The ThunderCan Azimuth GRT is a 5.56×45 suppressor from Shaw Armament Systems, 3D-printed as one monolithic piece from Inconel 625 and finished in black high-temperature Cerakote. It uses Shaw’s patented Gas Reduction Technology, a coaxial blast chamber that vents gas into a secondary outer path to cut backpressure and gas blowback. A forward-venting front cap sends gas away from the shooter instead of back toward the action. The maker designed it for sustained fire and rates it for belt-fed platforms, with no barrel length restrictions. That makes it a duty-grade can for everything from a short-barreled AR to a heavy 5.56 gun.

Key Specifications

• Overall length is 6.8 inches, compact enough for short-barreled carbines.
• Weight is 16.3 ounces without the mount, a fair figure for an all-Inconel can.
• The caliber is 5.56×45, the standard AR-15 and M4 chambering.
• Construction is monolithic 3D-printed Inconel 625, chosen for heat resistance and durability under sustained fire.
• The mounting is HUB compatible with a 1/2×28 direct-thread mount included, so it fits a standard AR muzzle thread out of the box.
