I have a Hogue grip, and it feels good. But I think the finger grooves are a little deep on that grip, which is a good thing so you grip the rifle perfectly every time. But the look of the Hogue grip on the 15-22 looks a little small or skinny, especially compared to the MOE grip that I pulled off of the rifle.
I'm liking the look of the Ergo grip where the finger grooves are not so much protruding outwards, and there's a beavertail on the grip like MOE grip. I may try to get one of those and see how it feels compared to my Hogue grip.
