Few materials can handle the heat of high-volume fire better than Inconel. With 5.56 being one of the most popular cartridges for rapid semi-auto and full-auto platforms, the Inconel offerings from B&T are some of your top contenders.
For shooters looking for peak heat-absorption, the B&T SRBS 556 is a rugged, full-size can made entirely from Inconel, engineered for the heaviest firing schedules with B&T’s Reduced Backpressure System (RBS) to keep gas in check. For shooters seeking a more lightweight heat-resistant silencer, the Print XH 556 RBS trims off ounces with its hybrid construction of titanium and Inconel while maintaining the RBS advantage.
Do you need maximum heat resistance in a full-sized package, or merely excellent heat resistance in a lightweight configuration? Read on in our comparison between SRBS vs RBS to learn which option is ideal for you.
The SRBS 556 is a monolithic (single-piece) unit of 718 Inconel, a composite alloy known for its strength at extreme temperatures. The 3D-printed suppressor features no weld-lines, reducing potential failure points. This design allows the suppressor to weather aggressive firing schedules and hotter loads, making it ideal for full-auto usage.
The Print XH takes a hybrid approach to cut down on weight while preserving as much heat-resistance as possible. The titanium body keeps the system light while the Inconel blast baffle absorbs the heat from high-volume firing. The low-flash endcap further reduces visible muzzle signature, providing an advantage in low light conditions.
Mounted on standard carbines, the B&T SRBS 556 adds moderate length at just over 8 in. While its 20 oz weight is a consideration for shooters, the comparatively short length keeps its balance predictable and stable. This can even be a feature for shooters looking to mitigate muzzle climb from sustained full-auto fire.
The B&T Print XH 556 RBS trims a full inch from the SRBS and cuts down on nearly half its weight. The difference is immediately noticeable on short-barreled rifles (SBRs), keeping these shorter platforms high speed and low drag. This is especially important for usage in vehicles or close-quarters battle (CQB) scenarios, reducing fatigue and improving rifle handling during quick transitions.

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. The SRBS is rated at about a 1.9 percent bolt-speed increase, while the Print XH is listed at under 2 percent.
This means the shooter feels less gas blowback under the charging handle, enjoys cleaner optics and 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 (though some shooters may still prefer fine adjustments).
Both suppressors are HUB 1.375×24 compatible, giving buyers flexibility across mounting systems.
The SRBS 556 and Print XH 556 RBS ship with a Rotex-SF HUB adapter, which works with B&T Rotex and SureFire devices such as the SOCOM Flash Hider and SOCOM Muzzle Brake.
Both designs are weldless and backed by B&T’s warranty support. For the latest package details and included accessories, check the product detail pages directly.
