CAT DD

CAT DD SUPPRESSOR - COMPACT 7.62 NATO RECCE SILENCER FOR AR-10 AND .308 RIFLES, HUB OR QD

The CAT DD (CAT/DD, sometimes called the Dirty Dave) is a compact 7.62 NATO suppressor from Combat Application Technologies, built for recce rifles and short-barreled .308 battle rifles. It uses CAT's Surge Bypass technology, measures 1.60" in diameter, and comes in titanium or Inconel 718 with a DLC finish. The HUB models measure 5.75" long and weigh 9 oz in titanium or 16.6 oz in Inconel 718. The QD models measure 6.1" long, weigh 9.8 oz in titanium or 17.9 oz in Inconel 718, and ship with a CAT Spooky 1 muzzle device.

CAT designed the DD for 7.62x51mm assault and reconnaissance platforms, optimizing it around a 13" SIG MCX-Spear and a velocity of 2,900 ft/s. That makes it a natural fit for AR-10 pattern rifles, DMRs, and other .308 battle rifles. CAT built the DD to reduce recoil and muzzle rise, keep toxic fumes to single digits, and limit blast propagation so it's easier for a team to communicate. It's designed specifically for the .308 Win cartridge and is not intended for loads pushing past 3,200 ft/s. In PEW Science testing on a 20" Savage Model 10 .308, the Inconel 718 QD model earned a composite Suppression Rating of 32.6.

The Inconel 718 models are CAT's "duty" focused option, able to support full auto or high rates of fire, and can run on 7.62 NATO barrels as short as 13". The titanium models cut the weight roughly in half and are built for lower rates of fire on barrels 16" and longer. HUB models ship without a mount, so you can pair them with any HUB (1.375x24) compatible mount. Comparing CAT's .30 cal options? The CAT AKB is a .30 cal generalist, and the CAT JL is a 7.62 NATO precision rifle suppressor. You can also browse our full lineup of CAT suppressors.

CAPITOL ARMORY'S OPINION

The DD is about as short as a serious 7.62 can gets. At under 6" on the HUB models, it keeps a short .308 handy, and CAT built it for exactly that kind of rifle: think a 13" MCX-Spear, a short AR-10, or a DMR you actually want to carry and maneuver. Short 7.62 cans can be loud, gassy, and rough to shoot, and CAT's Surge Bypass technology is aimed squarely at those problems. CAT also designed it to cut down on fumes and blast, which you'll appreciate if you're shooting alongside other people.

Picking a material comes down to how hard you run it. The Inconel 718 versions are the duty pick. CAT says they can handle full auto or high rates of fire, they work on barrels down to 13", and Inconel doesn't throw the white sparking you get with titanium. The titanium versions come in at roughly half the weight, which makes a lot of sense on a lighter precision or hunting build, but you'll need at least a 16" barrel and CAT wants you to keep the pace slow.

Mounting is flexible too. The HUB versions work with whatever HUB mount you already run, and the QD versions come ready to go with a Spooky 1. Just stick with compact muzzle devices if you're putting a QD mount on a HUB model, since the blast baffle depth doesn't leave room for some full-size devices.
