Remington 700 Bolt Lift Kit SV (Small Version)

Works extremely well for the price. Easy to remove, but a little temperamental to install. Overall, I recommend it. The "small" seems like an excellent size. I think the regular/large model would be too large to clear lower scopes or larger scope rings.

Advantages: Light. Removable.

Disadvantages: Unless you epoxy it in, there will always be a small amount of play. It bothered me at first, but after some use I discovered that play helps with leverage.
