting roughly two inches in length and more than two ounces in weight compared to the PRINT-XH 556 RBS. At about 5 inches long and under 11 ounces when mounted, the SC is ideal for 10.3–12.5 in SBRs and sub-10 in pistol builds.

Gas, Back-Pressure, and Shooter Comfort

Both suppressors use B&T’s proprietary RBS to direct gases forward instead of back into the shooter’s face, greatly increasing shooter comfort and ease of use. Both models list a 2 percent bolt-speed increase, meaning the shooter feels less gas blowback under the charging handle, enjoys cleaner optics/reduced fouling, and can expect their rifle to cycle closer to its unsuppressed baseline. This reduces the need for heavy tuning with buffers or gas blocks (shooters can optimize with fine adjustments).


Mounting & Ecosystem Fit

Both models use the HUB 1.375×24 interface, giving shooters flexibility with mounts from different manufacturers. That means shooters can operate with the suppressor day one with the direct-thread mount or with B&T Rotex and SureFire devices such as the SOCOM Flash Hider and SOCOM Muzzle Brake. For buyers who move a suppressor across multiple rifles, investing in a QD adapter will pay dividends in convenience.


Barrel Restrictions and Firing Schedules

B&T lists no minimum barrel length restrictions on either the PRINT-XH 556 RBS or the SC. Both are also rated for full-auto use, making them ideal for heavy-duty usage even on shorter barrels.

That said, heat management still applies in practice. Hybrid titanium suppressors are strong but can degrade under sustained “mag-dump” firing schedules. Use reasonable firing strings, allow cooling cycles, and treat your suppressor with respect when running full-auto or high-volume training.


What’s in the Box and Warranty

Both models ship with:

  • The suppressor
  • A Rotex-SF HUB adapter
  • The Manual

Both models carry B&T’s lifetime warranty coverage, giving buyers peace of mind on investment in a premium suppressor.


Which B&T PRINT-XH Suppressor Should You Buy?

Choose PRINT-XH 556 RBS if:

  • You want extra gas volume for longer firing strings on 14.5 to 16-inch carbines.
  • You prefer the balance of a 7-inch suppressor with added noise reduction and flash performance.
  • You value hybrid durability but still want a relatively lightweight system.

Choose PRINT-XH 556 RBS SC if:

  • You prioritize the shortest overall length and fastest handling for SBRs and pistol-length rifles.
  • You spend time shooting while inside vehicles or confined spaces where every inch matters.
  • You want the lightest possible system while keeping RBS benefits and HUB flexibility.

Either way you get:

  • A weldless, 3D-printed hybrid build.
  • B&T’s RBS gas control system.
  • HUB 1.375×24 compatibility for mounting flexibility.
  • Silencer Shop eForms support for streamlined checkout.
