I recently adjusted the new X-Mark Pro trigger on my Remington 700 VTR, so I figured I'd let you guys know how it's done. Note: once you adjust the trigger, you will void the factory warranty on this part! 1) Make sure the gun is empty of ammo!! Take of the stock, very important, you can't adjust the trigger with the stock in the way lol. 2) Flip the barrel over, with the trigger facing up. The adjustment screw is on the front of the trigger assembly in the middle. There is only one adjustment screw, and it is a 1/16" allen key. 3) Clean off any epoxy or anything that might be holding the screw in place. 4) To lighten the trigger pull, turn the screw counter clockwise. To increase pull weight, turn the screw clockwise. It would help to count the turns that you made, so that if you want to return to the previous pull weight you can easily accomplish it. I managed to lighten my trigger pull to about 4 lbs. 2 oz. (counter-clockwise). Note: if the trigger pull is too light, the bolt will not cock, so increase trigger pull (clockwise) by about 1/4 turn at a time until the bolt cocks. 5) Now, check to make sure that your gun won't slam-fire. Make sure the gun is empty of ammo again, and snap the bolt closed as hard as possible. Also, work the safety on and off a few times. If the gun doesn't dry-fire, and everything is fine, great. 6) Now, back the trigger adjustment screw out 2 full turns (counter-clockwise) and clean the screw and the front of the trigger assembly off with acetone or another degreaser. Apply blue Loc-Tite or another removable thread-locker to the screw very sparingly. Then re-tighten the screw 2 turns, and wipe off any excess. 7) Check for slam-fires with the bolt again. Replace the stock, and drop the rifle on its butt a time or two from about 6 or 7 inches to make sure it doesn't slam-fire again. If not, you're good. Congratulations! Hope this helps someone.
