Aftermarket AICS Buttpad

[celtics10]

Does anyone make a stickier and softer AICS buttpad? I was shooting prone slightly uphill in the rain the other day, and even with a good firm bipod load the pad would slip down a bit in my shoulder under recoil. I was hoping a stickier pad with more give would give a better purchase. Best case scenario would be a pad like the ones that come on the KMW stocks, I shot someone's 6.5 SAUM at the range the other day in a KMW and it was the gentlest push of recoil I've ever felt. Thanks.
