CAT BEN SUPPRESSOR - 3.9 OZ TITANIUM .22 LR RIMFIRE SILENCER, .22 LR TO 5.7X28
The CAT BEN (CAT/BEN, or colloquially known as the CAT Benowitz) is a compact titanium .22 LR rimfire suppressor from Combat Application Technologies, optimized for .22 LR pistols and rifles and rated up to 5.7x28mm. Additively manufactured as a one-piece suppressor, the BEN measures 4.30" long and 1.28" in diameter, weighs 3.9 oz, and threads directly onto 1/2x28 barrels. It uses CAT's DiVerge technology, is optimized for a velocity window of 750 to 1,200 ft/s, and wears a DLC finish.
CAT built the BEN for bolt action and semi-auto firearms, with no barrel length restrictions on .22 LR as long as your projectile is properly stabilized. That makes it a natural fit for everything from a short-barreled .22 pistol to a full-length rimfire rifle. In PEW Science testing on a Beretta 21A subcompact pistol with a 2.4" barrel, the BEN earned a composite Suppression Rating of 79.6.
The BEN can also run 5.7x28mm, though CAT notes that cartridge is not what the can is optimized for and recommends keeping rates of fire low. If you're comparing CAT's rimfire options, take a look at the CAT SR A2, or browse our full lineup of CAT suppressors.
CAPITOL ARMORY'S OPINION
The BEN is all about packing serious rimfire suppression into a really small package. At 4.30" long and 3.9 oz, it won't add much bulk to a .22 pistol, and it's just as at home on a bolt action or semi-auto rifle at the range or out in the field. Since CAT doesn't put any barrel length restrictions on it for .22 LR, you don't have to think twice about which host it goes on.
The one-piece titanium build keeps it light and simple, and the trade-off is that you won't be taking it apart to clean it. Plan on soaking it every 2,000 to 4,000 rounds to keep lead buildup in check. You'll also notice some white sparking early on, which is normal for titanium and tapers off with use.
Being able to run 5.7x28 is a nice bonus, but we'd treat it as just that. The BEN is a .22 LR can first, so if 5.7 is going to be your main cartridge, keep your strings slow and let it cool between them.
