presses down on the trigger bar and thus aligns the trigger bar and 
scar. Prcssurc on the trigger will force the trigger bar to move 
forward and disengage the scar from the hammer. The hammer 
swings forward to fire the rifle (A, f’ig 9 ), and as it does, a cam 
on the bottom of the hammer dcprcsscs the disconnector, which 
in turn dcprcsses the trigger bar below the scar. The scar spring 
forces the sear back against the harnnrer. 
C. 
When the hammer is rocked back by the bolt, it strikes 
the disconnector and depresses it. 
The disconnector insures that 
the contact bctwecn the trigger bar and the sear is broken by 
depressing the trigger bar 
(B, fig 9 ). When the bolt

counterrecoils, 
the hammer moves forward slightly, off the 
disconnector, which rises and allows the trigger bar to rise against 
the bottom of the sear (the disconnector having risen to its highest 
point). When the trigger is released, the trigger bar moves rearward 
until it is clear of the sear, then it springs up (if the bolt is locked) 
against the disconnector, and the rifle is ready for another shot (C, 
fig 9 1. 
11  
						

							f. The disconnector (B, fig 9 ) prevents the rifle from 
firing if the bolt is not fully lockcc!. It does this in two ways: by 
its control of the position of the trigger bar; and by a notch in the 
disconnector, which intercepts the scar notch of the hammer if the 
disconnector is not fully dcprcsscd, such as when the bolt is not 
fully lock& 
6. The safety, when rotated up to the safe position, places 
a block behind the trigger and prevents the trigger from being 
pressed. 
h. The bolt catch is normally held depressed by a light 
spring. When the last round is fed from the magazine, a nib on the 
magazine platform contacts the catch and forces it upward. As the 
recoiling bolt passes the catch, the catch protrudes into the bolt 
path and holds the bolt open.
