The KBA Custom precision shoulder Ring is designed for the Tavor SAR rifle. The factory shoulder available on the Tavor is undersized, and the existing threads are too long for most muzzle devices. In addition, the factory check-nut that is provided with the rifle is known to cause alignment issues if used to support suppressors or their muzzle devices (due to the check-nut not having parallel faces).
This Ring slips over the existing muzzle threads and increases the size of the shoulder by precisely bearing against the small factory shoulder. It also reduces the length of the muzzle threads to 0.60”, allowing any device or suppressor to be properly mounted. Shim kits and 1/2” peel washers can also be used to properly index muzzle brakes.
This Ring can be used on the factory 5.56 barrel, or the Tavor’s 9mm conversion barrel.
It can also be used as a spacer ring as needed on any barrel with standard ½” muzzle threads, and a barrel OD of approximately 0.590”. The thickness of this Ring is 0.128”. Made of heat treated 17-4PH stainless steel and precision machined and finished to within 0.0005”, it provides a full size mounting face (OD = 0.750”) for your muzzle device/adapter/mount. It is Melonite coated in black.
Made in the USA.
