GSL TECHNOLOGY INC FAT MAN

GSL is Greg Latka’s shop — the man who built Gemtech’s legendary SMG cans — so the Fatman comes by its subgun pedigree honestly. Full-auto rated and built from aluminum and stainless, it packs a high-volume design into six inches and eleven ounces, pulling 34 dB off your MP5 or 9mm PCC. The HK three-lug mount is included, with thread adapters available if your host has other ideas. Designed for entry teams, ideal for backyard plinking.

Short, fat, and quiet — turns out you can have all three.
