The GrovTec Thread Converter (brand part no. GTHM197) is a one-piece black-oxide steel adapter that steps a 1/2-28 threaded barrel up to accept 5/8-24 threaded muzzle devices. Shooters who own a muzzle brake, flash hider, or other 5/8-24 device sized for a larger-diameter barrel can run it on a smaller 1/2-28 barrel without buying a second device in the smaller thread. GrovTec machines the converter from a single piece of steel and finishes it in black oxide to resist corrosion and match most muzzle hardware. It is a simple, direct way to standardize on one thread pitch across barrels of different diameters.
