The monopod Can be bent conveniently accor ding to the nature of the t errain . The buffer is an a ngular shaft i nser ted from fight to left into the buffer hole located in front of the /lBgazine housing of the stock . It is locked on t he left side by means of a nut. It sustains the forward projection of the recavar and together with the recoil plate transmits the reooil IiJ. ring fi re t o toostod<. The butt sling asaelllbJ.;,t consists 01" the seet and lIl9iv-e1. 'l'he seat 19 attached to the butt and the swivel to the seat. '/he butt swivel and 101'l'er band S'Nivel are used to attach the slin&, l'he .!Jhape and position of the butt sling assembl,y for r1flh II'ld sha-t rifle differ. In the case of the rifle t he t:ut.t sling asselllbl,y is attached to the ixlttom of the hltt by means of lona 8'ld st'Qrt "crews. In the case of short rif-es it is attached to the left s ide of the butt by two '/lood screws. Since the "eat of the butt .ding assembly for the 5hort ri fl e is elevated to limit the forward tripping of the 9"ivel, the s ling can be easil,y adjusted for whi le weariOl a gas tllMk. The butt plate is attached to th e IJ'Id of the s tock by /Teans of long and .!Jna-t wood screws . It protects the butt 3ld strengthens the joint of the two materials whim for ms the butt. The ahape 0[ hand guaro for rifle and sn:. r t ri fle differs. The hand guard for rifle consists of tl"ll boc\y and lll!ltal frame. It cOYers the barrel f rom the t.op , prevQ'lts its an'" pro tects the hand f rom 14 )7 grasping t h e gun wh«l the barr el is heated. It, forwar d ooge iii clanq:led by the lower band and tte groove on it" bottom surface fits Oller the hand guard cat ch. Its rear end, the iM8r surface of which 1s attached to a metal f'l'ame, is inserted into the f r ont end of the TeaT sight base. The metal frame covers tm barrel and together with the hand &lard catch, prevents th e hand guard from 1Il0ving. The hand euard for the short rifle consista of the tDd.Y and JlEtal frame. It covers the barrel from the top and prevents it fro m moving and pr otects the hand in grasping the ritle when tile barrel 13 heated. It s rear end, the inner surface of w hieh is attached to a metal [r&IO, i s inserted 1.nto the fro nt end of the rear sight base. The nl)t.al frame covers the barrel from the top. Its front 8'1 d is c overed by the upper band '" h1Ch , together 'fd til the 10lfer band, prevents the hand g uard from lIlovi ng. The lower band 1s located about three and one-halJ inches in front d: the rear sight base and holds the hand guard and the stock together by IIEans of a screw. The cl eanin/( rod is used for claaning and stacking rifles. A male screw is provided Ilt the bottom end and a hole at the top end. When the occasion arises , cleaning rod jag, s wab, and awdliarl cleaning rod can be attached to the male screw, A piece of wood cr cloth mn be 'inserted 1n the top hole to facilitate cleaning. II Function of the breech roechani!llJl J8 The relationship bet'lfeen the receiver and bolt during tire iSI (a) When the bolt is opened and fhe rounds contained 1n the cartridge clip are loaded into the ma.gaune l ocated at the front of the l1lc6iver, the rrunds depresa the follower and stack up three to the r1gj:J.t and tlfO to tJ1e left • The rc:unds are raised upward by ceans of the magazine spring. (u) Wh8'l the bolt 1s pUl!lhed fol'tjard. the clip is released by the press ure I exerted at the uottOlll by the bolt . The uppemost round, pUl!lhed from the rear, 15 , I slides up the cartridge ranp loeatetl in f r ont of the port at the bottom of the receiver and ert.ers the charrber. At this instance the extractor engages the rear gtloove of the cartridge in preparation for extraction. (e) When the bolt is completely closed and the trigger pulled, the sear is lowered, this disengaging it. fmlll tJle cocking lever . The cO'lllressed firing pin .spring drives the firing pin forward until 1l'le firing pin stri kes the primer of U\ e c &rtrilJge. At this tiwe the b:llt handle will net open since the safety lock has engaged.t.h&:s ai'et;rlock groove of 1l'le bolt . Furthermcrs, when the breech is not elosed prope rly, the trisger cannot be pulled since the safety lock will not be in Jl.ttfe liith the groove. ThIllI', a safety meansure is provided. -bolt handle i e raised and t.he bolt 1:9 broudlt to the rear, the ej ector, by means of ejector splings, !!Iters the ejector groove of the bolt housing and ejects the cartridge, ·.tIidi has been extracted by the extractor. When the Lvlt. is pu ... led back fu l l.7 , it. is prevented rn.:.m slipping out of the l'e cfl'\. vl!r nCe thl! bolt. cRt.ch I!nVle"'" t.h .. holt. lug. (e) When t ne bolt is again brought forward, the rext roU'1d is loaded, dis_ charged, 8:td eject.ed in t.he Sa'lle manner lUI the pr evious round. (r) When all of the rwnds have been 8X?8nded the follo .....er catches the bolt face and prevents i ts advll1ce. This indicat.es to the firer that the I!I8.gazine is empt.y. 39 Safety CIl1 be Il'aintained by the saTety lock ann s afet:.y knob. The function of the sai'et.y lock has been explained in (c) of 38. The safety knob in operation prevent.s the bolt. handle frolll and locks the tri gger. In shert, the safety knob is operated in the followill6 IMrmer . When the safety knoh is pressed forward , turned 45 degrees to t.ne ri l!J1t., t.he safety knob catch enters the wrved gr oove in the resr of the receiver and locks the safety krob. \'lhen this is done, the small projection at Ute rear of the bolt. handle engages t.he races" 0:1 t.he outer fringe of the safety knob Md prevents the bolt handle 16 and wlt from opening. At the sane time the firing pin turns with the safety knob, the sear cateh moves from the firil'l6 pin eatch, enters the left reeess MId disengages the firing pin from the sear, thereb:1 locking the tr:!. l!ser. When the 811.fety knob is l ocked, the position of the semicircular cut on the rear upper 18ft of the safety knob is chanSed t.o an upward posi lion. CMpter 2 Accessories 1. 2. J. 4. 5. 6. 7. B. 9.
