Oh this is too cool! I can finally take all these accessories for my M-4 and other rifles and throw them on my 10/22 and practice on my own time. It's a real bummer the bottom rail doesn't effectively fit a Harris bipod and a front grip, but it can be made to work - albeit awkwardly. The side rails are rather long, so I guess you can fit the world's longest flashlight or infrared laser on there :-p The covers are a nice touch, but the grip is too fat to grab as comfortably as the factory stock setup. But if you're buying this, you probably aren't concerned about wrapping your hands around it. Also, buyers beware on the Butler Creek folding stock: this is not such an easy fit. I took out the front barrel spacer to make it fit, but this made the rail forward of the factory scope mount tilt slightly forward. Just a word to the wise. Finally, I am not a paid representative. This has worked out well for me, and I want to let you other CTD buyers know of my personal success with this product.
