Diamondback turned heads at SHOT Show 2026 by jumping into the suppressor business with the American-made Ventra line, and the DBS-22i is the compact rimfire entry of the family. Where most .22 cans lean on aluminum internals because rimfire is easy on parts, Diamondback built this one around an Inconel 718 core. That is the same nickel superalloy found in jet engine components, chosen for its ability to hold strength and shape under serious heat.
That material choice is what separates this can from the typical rimfire crowd. The Inconel core is why the DBS-22i carries a full-auto rating and stretches beyond .22 LR to handle 5.7x28mm, so it covers everything from a backyard plinker to a PS90 or Ruger-57. The exterior uses 17-4 stainless steel wrapped in Cerakote Armor Black, giving it real corrosion resistance and a finish that holds up to holster wear, range bags, and weather.
At 5.625 inches long, 1.125 inches in diameter, and just 5.8 ounces, it adds very little to the end of a barrel. The baffle geometry is tuned for an even, pleasant tone rather than a sharp crack, and it cuts muzzle flash noticeably on shorter hosts. The 1/2×28 direct thread mount fits the vast majority of threaded rimfire pistols and rifles out of the box, and Diamondback even machined the thread pitch right onto the can, a small touch that saves guesswork at the bench.
Every Ventra suppressor is CNC-machined and inspected at Diamondback's Florida facility for concentricity and structural integrity. The DBS-22i arrives as a single ready-to-mount unit with no assembly required, and routine upkeep is as simple as a soak in a quality suppressor solvent. For a first-generation rimfire can, Diamondback clearly did their homework, and the result is a tough little suppressor built to outlast the dirtiest ammo you can feed it.
It handles both. Diamondback rates the DBS-22i all the way up to 5.7x28mm thanks to its Inconel 718 core, so it pairs just as well with a PS90 or Ruger-57 as it does with a threaded 10/22 or Mark IV. It carries a full-auto rating too, so sustained fire is not a concern.
No, it is a sealed single-piece unit that does not disassemble. Diamondback designed it to be serviced by soaking in a dedicated suppressor solvent, which breaks down lead and carbon fouling without opening the can. A periodic soak after range sessions keeps it running like new.
If your barrel is threaded 1/2×28, which is the standard for nearly all threaded .22 pistols and rifles, it threads straight on with no adapters needed. Diamondback also machined the thread pitch marking directly onto the suppressor body, so there is never any question at the bench.
Most rimfire cans use aluminum baffles to save weight, but aluminum has limits with heat and harder-hitting rounds. Inconel 718 is an aerospace superalloy that keeps its strength at extreme temperatures, which is what lets the DBS-22i carry a full-auto rating and a 5.7x28mm rating. Even with the tougher material, it still weighs just 5.8 ounces.
