GrovTec GTHM370 HUB Direct Thread Suppressor Adaptor 1/2x28 - Black Nitride

The GrovTec GTHM370 HUB Direct Thread Suppressor Adaptor lets you mount any 1.375"x24 HUB-compatible suppressor directly to a barrel threaded 1/2x28, skipping the quick-detach mount when a low-profile, no-fuss setup is preferred. The adaptor is machined from one-piece stainless steel with a corrosion-resistant black nitride finish, and the flush-mount design keeps added length at the muzzle to a minimum.

This is the 1/2x28 version of GrovTec's HUB direct-thread adaptor line, the standard thread pitch for 223 Remington / 5.56 NATO barrels and other centerfire rifles sharing that pattern. The HUB side uses the industry-standard 1.375"x24 interface shared by the majority of modern suppressors, so it drops straight into an existing suppressor collection without proprietary hardware. Thread the adaptor onto a clean, properly timed muzzle and hand-tighten the suppressor until snug - no special tools required.

Whether you're running a short-barreled carbine where every fraction of an inch matters or simply want a streamlined, repeatable mounting option for the range, the GTHM370 gives you a durable direct-thread solution backed by GrovTec's reputation for hard-use shooting accessories.
