One world war two british enfield number four mark two or one enfield .303 caliber rifle training sight,periscope type,one ond is inserted in the camber so the instructor can determine if shooter has figured out the basics of rifle marksmanship and breath control ( BRM ).,nifty little accessory for the collector who has everything.very similiar to the US type,but I guess the british wanted to look over the shooters shoulder instead of off to the side.,overall good condition,see my other listings for more british enfield rifle No. 4 Mk.1 or 2,and WW1 No.1 Mk.III parts and accessories
