For operators who need a short, durable suppressor that keeps rifles running cleanly in close-quarters and duty applications, the right canister makes all the difference. Tactical teams and patrol officers require a balance of minimal blowback, compact length, and proven durability to perform under pressure.

Banish Speed K The BANISH Speed K is a compact 5.56 suppressor built to deliver maximum sound reduction in a 4-inch package. Designed with clipped-wall baffles, a finned blast chamber, and controlled flow technology along with a vented 4th baffle, the Speed K minimizes gas blowback while preserving reliable function.

Key features and materials

The Speed K uses 100% Inconel construction to resist erosion and reduce heat retention on sustained strings—critical for duty cycles. Clipped-wall baffles and a finned blast chamber concentrate sound suppression without excessive backpressure. Controlled flow and a vented 4th baffle specifically address the two chief complaints with short cans: gas blowback and increased cyclic behavior. The manufacturer reports only a 5.8% increase in blowback versus unsuppressed shooting, enabling most rifles to function without additional modifications.

Performance and testing

Built in collaboration with Federal Ammunition and law enforcement professionals, the Speed K passed seven rounds of SOCOM testing—an aggressive durability standard where one SOCOM “round” equals 1,440 rounds fired in a short period. Few short suppressors survive a single SOCOM event, and the Speed K surviving seven demonstrates exceptional robustness for tactical use. At 4 inches, it preserves maneuverability for vehicle entries and tight-room movement while providing the benefits of a 5.56 suppressor.

Compatibility and mounting

The BANISH Speed K ships with a direct-thread Industry Standard Hub mount (1.375×24 HUB) so teams can pair it with quick-detach hubs or thread it directly to common 1/2×28 muzzle devices. Muzzle brakes and other devices are offered separately, and buyers should account for the required $200 federal tax stamp. View product details and pricing: View product details and pricing

The Speed K’s 5.56 focus makes it ideal for patrol carbines, SBR builds, and precision duty rifles where controllability, subsonic compatibility, and low recoil matter. At an MSRP around $999, it sits in the premium compact suppressor tier for operators who prioritize performance and durability.

For teams equipping patrol rifles and CQB platforms, the BANISH Speed K provides a short, battle-ready suppressor with minimal tradeoffs in gas management. Check current availability and purchase details here: Check availability
