I have a Harris on my 7mm Rem. Mag. rifle because it has a very heavy recoil and I think it can take the abuse. However, for my .22's and even my AR-15 that have little or no recoil, I use the Harris look alikes that are sold under names like Caldwell, Shooter's Ridge and Winchester for about half the price of the Harris. While I'm sure the materials are not the same as the Harris, they are almost indistinguishable in form & fashion otherwise. They work very well and I havent had a single problem with any of them over years of use.
