Working in the technical services department at Warne, we often get asked if our quick detach rings really do return to zero after the scope is removed and reinstalled.  Since we guarantee they do, of course we say yes, but what if a customer wanted more proof than our word?  We decided to shoot a video where we take a brand new Remington 700 in .243 Win, using a GRS rifle stock, and Minox scope, we put our Maxima Quick Detach weaver style scope rings to the test.  While many shooters can product much smaller shot group sizes, the video was shot fast and continuous to ensure that no doctoring or editing was done to clean up any mistakes, what you see if what you get.  In this case you see our Maxima Rings return to zero, no matter how many times the scope is removed, or how many shots are taken downrange.

How are we able to accomplish this type of performance? Several factors are at play when creating a quick detach mount that can return to zero.  One of those main components that directly affect the mounts ability to return to zero is the recoil lug, or in our case the recoil key.  Some designs of rings use a screw going through one side of the ring, with a fastener on the other side to clamp the rings to the base, but also serving as the recoil lug.  This is adequate for building a low cost ring, and it will mount a scope to a base, but if you consider the overall amount of surface contact you have with the base slot, it is far from ideal. You essentially have the points of screw threads absorbing the recoil energy. The stainless steel, flat faced recoil key we utilize is a separate piece. It serves no other function than absorbing recoil, and giving a solid and consistent surface to contact the front face of the base slot.


A solid recoil key combined with a precision machined ring body, and clamp provide the essential ingredients for reliable return to zero once a scope is removed and reinstalled. Correct installation is the other main factor for a mount to reliably return to zero.  Our installation procedure is as follows:

“Remove the 4 screws from both rings. Place the scope in the ring halves and re-insert recoil key. Start all 4 screws on both rings and tighten bottom screws to 25 in/lb* max. Place rings onto the bases with the recoil keys in the slots. Push each ring towards the muzzle to seat the recoil key and tighten QD lever, thumb & forefinger tight. (There is no need to over tighten QD lever) Adjust eye relief and level the reticle. Once both are correct, tighten the top screws on both rings to 25 in/lb* max.
*After tightening, pull QD levers out to index them to the desired position.”

One of the most important steps is to push both rings forward toward the muzzle as you tighten the lever.  When a rifle recoils, the energy is moving back and slightly up into your shoulder.  The scope wants to stay in place, so imagine a scope staying where it is and a rifle moving back, this places a load on the front face of the recoil key where it mates to the face of the base slot.  Pushing both rings forward ensures that both recoil keys are doing their job, and stopping any kind of movement.  When you remove the scope from the base and go to reinstall it, by pushing forward while tightening the levers, you are making sure the mounting system goes right back to the exact same spot.


Maybe you are a shooter who prefers the ability to remove a scope to access your iron sights, or one who likes to have several scopes zeroed to one rifle for different situations.  Perhaps you are like me and cannot fit your rifles in your gun safe without removing the scopes.  You can count on Warne Maxima QD Rings to return to zero every time, we guarantee it.
