777R (Long Action, .700 Diameter Bolt)

 This action is a long action and will accept BDL or it will mag feed.

This action has an integral rail and lug. Like our short action, the 777R has been machined with the extremely tight tolerances that we have been known and respected for. Indexing and headspace will be held to the same standards we have been known for, allowing for prefits.
