Ruger 90746 Comb Riser Kit Polymer Black Generation II

The Ruger 90746 Comb Riser Kit is an official Ruger factory accessory designed specifically for the Ruger American Rifle Generation II. Built from durable black polymer, this kit lets you adjust comb height for a more consistent, comfortable cheek weld and improved sight alignment through your optic or iron sights.

The kit includes two interchangeable combs. One comb raises the comb by 5/8", while the other raises it by 3/4", letting you tune the stock geometry to match your scope height, eye relief, or preferred shooting position. Combs are easy to swap by loosening the recoil pad, with no permanent modification required to the rifle.

Whether you are dialing in a new scope, switching between magnified optics and iron sights, or simply chasing a more neutral head position on the stock, the Ruger Comb Riser Kit is a straightforward, factory-original upgrade for the Gen II American Rifle platform.
