Trek II
The TREK-II is a compact and rugged threadmount suppressor for 5.56MM rifles and is suitable for full auto and shorter barrel (10.3″ or greater) carbines. The TREK-II is made of rugged 17-4 stainless steel, with non-welded construction. New design allows for easy pinning to 11″ or longer barrels to meet non-SBR overall length requirements.
