Gemtech's new Tracker is the first suppressor made specifically with the hunter in mind. At 11 ounces it doesn't add bulk to the already weight conscious hunter and only adds a little over 7 inches to the overall length of the rifle once threaded on the barrel. You can still stalk your prey without getting hung up on the brush and low hanging trees. The Tracker is suitable for most major hunting calibers and is adaptable to most rifles. Hunting with the Tracker offers hearing protection improved accuracy faster follow up shots and best of all won't panic wild game. - Don't kill your hearing kill your dinner. - Caliber: Multiple see below* - Sound Reduction: 27 dB (At the shooter) - Length: 7.9 - Diameter: 1.6 - Weight: 11.3 oz. - Materials: Titanium and Aluminum - Finish: Hard Coat Black Anodize - Mount: 5/8-24 (2A) Thread - For Barrels: - 24 or longer 300WM - 16 or longer 7.62x51/.308 WIN - 16 or longer 5.56x45/.223 - 7.5 or longer 300 BLK
