The Griffin Armament Sportsman UL 46 HD FDE suppressor is engineered as a lightweight yet highly durable option for hunters and shooters who demand consistent performance. Built from 17-4 H900 stainless steel with a tubeless laser-welded design, it delivers near-titanium weight while standing up to extended strings of fire far better than earlier aluminum Sportsman models. Its flat dark earth finish and compact 6.25" length make it a streamlined, unobtrusive addition to your .46 caliber rifle or compatible .45 caliber tilt-barrel pistol when paired with the appropriate HUB mount or Nielsen device.

This model is purpose-built for hunting and general range use, offering excellent sound reduction without adding excessive bulk to the muzzle. The patented Eco-Flow baffle system helps reduce gas blowback and improve function on gas-operated hosts, making it a practical choice for modern semi-automatic rifles. With industry-standard 1.375"x24 HUB rear threading and full-auto rating, the Sportsman UL 46 HD FDE provides versatile mounting options and confidence for high-volume practice or training sessions. It reflects Griffin Armament’s reputation for thoughtful engineering, robust construction, and user-focused innovation.
