I just purchased a new in box remington sps tactical aac-sd and it has the newest x mark pro trigger and contrary to literature it only adjust down to 4 lbs consistently. I have been making tiny 1/4 to 1/8 turn increments and it fluctuates from 4.5 lbs to 3.5 lbs. If i get it around 3.5 lbs it only last a couple pulls then goes up to 4 again. My local gunsmith does not want to work on it because he is not used to this trigger. I can buy a spring kit from earnie the gunsmith for around 7 dollars. Can I just adjust out the front screw a turn and get it into adjustment. Not looking for bench rest trigger but a 3 lb trigger to match my other guns would be nice. I have owned remington 700s for 15 years now and work and customize them myself usually trigger included. I have not worked on this trigger either. Does it adjust the same way? Surely I can get a little more adjustment out of it.
