The Noveske thread protector in 1/2×28 (brand part no. 05000339) covers the muzzle threads of a barrel when no suppressor or other muzzle device is mounted. Noveske lists the same protector in 5/8×24 as well, so this is the 1/2×28 pitch, the one used on the muzzle of most AR-15 style barrels. A bare thread takes the first knock in a case, a truck or a range bag, and a protector keeps the damage off the threads you need for a suppressor later. It is a small, simple part that is worth having on any threaded barrel.

Key Specifications

• The thread pitch is 1/2×28, a common muzzle thread for AR-15 style barrels.
• It protects the barrel’s threads when you run the rifle without a suppressor or muzzle device.
• Noveske also lists a 5/8×24 thread protector, so check the pitch before you order.
