43.  ORGANIZATION SPARE PARTS. --  a.  The parts of any carbiine will in time become unserviceable through breakage or wear resulting from continuous useage, and for this reason spare parts are supplied.  These are extra parts provided withthe carbine for replacement of the parts most likely to fail, for use in making minor repairs and in general care of the carbine.  They should be kept clean and lightly oiled to prevent rust.  Sets of spare parts should be kept complete at all times.  Whenever a spare part is taken from the set to replace a defective part in the carbine, the defective part removed should be repaired, or a new one procured, and replaced in the spare parts set as soon as possible.  Parts that are carried complete should,t all times, be correctly assembled and ready for immediate assembly to the carbine.  The allowance of organizational spare parts is prescribed for the carbine in SNL B-28.
     b.  With the exception or replacements withthe spare parts mentioned in  a  above, repairs or alterations to the carbine by using organizations are prohibited.

     b.  Brush and thong. --  The brush and thong are used for cleaning the bore of the carbine.
     c.  Case, cleaning rod, cal. .30, M1. --  This case is a fabric containerr seewed  to form  five pockets to hold the four sections of the cal. .30 jointed cleaning rod M1 and the cal. .30 cleaning brush M2.  A web-shaped billet and buckle are sewed on the front of the case to secure the flap, and a web hanger with brass hook is sewed on the back of the case to secure it to the ammuntion belt.  (Will also be used for rod M8.)
     d.  Rod, cleaning, jointed, cal. .30, M8, w/brush, cleaning, cal. .30, M2. --  (1)  Rod, cleaning, jointed, cal. .30, M8. --  The cleaning rod consists of two sections threaded together.  Attached to end of one section is a swivel handle to facilitate use of rod.  The handle allows the rod to rotate with the twist of the barrel, and acts as a stop to prevent the opposite end of the rod from striking the fwace of the bolt when in use.  The end opposite the handle is slotted for assembly of the cleaning patch and has a threaded hole to permit assembly  of the cleaning brush M2.
     (2)  Brush, cleaning, cal. .30, M2. --  The cleaning brush M2 is a brass wire brush composed of a twisted wire core which retains the brass wire bristles constituting the brush.  The core is fastened to a threaded shank by which the brush is attached to the slotted end of the rod.
     e.  Sling, carbine (Figure 21). --  The carbine sling is an olive drrab, cotton web strap, adjustable to the soldier using it.  In one end are the two button holes about  3 ¾  inches apart, through which a bronze button passes to form a loop.  To the other end is attached a lock buckle through which the sling passes.  The lock of this buckle can be released to allow the sling strap to slide through the buckle and then locked upon thje strap to hold the adjustment thus attained.  The button end of this sling passes around the oiler through the opening in the left side of the stock after the oiler has been positioned in an aperature  on the right side of the stock near the butt.  The button holes are then mated and the button passed through them to hold the oiler in the loop so formed.  The outer end of the sling strap passes through the sling swivel attached to the left side of the front band.  The oiler acts as an anchor pin for the rear end of the sling as well as a means of lubricating the carbine.
     f.  Oiler, carbine (Figure 21). --  The oiler consists of a tube to hold lubricating oil, a steel ring or cap seat, and a threaded cap in which is positioned a rod, or a dropper.  The oiler also acts as an anchor pin for the sling as described in  e  above.
