The GSL Fatman suppressor is a full auto-rated, aircraft grade aluminum suppressor that is built to handle your favorite MP5 or Three-Lug Barrel submachine guns. Perfect for the coming Christmas season, the jolly fatman will bless your MP5 and 9mm PCCs for years to come.

The Fatman is an “Entry Suppressor” designed for LEO teams and building clears to navigate quickly through urban environments…Its also perfect for your backyard plinking, and your daily carry MP5 backpack gun. It rocks an incredible sound reduction of 34dB and our updated baffle system.

The Fatman is a non- user serviceable suppressor and mounts with the HK Spec trilug mount system.

GSL Fatman is rated for 9mm PCCs, and 38spc rifles, and 357 rifles, and (300blk-subsonic rounds only)

The GSL Fatman is a flexible platform that now allows for a variety of interchangeable mounting options.

The trilock mount for the H&K trilug is included with the Fatman, and these additional mount options include:
1/2×28, 1/2×36, 5/8×24, 9/16×24, Scorpion 18mm, UZI FS, and the included MP5 trilug

The Fatman installed over the factory knurled thread protectors often does not clear the mount…
We recommend a smooth thread protector, and have these available for sale also HERE.
