Limbsaver Recoil Pad for Knoxx Stock

I like the Knoxx SpecOps stock because it reduces recoil as advertised. But I have always wondered if it is possible to reduce recoil even more. This weekend I have tested Knoxx SpecOps stock with Limbsaver Recoil Pad. I haven’t noticed much difference. So, I think it is not necessary to change the standard Knoxx recoil pad.
