The H7.

The Spectrum Defense Helikil H7 is our flagship .30 Caliber Suppressor. Utilizing our patented Helikil baffle design, the H7 brings a balance to the table when it comes decibel reduction and low back pressure performance. The H7 is crafted from Inconel 718, which as a material features superior strength at extreme temperatures. Because of this, the H7 is Full Auto Rated and has no barrel length restrictions (Within reason, IDK if a 8″ 300 Win Mag would work). Using 1.375 x 24 (HUB) mounts, the H7 can be configured to run on almost any platform.
