I enjoy my Pro Varmint a lot. It's great for bench or prone shooting. It wouldn't be so great for carrying for small game hunting and shoulder firing.
Mine seems fairly rigid. I bet I could balance it between a couple chairs and stand on it without it flexing much.
The forearm area is much fatter than a sporter style stock forearm. So if you have a standard rimfire contour barrel, the proportions might not look good.
I would buy another in a heartbeat, and probably will for a future project. Next time I don't think I will pay the extra for the adjustable comb option though. It doesn't adjust easy enough for me to want to mess with it whenever I need to clean the rifle, and if you don't move it it just gets in the way. Hope that helps!
