Based on Warne's innovative R.A.M.P. Mount platform, this Gen II Edition has all the features you need. The X-SKEL Mount offers a lightweight scope mounting solution for your MSR style firearm with the same durable, return to zero reputation that you've come to expect from Warne. This mount is CNC precision machined from 6061 aluminum with reduced the weight by over 30 percent. The X-SKEL provides an additional inch of forward cantilever, compared to the original SKEL Mount, as well as a 1 piece side clamp design for additional strength. The extra cantilever provides proper eye relief when using scopes with large eye boxes and will give extra space behind the mount for accessories.
