How does the enhancer attach and work — 1 Answer

Here are the mounting instructions:

1. Slide the precision mount portion of the Enhancer onto the end of your scope tube, align to horizontal, and tighten mount screws evenly to 15 IN LB., or just snug. This is secure enough to remain perfectly stationary through high recoil and abusive handling.
2. Adjust the Enhancer's elevation and windage screws to achieve the same zero as your riflescope, as the initial installation of the Enhancer may change your existing point of impact. Zeroing may be done by shooting your rifle and sighting in as with any newly mounted optic, utilizing only the Enhancer's own elevation and windage adjustments. A laser boresight may facilitate this. The graduations around the adjustment dials represent 4 MOA, or 4 inches at 100 yards. Remember, your existing riflescope's zero never needs to be touched. An additional locking turret screw is utilized on the Enhancer to ensure solid adjustments through recoil and handling abuse. Loosen the screw before adjusting the turrets and lock before shooting. This locking screw takes very minimal pressure. Do not overtighten.
3. Confirm the same zero by shooting with the Enhancer installed as well as removed.
4. You may consider using your Enhancer with a second zero, or an "Enhanced" zero. Some users sight in their Enhancer a bit high to compensate for longer trajectories.
