Best 5.7x28mm Suppressors 2026: Pistol & PS90 Picks

Nine of the eleven cans here thread on with a standard 1/2x28 direct-thread setup, so the only question that matters is whether your host presents that thread. The two exceptions sit at either end of the list: the Omega 36M ships on SilencerCo's Charlie ASR system and needs the optional Charlie 1/2x28 direct-thread mount to run that way, and the GSL P-90 is 12x1 LH Bi-Lock only. Two current 5.7 pistols present 1/2x28 from the factory: the threaded Smith & Wesson M&P 5.7 and the threaded PSA 5.7 Rock. The Ruger-57 gets there through Ruger's drop-in threaded-barrel kit. Every current FN Five-seveN MRD ships unthreaded, so it is the longest path here: an aftermarket M10x1.0 RH threaded barrel first, then an M10x1-to-1/2x28 adapter before a standard can will start.

Price the barrel before you price the can on a Five-seveN. M10x1.0 RH is the aftermarket standard for that pistol, and a barrel plus an M10x1-to-1/2x28 adapter is what turns it into a normal 1/2x28 host. Neither part changes the suppressor's own rating, so a can that is not listed for 5.7x28 stays off the gun no matter how well the threads match. If you are still choosing the pistol itself, our best 5.7x28mm pistols guide covers which models ship threaded and which need barrel work first.

The PS90 is its own case. Neither the PS90 nor the P90 presents an exposed 1/2x28 thread from the factory, so putting one of the 1/2x28 cans here on a PS90 means fitting a threaded barrel or a threaded barrel shroud that exposes standard threads. That is a real project, not a bolt-on, and it is worth pricing before you file a Form 4 against a can the gun cannot currently accept.

Most 5.7 suppressors are rimfire cans that happen to carry a 5.7x28 rating, and that is fine as long as the manufacturer states the rating explicitly. The bore diameter is the easy part. The hard part is pressure and heat: 5.7x28 is a bottlenecked centerfire cartridge that drives a 40gr bullet at 1,700 to 1,810 fps from a pistol, so the blast baffle takes a beating that .22 LR never delivers. That is why the ratings are model-specific and why "it is a .22 can, so it will handle 5.7" is the wrong instinct.

The Gemtech NEBULA 5.7 is the purpose-built 5.7 design here that mounts to ordinary threaded hosts, engineered around the cartridge from the start. Gemtech prints the core from 6Al4V titanium, which lets them shape internal geometry for 5.7 gas volume rather than inheriting a rimfire baffle stack, then reinforces the high-pressure end with a 17-4PH stainless tube and a stainless blast baffle. The mount is removable, shipping as 1/2x28 direct thread with a Plan B mount interface that accepts Plan B-style muzzle devices. At $549 it costs more than the rimfire-format cans and, at 7.1 in and 9 oz, it is bigger than all of them except the dedicated P90 can.

The rimfire-format picks earn their place on weight and serviceability. The $399 Flow 22 Ti is the lightest fixed-length can here at 3.9 oz and vents gas forward, which matters most on the delayed-blowback FN Five-seveN and the straight-blowback PS90, where a can that dams gas sends it back through the action. The $426.99 Mask HD packs a serviceable 17-4 stainless stack into a 5.1-inch titanium-tube body, the shortest titanium-tube body in the ranking. The Tactical Solutions AXIOM solves the specific failure that ends dual-duty cans, a fouled core seized into its tube, with a split-tube housing that opens instead of fighting you. If .22 LR is actually your primary host and 5.7 is the occasional guest, our best .22 LR suppressors guide ranks the wider rimfire field on cleaning and sound instead.

One more distinction is worth internalizing before you spend: serviceable versus sealed. The AXIOM, Mask HD, Oculus 22, Sparrow 22, Switchback 22, Banish 22, and Phantom 22 all come apart. The Flow 22 Ti and the Omega 36M do not, and the GSL P-90 is not user-serviceable either. If the can will ever see .22 LR, take the serviceable design, because unjacketed lead over dirty powder is what actually kills suppressors in this size class.

Two fine-print limits decide more 5.7 purchases than sound numbers do, and the first one is barrel length. Yankee Hill Machine requires a 10-inch minimum barrel for 5.7x28 on the Phantom 22. That single line removes every ordinary 5.7 pistol from consideration, because the M&P 5.7, the PSA 5.7 Rock, the Ruger-57, and the Five-seveN all run barrels around 5 inches. On a PS90 or another 5.7 carbine that clears 10 inches, the Phantom 22 is a genuinely good 4 oz value. On a pistol it is the wrong purchase, no matter how the caliber list reads.

The rest of the field is cleaner. HUXWRX, Dead Air, and Rugged all state no barrel-length restriction on their 5.7-rated models, which is why the Flow 22 Ti, the Mask HD, and the Oculus 22 are the simplest choices for a threaded pistol. That is worth real money if you own more than one 5.7 host, since it means the same registered can moves from a 5-inch pistol to a 16-inch carbine without a compatibility check each time.

Full-auto ratings are the second limit, and they are more specific than the marketing suggests, because approving a caliber and approving full-auto fire in that caliber are two separate statements. The SilencerCo Sparrow 22 and the Banish 22 both pass 5.7x28, but both limit full-auto fire to .22 LR, so treat them as semi-auto 5.7 cans. YHM does not state a 5.7 full-auto rating on the current Phantom 22 page. The Flow 22 Ti, NEBULA 5.7, Mask HD, AXIOM, Switchback 22, Oculus 22, Omega 36M, and GSL P-90 all carry full-auto ratings that cover the 5.7 use case. None of this matters for a semi-auto range gun, and all of it matters if the can rides a registered transferable or a rental counter.

Ammunition changes what you hear more than the can does. Standard 5.7 loads are supersonic by a wide margin, so a ballistic crack stays in the equation at every host length, and the suppressor is working on muzzle blast rather than the projectile. Our best 5.7x28mm ammo guide breaks down the current FN loads and the velocity spread between pistol and PS90 barrels, which is the number that actually sets your expectations for a suppressed 5.7.

The federal making and transfer tax on a suppressor is $0 under the One Big Beautiful Bill Act, the lowest federal tax burden on one since the National Firearms Act took effect in 1934. The tax is the only thing that went away. You still file an ATF Form 4 through a dealer, submit fingerprints and a photo, notify your chief law enforcement officer, pass a NICS background check, and end up with a registered NFA item. Current eForm 4 approvals commonly run from a few days to a couple of weeks, so the paperwork is no longer the thing that decides whether the purchase is worth it.

Suppressors are legal to own in 42 states. Ownership is banned in California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, Rhode Island, and the District of Columbia, and Connecticut allows ownership while prohibiting suppressor use for hunting. Confirm your own state before you put money down, because the federal tax change did nothing to state law. For the full Form 4 walkthrough, trust versus individual filing, and what a dealer actually does for you, start with our how to buy a suppressor guide, and use the broader suppressor buying guide when you are weighing calibers, mounts, and backpressure across more than one host.

One planning note specific to 5.7: pick the host before you pick the can, since a Form 4 takes days but a threaded barrel or a barrel shroud can take longer to source. Drop a threaded 5.7 host into the builder to see which of these cans the thread filter clears for your setup, or browse the full suppressor lineup in the catalog to compare against 9mm and rimfire options side by side.
