Professional Reticle Levelling System

The Wheeler Engineering Professional Reticle Levelling System (PRLS) is a precision tool and technique designed to allow a scope to be perfectly levelled on any firearm with ease. CNC machining, factory adjustment calibration set screws, anodized aluminium construction and a protective moulded case put the PRLS in a class of its own. The system is comprised of two machined aluminium level housings calibrated to their integrated levels. The Barrel Clamp Level is attached to the guns barrel while the smaller Reference Level is placed on scope base, bottom half of a ring or other flat surface perpendicular to the vertical axis of the gun. The gun is then rotated until the Reference Level is aligned. The tuning adjustment knob on the Barrel Clamp Level is then turned until its level is centred to match the Reference Level. At this point the Barrel Clamp Level is calibrated to the guns axis. The scope can be installed loosely and the Reference Level placed on top of the scopes turret cap. The scope is rotated until the Reference Level is aligned with the Barrel Clamp Level and then simply secured in place. The Wheeler PRLS is the most effective instrument available for precision scope alignment.
