The Banish Thread Adapter, M14x1 LH to 5/8×24 (Banish part no. 100000310219) is made to adapt barrels with M14x1 left-hand muzzle threads to muzzle devices threaded 5/8×24 right-hand. Banish lists the thread size as M14x1LH to 5/8x24RH, so it is the piece to reach for when the barrel thread and the device thread do not match. The adapter is made in the USA from steel and finished in black oxide. It lets you use the wide range of 5/8×24 muzzle devices on a barrel that was not threaded for them.

Key Specifications

• The barrel side is M14x1 LH, a metric left-hand thread, so the direction matters when you match it to the barrel.
• The device side is 5/8×24 RH, the common right-hand pattern for muzzle devices.
• Construction is steel, a durable material for a threaded joint at the muzzle.
• The finish is black oxide, in black.
• It is made in the USA.
• It is classed as a thread adapter, not a muzzle device, so it needs a device on its 5/8×24 side.
