LaRue LT659 QD Mount Features The Larue Tactical LT659 is purpose built for the CompM4 and CompM4-S optics matching the exact mounting interface those sights use rather than relying on a generic clamp. The mount s locking LaRue Speed Lever is the centerpiece of the design letting the shooter detach the optic and reinstall it later while returning to the same point of impact. LaRue Tactical guarantees this return to zero performance which matters for anyone who needs to remove an optic for storage transport or backup iron sight use. Assembly and zero confirmation take only a few minutes before the rifle is ready for the range. Machined from bar stock aluminum rather than cast or stamped material the LT659 holds tighter tolerances that translate directly into a more secure repeatable lock up under recoil. The matte black anodized finish resists glare and wear keeping the mount durable through hard use. At a 1.9 inch overall height and 1.73 inch mount height the LT659 sets the optic at a practical sight height for most AR15 M16 and M4 pattern uppers. The mount ships complete with replacement screws a QD adjustment wrench thread locker and instructions giving the shooter everything needed for install without hunting down extra hardware and it is available for sale at GrabAGun.
