This is the fourth Badger Ordnance Pic-rail I have bought/used for my rifle scope mount bases. They are the BEST on the market for ant Pic-rail mount. This one, with 20 MOA cant will be used on a .300 Win Mag hunting rifle. It has a recoil lug that secures it to the rifle action so recoil force is not applies to the mounting screws. It is simply the best. Get one.
