GrovTec GTHM243 Muzzle Thread Protector 1/2-28 x .920" for Ruger 10/22 Bull Barrel

The GrovTec GTHM243 is a dedicated 1/2-28 muzzle thread protector built specifically for the Ruger 10/22 bull barrel. It shields the factory threads on your barrel crown from dirt, moisture, and handling damage whenever a suppressor, flash hider, or compensator is not installed, keeping the muzzle ready for the next muzzle device.

With an outside diameter of .920", this protector is sized for the larger-diameter bull barrel profile rather than the standard 10/22 barrel. It threads on with the standard 1/2" x 28 pitch used on threaded .22 LR barrels, seating cleanly against the muzzle for a low-profile finished look.

The GTHM243 is machined from quality steel and finished in a durable black-oxide coating that resists corrosion and stands up to repeated installation and removal without galling the threads. Like the rest of the GrovTec muzzle accessory line, the GTHM243 is made in the USA to tight dimensional tolerances for a precise fit on your Ruger 10/22 bull barrel.
