So, you’ve decided to tune the trigger of your gun. What do you do to make sure it’s done in the best possible way?
Follow the next instructions and you will succeed.
To remove the adjusting screws and springs, first, take out the “Trigger Adjusting Screw” – be cautious of the small ball bearing that might come flying out with the spring.
Next, most of the time Remington fills up the screw holes with wax or something similar. Gently dig around until you expose both screw heads and trigger adjusting screw stake.
You should then use lighter fluid to completely clean out the oil, grease, and other waste. If you have some aerosol brake cleaner, go ahead and blast it with that first. Then apply some lighter fluid. Give it a good soaking while you’re at it. Do not oil the trigger; the lighter fluid will take care of that.
You may put a little oil on the screws and springs after you’ve cleaned it. Let’s start with the trigger adjusting screw, spring, and bearing. First, insert the trigger adjusting screw, spring, and bearing into the gun. Set it so that the bearing just barely fits in the chamber. Now insert an empty case into the chamber and close the bolt. It should remain cocked after doing this process twice.
Now put in the trigger engagement screw and slowly tighten until the sear releases and the firing pin drops. Now try backing out this screw 1/3 turn. Re-cock the bolt and see if the sear stays engaged. You can also check whether or not it is staying engaged by looking through a hole at the top center of the trigger.
If the firing pin falls when you close the bolt, back out one-quarter turn and try again.
Now let’s look at the weight of pull. If it’s still way too heavy, you might consider removing a coil from the spring.
Make sure the trigger does not protrude too far and that it returns readily! Insert the trigger stop screw now and set it so that there is minimal overtravel after the sear releases. (Insert till it’s tight, then back out 1/4 turn)
Now go back and fine-tune (readjust) the trigger engagement screw; you may even be able to turn it in a little.
Always test your gun before use by doing ‘Thump and Bump’ tests. Make sure to do these with the safety on and off, cocking the bolt between each test. This will ensure that it does not slam fire. Be safe – TEST – and TEST again!
