The lug I! has an aperture 23 adapted to align with the slots I6 of the flanges and a bolt 24 rangements, and combinations herein described is extended through the slots and the aperture 5 and claimed. 23. The bolt 24 has a head 25 of flattened forma- It is an object of the invention to provide a tion so as to seat within one of the flanges I6 sight which may be readily used as a peep sight, and thus prevent its turning when tightening the adjustable upon its base support so as to be nut 26 which is engaged. upon the threaded porlo adaptable to various ranges, as well as being sustion of the bolt. The bolt 24 has a flat 2'! for a ceptible to use as a receiver sight. p p as W new be eXpleined- It is a further object of the invention to provide The lug I! has a bore 28 extending longitudia peep or similar sight which may be quickly nally thereof and houses a helical spring 29 and folded to an inoperative position, a detent 30.
