Remington Model 700 Trigger Assembly

 

 The Remington Model 700 Trigger

 

This is the Model 700 trigger assembly. What seems to happen with the trigger is the Detent Safety Ball puts pressure on the trigger just enough to cause the gun to fire when you move the safety from "Safe" to "Fire". this could be aided by the dirt gummed up on the trigger assembly parts. Below is a picture of the Detetent Safety Spring before disassembly.
 

 

Below is a picture of the Detent Safety Ball and the dirt and grime that can build up on the parts of the trigger assembly. Notice the same sticky gum that builds up on the outside of the assembly can build up on the inside of the holes, trigger and ball. In these pictures a lot of the sticky gum has been wiped off of the housing before the picture were taken.

 

Okay in the next picture the trigger, assembly, and parts  has been cleaned and the trigger assembly was mounted back on the gun and adjusted. I then removed the trigger assembly and left the adjustment screws in place and ONLY removed the safety so as to expose the Detent Safety holes and other parts. The top hole shows the Sear Safety Cam and how it sits on top of the trigger when the gun has been cocked and ready to fire. The next two holes below that shows where the Detent Safety Ball travels from hole to hole as the Safety is moved from Safe to Fire.

When the safety is moved from Safe to Fire the Detent Safety Ball moves from the top hole to the bottom hole. When the ball falls in the bottom hole it strikes the edge of the trigger. If the trigger weight is set too light, then the force that the Detent Safety Ball Spring puts on the ball causes the ball to strike the edge of the trigger and move the trigger slightly forward. If the Sear Engagement is set too close to the edge of the Sear Safety Cam then this can help aid in accidental firing when the trigger is moved to the fire position. 

Notice in the picture how on the back side of the trigger (inside the bottom detent ball hole) there is a shiny strip on the edge of the trigger. This indicates that the Detent Safety ball is indeed hitting the trigger and putting pressure on the trigger that could cause the gun to fire when the safety is moved from Safe to Fire. The trigger only has to move foward just a little to let the Sear Safety Cam fall down. Once the Sear Safety Cam falls down the gun fires.

The Sear Safety Cam also needs to be free of gum and dirt  to help the trigger move back to the Sear Adjustment Screw. If the Sear Safety Cam is dirty it could aid in a misfire by not letting the trigger come all of the way back. If someone was to drop the gun and jar it, that  may cause it to slide off and fire.  Enough tension on the Trigger Weight Spring can help avoid that type of misfire.

 

 

Now in the picture below again I'll address the position of the Sear Safety Cam and the Trigger when the trigger has been fired. The top hole shows how the Sear Safety Cam has dropped down beside the Trigger after it has fired and is still in the "fired" position. Notice now the gap in the hole for the Detent Safety Ball and the back edge of the trigger. It has increased and you can clearly see how the Detent Safety ball would still have an effect on the trigger in every position that the trigger moves in when the screws have been adjusted so that the trigger assembly is fully adjusted.

There is not doubt that the ball affects the trigger by the weight of the detent ball spring. If the parts are oiled and kept free of dirt then the ball may not be as likely to move the trigger when the safety is moved from Safe to Fire. I do believe however that Remington could have made a simple improvement to the trigger assembly just by grinding the back of the trigger only where the detent safety ball hits the trigger. This would eliminate any possible movement to the trigger caused by when the saftety has been moved from Safe to Fire.
