Suppressor Mounting Systems 2026: HUB, KeyMo, ASR & SOCOM Compared

Which Suppressor Mount Should You Buy?

Buy the ecosystem, not the brake. If one can will serve several rifles, the Dead Air KeyMo system is the best all-around quick-detach: host devices run under $90, the lockup is one-handed and repeatable, and the KeyMo Omega adapter brings any HUB 1.375x24 can onto the pattern. Already own SilencerCo cans? The SilencerCo ASR brake is the native QD and the best value. Building a duty or full-auto rifle where lockup durability outranks flexibility? SureFire SOCOM Fast-Attach is the toughest interface in the industry, with the tradeoff that it deliberately rejects HUB and stays a closed system. Running a single precision host? Direct thread is the lightest, shortest, and most repeatable option. Everyone else lands on a HUB can plus the adapter for whichever QD pattern their host devices use.

The sections below break down each ecosystem, the host device you thread onto the barrel, and the lock-in cost of committing to it. If you are still deciding which can to register first, our suppressor buying guide ranks cans by caliber and budget, and the multi-caliber suppressor guide covers the HUB cans that run the widest range of mounts.

The HUB Standard Changed Everything

A HUB-threaded suppressor is never married to one brand's QD system for life, which is what makes the standard the single most important fact in mount selection. HUB is the 1.375x24 thread standard on the rear of the can. SilencerCo popularized the standard with the Omega 300, and Dead Air, Rugged, YHM, and most modern makers now ship HUB rear threads. That rear interface accepts an adapter for nearly any pattern, so the same registered tube can move between KeyMo, Plan-B, Xeno, and direct thread as your host list grows.

The practical upshot is that adapters, not cans, set your flexibility ceiling. The Dead Air KeyMo Omega adapter threads onto any HUB can and adds the KeyMo quick-detach interface. The Rearden Atlas Bravo adapter converts a HUB can to the Plan-B taper mount in about 0.400 inches of added length. Buy a HUB can and one adapter, and you have bought into an open system instead of a brand's walled garden.

Direct Thread vs Quick-Detach: The Core Tradeoff

Direct thread wins on weight, length, and repeatability; QD wins on speed and multi-host flexibility. Direct thread screws the can straight onto the barrel threads (1/2x28 for 5.56, 5/8x24 for .30 cal) with no intermediate interface to introduce play, which is why a single precision bolt gun or a dedicated rimfire host is usually direct thread. The cost is time: pulling a direct-thread can to move it to another rifle means unscrewing several turns against carbon-fouled threads.

Quick-detach trades a little length and weight, plus the price of a host device on every rifle, for can swaps measured in seconds and repeatable indexing back to zero. The SilencerCo Omega 300 is the can that makes this concrete: it ships with a 5/8x24 Bravo direct-thread mount, accepts the ASR QD interface, covers 5.56 NATO through .300 Win Mag on one tube, and is the can that pushed HUB 1.375x24 into an industry standard. The decision is rarely ideological. It is a count: one host favors direct thread, several hosts favor QD.

SureFire SOCOM Fast-Attach

SOCOM Fast-Attach is the toughest QD lockup on the market and the most closed ecosystem. The mount uses a ratcheting interface on a SureFire muzzle device that indexes hard against the shoulder, and it has the military service history to back the durability claim. The catch is deliberate: SureFire does not use HUB, so a SOCOM can cannot adapt to KeyMo, Xeno, ASR, or Plan-B. You are buying into SureFire for the life of the can, which is the right call for duty and full-auto hosts where lockup durability outranks flexibility.

Dead Air KeyMo and Xeno

KeyMo is the best all-around QD ecosystem, and Xeno is Dead Air's lighter modern follow-up. KeyMo uses a taper interface with one-handed operation and strong, repeatable lockup; the host brake or flash hider runs under $90, and the KeyMo Omega adapter opens the pattern to any HUB can. Xeno is the newer taper mount, among the lightest current systems, with left-hand threads that fight the carbon lock that can seize a can onto a device. Pick KeyMo for the mature ecosystem and the widest device selection; pick Xeno when weight and anti-carbon-lock matter more than host breadth. Both still require a matching Dead Air device on every host you want to share the can across.

SilencerCo ASR (Active Spring Retention)

ASR is SilencerCo's native QD and the best value if you already own SilencerCo cans. A spring-tensioned locking collar gives one-hand-on, one-hand-off attachment with no rotation while firing, and the host brake runs about $80 in a wide range of thread pitches. The detail that trips buyers is the mount variant: the can-side ASR mount comes in Alpha, Bravo, and Charlie sizes matched to specific SilencerCo cans, so confirm which your can takes before ordering. The SilencerCo Hybrid 46M is the broadest expression of the system: it ships with a Charlie ASR mount and also accepts direct-thread, 3-lug, and piston mounts, covering 9mm through .338 Lapua Magnum on one registered tube.

Q Plan-B and the Rearden Atlas Taper Mount

Plan-B is the open taper-mount ecosystem, and the Rearden Atlas is how a HUB can joins it. The Q Cherry Bomb is the original Plan-B taper device: 360 degree ports mean no timing and no shims at install, it weighs about 2 oz, and it indexes with excellent repeatability. The Rearden Atlas Bravo adapter converts a HUB 1.375x24 can to the Plan-B taper in 17-4 stainless at roughly 2.15 oz, adding only about 0.400 inches of length. The ecosystem spans devices from Q, Dead Air, Rearden, and others, which is why Plan-B is the cross-host pick for shooters who want one can to roam a whole rack.

HUXWRX Torque Lock and Flow-Through

Torque Lock is the self-tightening QD built around HUXWRX flow-through cans. The patented interface uses left-hand threads that tighten with each shot rather than working loose, and the host is a flash hider, so the rifle keeps flash suppression with the can removed. The HUXWRX FLOW 556 Ti is the anchor can for this system: 100 percent DMLS Grade 5 titanium at 11.4 oz, full-auto rated, with no minimum barrel length, and a flow-through design that pushes gas forward instead of back toward the shooter. The tradeoff is that Torque Lock is proprietary and the flow-through design carries a visible flash signature, so this is a system for shooters who prioritize low blowback on a QD interface.

Mounting Systems Side by Side

The fastest way to choose is to read the lock-in column. Open systems (HUB direct thread, Plan-B, KeyMo and Xeno via HUB adapters, ASR on HUB cans) keep your options live; closed systems (SureFire SOCOM, HUXWRX Torque Lock) trade that flexibility for a specific durability or gas-management edge. The seven systems here cover the vast majority of hosts; uncommon thread pitches and bore sizes live in the catalog.
