Click on the Ruger ring selection chart link located on our homepage. You need to know three things in order to select the appropriate scope ring set: the Ruger firearm model; the scope tube diameter; and; the scope objective lens diameter. For all Ruger ring applications refer to the Ruger ring chart. Alaska Arms LLC Quick detachable rings are manufactured in the same heights that are offered by Ruger.

Look on the face of your Ruger rings for the ring #. This will be a single digit and will be a 3,4,5 or 6 for 1” rings or 4,5 or 6 for 30MM rings. Be sure to check the number on each ring as the Group 2 Ruger firearms use different height rings for the front and rear ring.

I see I can order your Ruger rings with the levers on the left or right side of the rings. What do I need to know to make this decision?

Typically, a right-handed rifle shooter wants the rings on the left hand side and a left-handed rifle shooter wants the rings on the right hand side. This places the levers away from the loading and ejection port. For single shots it is up to the shooter. Handgun hunters prefer the levers away from their body when the gun is holstered.

I ordered the wrong rings. What do I do now?

The ring set may be returned for exchange. You will need to pay shipping both ways and return all original material supplied with the ring set. Please note we only accept rings for return that have not been installed on a firearm. Returns are not accepted for exchange unless you supply the make and model of your firearm along with the diameter of your scope (1 inch or 30MM) and diameter of the objective lens. This will ensure that the mistake will not be repeated.

Do I need to use the friction paper that came with my scope rings?
