(b) The foresight; that the barleycorn is not deformed.
(xiv) The bolt; that the striker is not too free on the cocking-piece, and that it is not screwed too far into the latter; also that the striker keeper nut-screw (or the striker keeper-screw if fitted) is not broken, and that the nut is in its proper position.
(xv) The bolt-head; that the charger guide is not too loose on the bolt-head; that it works smoothly; and that the top screw is intact.
(xvi) The safety-catch and locking-bolt; that the safety-catch engages in the camway of the bolt and locks it; that it does not move too easily; and that the cocking-piece is withdrawn slightly to the rear when the locking-bolt is applied, whether it is at “full cock” or the “fired” position.
(xvii) The butt; that it is not loose. If the stock-bolt requires screwing up to tighten the butt, the fore-end must first be removed. On reassembling, great care will be taken that the square end of the stock-bolt which protrudes through the socket of the body is in the correct vertical position, so that it may enter the keeper-plate properly when the fore-end is replaced. On replacing the fore-end, see that the fore-end stud and spring, where fitted, are in proper position; the front guard and inner band-screws must be tightened carefully.
5. Examination of Short, M.L.E., Mark III, and Converted Mark IV Rifles.—The same as (i), (iii), (vi), (viii), (ix), (x), (xiv), (xvi), and (xvii), with the following additions:
(xviii) (a) The backsight leaf, for firmness of the joint; that it is not bent; that the windgauge fits firmly; that the slide moves smoothly, that the thumb-piece and fine adjustment worm work freely and engage in the rack on the side of the leaf; and that the U is not deformed.
(b) The foresight; that the blade is not deformed.
6. Drill Purpose Rifles.—These instructions apply also to Drill Purpose rifles. As these are used for the instruction of recruits in aiming, particular attention should be paid to the state of the sights.
