mk11

I had the opportunity to do some shooting with a U.S. Navy Mk.11 Mod 0 rifle yesterday. These are usually employed by "marine mammals". I was wearing hearing protection out of habit. In this case I really didn't need it.

I have an older Ruger MK11 with a bull barrel and the original plastic stock grips. Where is a good place to look at grips and what is a good grip to think about trying with my Ruger MK11 for target shooting? Thanks for any help
