The MK13 platform is a popular rifle among collectors.  The Knight Armament suppressors are unique, and machining a barrel to retain them properly demands careful machine work.

We've answered that need through automation.  LRI has developed a cutting-edge process that adapts to the manufacturing variances common to the MK11 suppressor.  We precisely locate the registration pin and milled slots on the barrel to ensure that the suppressor purchases concentric to the bore with no "rattle."  Doing so ensures the platform delivers the accuracy expected of a precision rifle.

Note:

This is a service that requires you to send us your suppressor.  Due to the manufacturing variances common to the product, LRI will not perform this service without it.
