5/8″-24TPI thread adapter for M14

Description

Improved thread adapter for the M14.  It converts the 19/32″-32TPI muzzle threads to a 5/8″-24, suitable for mounting a suppressor.

This redesigned adapter has several distinct advantages versus other products on the market:

• The internal geometry has a counter-bored recess in the front that is only a few thousandths bigger diameter than the tip of the barrel, so this assures the adapter is concentric to the barrel.
• The adapter has the bottom of the counter-bore seat on the crown of the barrel, assuring the adapter is parallel to the bore.
• The adapter can be used alone, without a front sight, for people who are going to scope their rifle.  This design eliminates the complexity of needing splines to time the front sight to the rifle, or needing the castle nut to hold it on.  Machining splines and square holes is an expensive process, requiring broaching or Wire EDM machining, so this design is a highly effective, low cost solution to adaping threads for suppressor mounts, or other muzzle devices.
• The adapter can also be used with a front sight we designed to go with it (sold separately).  Exactly to eliminate the need for splines and castle nuts to time the sight, in order to set mechanical zero by sliding the front sight left-right, this much simplified design sets mechanical zero by allowing the front sight to rotate about the adapter.
