The HAND GUARD RING is shown in side and front elevations in Fig. 98. It includes the barrel loop A and the guard seat B. The rear tenon of the rear hand guard is held in this guard, seat. The front tenon of the front hand guard enters an undercut in the upper band. The adjacent ends of the two guards abut, and the joint is lapped by the lower band. . The BUTT PLATE is shown in, top view in Fig. 99 and side view in Fig. 100. The parts are the toe A; tang B; cap hole C; cap ears D, through which are the pin holes E; the spring lug F; hole for large butt plate screw G; and hole for butt-plate spring screw H. Some manufacturers form the ears integrally with the butt plate; others rivet them in place. There is a hole in the tang for the small butt plate screw. The BUTT PLATE CAP is, shown in inside view in Fig.101 and in side view in Fig. 102. It has the pin hole A, detent faces B; and thumb notch C; and is pivoted between the ears on the butt plate by the BUTT PLATE PIN, Fig. 103, which is riveted in place. The cap is impositively latched in open and closed positions, by the BUTT PLATE SPRING, Fig. 104, held by the BUTT PLATE SPRING SCREW, Fig. 105, and bearing against the detent faces B. The BUTT-PLATE SCREWS, LARGE and SMALL, are shown in Figs. 106 and 107, respectively. The small screw goes through. the hole in the tang. The STOCK BOLT AND NUT are shown in Fig. 108. The bolt extends transversely through the stock, just to the rear of the recoil lug on the receiver (see P, Fig. 89). The STOCK PIN, Fig. 109, is a threaded pin, of brass, screwed through a transverse hole in the stock, between the magazine well and the trigger slot (see Q, Fig. 89). Its ends are cut off flush with the sides of the stock. The UPPER BAND shown in end and side elevation, respectively, in Figs. 110 and 111 has the bayonet lug A; ears B, in which are the holes C for the STACKING-SWIVEL SCREW, Fig. 112; an undercut D for the front tenon of. the hand guard; and the upper band screw hole E to receive the UPPER BAND SCREW shown in Fig. 113. All swivel screws (Fig: 112) have hollow ends which are expanded by the use of a special expanding tool to prevent their becoming loosened. The STACKING SWIVEL is shown in edge and top views, respectively, in Fig. 114 and Fig.115. It is mounted with its lug A between the ears in the upper band, and swivels on the stacking swivel screw above mentioned. The LOWER BAND, Figs. 116 and 117, has the ears A and. holes B. The LOWER BAND SWIVEL, Fig. 118, has an offset lug C which lies between the ears A, and swivels on a screw identical with the stacking swivel screw, Fig. 112. The lower band is retained by the LOWER BAND PIN, Fig. 119, which passes through the stock (see R, Fig. 89). The BUTT-SWIVEL PLATE, Figs. 120 and 121, has the screw holes A; ears B and swivel screw holes C. A swivel and swivel screw, identical with those used in the lower band (Figs. 112 and 118), are used with the butt-swivel plate. The butt-swivel plate is attached to the butt by two BUTT-SWIVEL PLATE SCREWS, Fig. 122.

|
The BAYONET is shown in side view in Fig. 123, fragmentary rear edge view in Fig. 124 and top view in Fig. 125. The blade A and tang B are forged in one piece; the guard C is forced on to the blade, and brazed in place, and the pommel D is brazed in place so that these parts practically form a single piece. The guard C is formed with the barrel ring E, to surround and thus engage the end of the rifle barrel. The pommel D has a T-shaped stud slot F to receive the bayonet stud, on the upper band of the rifle. The clearing hole G leads to the end of the stud slot and facilitates the removal of dirt and other obstructions. The BAYONET CATCH is located at H, Fig. 123, and is illustrated in detail in Figs. 126 and 127, which are end and side elevations, respectively. It includes the latch A; body B; shoulder C; and threads D. The CATCH THUMB PIECE, shown in outer end view in Fig. 128, side view in Fig. 129, and inner end view in Fig. 130, screws on to the threads D of the catch, and seats against the shoulder C. It has the turning slots E, and spring seat F to receive the end of the BAYONET CATCH SPRING, Fig. 131. This spring surrounds and partially guides the body B of the catch, and serves to hold the catch in engaging position, with the thumb piece protruding from the pommel. The catch is released by pressing the thumb piece. Two counterpart GRIPS (right and left), Figs. 132 and 133, are mounted on the tang, between the pommel and guard, and are held by the BAYONET SCREWS AND NUTS shown in Fig. 134. The grips are counterbored, as shown, to receive the nuts and the heads of the screws. The marking of bayonets taken over while in course of manufacture for the British Government, includes a canceled British property mark, On the blade, at the guard, on the same side with this, are the letters "U. S." and the inspector's marks. On the reverse side is "1913" (the British designation of this model), numbers representing the month and year of manufacture, and the maker's name. Bayonets of later manufacture bear on one side of the blade at the guard the Ordnance escutcheon, the inspector's marks and the letters "U. S." On the reverse side is "1917" (the official U. S. designation of this model) and the maker's name. The bayonets are not serially numbered. The BAYONET SCABBARD, model of 1917, is shown inside elevation in Fig. 135 and edge view in Fig. 136. The body A is made of sole leather, flesh side out, stitched up the inner side, and painted olive drab. The ferrule B and mouthpiece C are of sheet steel, browned. The hanger D is of russet leather and carries the double hook E by which the scabbard is attached to either the pack or the belt. The bayonet is retained in the scabbard by spring fingers (not shown) mounted in the mouthpiece, and serving frictionally to engage the blade.
