I don't know what an R5 is, but I can tell you this... I love the old HS Precision stocks, back when they didn't have a palmswell. I have several and prefer them over the newer ones with a palmswell. They are the same exact stocks, just one has a massive palmswell, and it doesn't feel right in my hand, because years ago I had surgery on my right hand, and still have metal plates fusing bones together, so my hand doesn't flex and bend normal, so finding a comfortable grip with the palmswell is very difficult for me. It's a personal preference. You might like them.[/QUOTE
