GrovTec GTHM246 1/2-28 Muzzle Thread Protector - AR-15 Pencil Barrel Steel Black Oxide

Protect your AR-15 pencil barrel threads with the GrovTec GTHM246 muzzle thread protector. Purpose-built for the slim contours of a pencil barrel profile, this compact thread protector installs directly on your rifle's muzzle to shield the threads whenever the gun is run without a muzzle brake, flash hider, or suppressor attached.

The GTHM246 is machined from a single piece of steel and given a black-oxide finish for corrosion resistance and a low-reflectivity surface. A knurled exterior provides positive grip for easy hand installation and removal with no specialty tools required. With an outside diameter of .620" and a length of .637", the protector sits low and flush on pencil-profile barrels without interfering with handling or sight picture.

Whether you swap muzzle devices frequently or simply want to keep your factory threads clean and protected during storage and transport, the GrovTec GTHM246 is a focused 1/2-28 thread protector for any AR-15 platform rifle set up with a pencil barrel profile.
