Fits the new-style Leonidas lock ring. 3d printed in strong resin, this part allows you to remove the lock ring in the event that it’s become locked onto the rifle through carbon fouling. If the heavy knurling around the outside doesn’t give you enough purchase to loosen it, the 1/2″ square drive in the center allows for use of a torque wrench or breaker bar for leverage.

If you have an old style knurled lock ring, we also offer a combo deal that includes both the wrench and an updated lock ring to replace your old one! This is a great value for the end user and allows this part to be upgraded without the need to send the upper back to us.

Part is rated for no more than 30 ft-lbs of torque for loosening, and tightening should only be done hand-tight at most. Square drive is not for tightening, and over torquing the lock ring may damage silencer components.

If ordering the combo deal, we must receive shipment of the old lock ring prior to shipping out your replacement. This is to comply with ATF regulations. Feel free to call or email us with any questions you have.
