One of the most interesting but least talked about aspects of Maxim Defense is its suppressor wing, and they talked to about their almost spooky quiet GPMG can. 

While on a visit to Maxim's St. Cloud, Minnesota, headquarters, we were able to talk to CJ Dugan and the gang about the company's suppressor team. Acquired after the great schism in the suppressor industry in 2017, Maxim's quiet-time R&D crew includes such legends in the industry as Dr. Phil Dater

In 2019, the company arrived at SHOT Show with a few prototypes of their integrated suppressed AR uppers as well as a very interesting can for the FN MAG 58/M240 series of 7.62 NATO general-purpose machine guns. Incorporating a series of patent-pending technology, it is treading harsh terrain that has broken other cans.

Submitted to the Army for testing, the folks at the Maneuver Battle Lab at Fort Benning, Georgia really liked it after they shot it, as previous designs for the M240 just didn't hold up to the abuse of full-cyclic fire or perform their main mission: dropping the noise signature. 

“Some of them, they got way too hot and ... would glow red hot,” Ed Davis, director of the Battle Lab, told about the testing last November. “Some of them wouldn’t last very long; most of them really didn’t dampen the noise of any significance that was worthwhile.”

Maxim's suppressor in action, which they have dropped down to about 135dB, which is quiet enough to talk in the vicinity of without ear pro: 

As far as durability, the M240 prototype cans from Maxim have been outlasting the test barrels on the machine guns they have been using. 

We talk about the development of the can with Dugan, below.
