The Remington Model 40X small-bore target rifle was introduced in 1955. Chambered for the cal. .22 long rifle cartridge, the Model 40X is of single-shot type with speed-lock firing mechanism. The bolt has 2 large locking lugs. The upper lug engages the forward edge of the receiver bridge, whereas the lower lug is housed in a mortise cut into the bottom of the receiver.
The trigger mechanism is adjustable for weight of pull, travel of trigger, and overtravel of trigger. Adjustment for weight of pull is made by loosening or tightening an external screw that is located within the trigger guard loop.
The barreled action must be removed from the stock assembly to make the other trigger adjustments. Amount of trigger travel is varied by adjustment of the trigger stop screw in rear of the trigger assembly. To make this adjustment, screw in trigger stop screw until firing pin will fall without trigger being pulled. Then back off trigger stop screw approximately 1/8 turn, or until firing pin will not fall unless trigger is pulled...
