The KOVIX T1-300 8-inch suppressor OD Green is a laser-welded, 100 percent titanium suppressor from KOVIX, rated for .308 Win, .300 Win Mag and .300 RUM. The 8-inch T1-300 is the longer of the two T1-300 lengths, the one Kovix says favors maximum sound reduction. The body measures 8.35 inches long by 1.72 inches in diameter, and Kovix lists no barrel length restrictions. Both a 5/8-24 and a 1/2-28 thread adapter come in the box, and the can also accepts HUB mounts for quick attachment. This one is finished in OD Green.
