GrovTec GTHM371 HUB Direct Thread Suppressor Adapter 5/8x24 - Black Nitride Stainless Steel

The GrovTec GTHM371 HUB Direct Thread Suppressor Adapter lets shooters mount a 1.375"x24 HUB-compatible suppressor on any barrel threaded 5/8x24 - the standard muzzle thread pitch used on .308 Winchester / 7.62 NATO rifle barrels.

Cut from a single piece of stainless steel and finished in a low-glare black nitride coating, the adapter uses a low-profile, flush-mounting design so the suppressor hugs the muzzle without adding excess length or snag points. The one-piece stainless construction resists galling and corrosion through repeated suppressor use.

Threading is simple: spin the HUB suppressor onto the adapter's 1.375"x24 male mount and then thread the assembly directly onto the host barrel's 5/8x24 muzzle. The GTHM371 is a clean mounting option for shooters who prefer the security and accuracy of a direct-thread fit over a quick-detach system on a 5/8x24 threaded host firearm.
