The Dead Air CT5P Patrol suppressor is a compact 5.56 NATO can built for semi-automatic duty rifles, and this configuration pairs a 1/2×28 direct-thread mount with a Flat Dark Earth high-temperature Cerakote finish (Dead Air part no. CT5PDTFDE0528). Dead Air designed it around a compact Triskelion baffle stack and its Gas Management System, which together cut the backpressure and fumes that reach the shooter on a direct-impingement or piston AR. The company left off the HUB feature used on its larger cans to keep the CT5P short and light, with minimal point-of-impact shift. It is made from Haynes 282 alloy using additive manufacturing and has been tested to the SOCOM SURG standard. For a patrol carbine, a short AR build or a 6mm ARC rifle, it is a light can that changes very little about how the rifle runs.

Key Specifications

• Caliber rating is 5.56 NATO and 6mm ARC, the two cartridges Dead Air tuned the CT5P to run with minimal change to bolt velocity.
• The mount is a 1/2×28 direct thread, so the can threads straight onto the most common 5.56 AR muzzle thread.
• Length is 5.49 inches in the direct-thread configuration, short enough to keep a carbine handy in a vehicle or a doorway.
• Weight is 13.7 ounces in the direct-thread configuration, light for a can rated for duty use.
• Diameter is 1.6 inches, the same across Dead Air’s direct-thread, Xeno and KeyMo versions.
• Construction is Haynes 282 alloy, a high-temperature material built up with additive manufacturing.
• The finish is Flat Dark Earth high-temperature Cerakote, and the shaped exterior adds surface area that sheds heat and cuts glare.
• Bore diameter is 6mm, sized for the 5.56 and 6mm ARC bullets the can is rated for.
• The energy rating is 2,200 ft-lbs, the ceiling Dead Air sets for loads run through it.
• It is full-auto rated for both 5.56 NATO and 6mm ARC, so sustained strings of fire are within its design limits.

Frequently Asked Questions

Will the CT5P work on a short barrel? Yes. Dead Air lists no minimum barrel length restriction, and says the CT5P cuts muzzle flash and spark to near-undetectable levels on 5.56 NATO rifles with barrels as short as 10.5 inches.

Do I need ATF approval to buy this? No. As of October 9, 2026, ATF no longer requires Form 4 approval, registration or a tax stamp for suppressors. It transfers on a Form 4473 with a background check through a Class 3 (SOT) dealer. State and local laws still apply.

Does it run on 6mm ARC as well as 5.56? Yes. Dead Air rates it for 5.56 NATO and 6mm ARC, including full-auto fire, and says it works with minimal change to bolt velocity on both direct impingement and piston gas systems.
