Cheek Eez is a buttstock cheep pad made of Sorbothane which delivers exceptional shock absorbing qualities. Ambgun first used the Cheek Eez to raise the buttstock comb on a Marlin 45-70 Guide Gun to achieve optimal cheek weld with proper eye to scope alignment….see our video, Marlin 45-70 Guide Gun for The Ambidextral Hunter. https://youtu.be/in1iduin-hg AmbGun is Currently testing the Henry 22Lr and 17 HMR Express and once again AmbGun is using the Cheek Eez to achieve proper eye alignment with a rifle scope. https://www.ambgun.com/ambidextral-rifle/17hmr On the Henry 22Lr, we used a ¼” Cheek Eez whereas on the 17 Express, with its taller buttstock comb, we used a 1/16” Cheek Eez. And our Mossberg MVP Predator got the ⅛” Cheek Eez. Carefully clean the buttstock using the included alcohol wipes.
