After 77 years of incurring injuries, operations, and shedding blood and sweat as a pipefitter and doing heavy machinery repair I now like as little pain and discomfort as possible to come into my life so I got this slip on recoil pad from Limbsaver for my .50 cal. Hawken and am pretty happy with it. No problem continuing shooting past that first dozen and I can go back to shooting off my shoulder rather than off my bicep, which always seemed awkward to me. I had to make a little insert for it out of some Styrofoam packing material to fill in the gap due to the strong curve of the Hawken buttplate. I wish the sleeve was a little longer and thicker but it is easy to slip on at the range and almost eliminates the felt recoil.
