Fits henry bigboy x - ADE Advanced Optics Adapter/Mounting Plate for Red Dot Sight

Purchased the Marlin 336, 444, 1895 mount to use on a Henry BigBox X model. Fit perfect with no Gun Smithing required. The mount does hang off the rear some but does not interfere with the hammer operation, I have had no issues with cocking or de-cocking the hammer. I also used one of the Burris FF3 picatinny protectors and removed the mount and put it on the marlin mount. Have put quite a few rounds thru with no issues. I did red lock tight the screws that join the base to the protector and blue lock tight all the other ones. Over all very happy, I know its not the normal sight for a Henry Rifle but all of my hunting with this gun is less than 80 yards so the FF3 works perfect for me and is much faster then a scope.
