Setting the trigger on the QB78 and 79

NB this is NOT a tuning guide, but just some instructions on how to set the trigger.

The QB 78's trigger is adjustable for sear engagement, pull weight, and over travel.

Start by removing the action from the stock: undo the knurled nut in the forearm and put the safety to the safe position. Using a non-marring punch (such as a wooden dowel), push the safety out from the trigger unit frame. The QB79 have 2 screws in the front of the stock that need to be removed as well.

Looking at the trigger unit, you will notice there are 3 screws used for adjustments:
1. the large screw at the bottom - is for pull weight. Unscrew it 2 turns and test the feel of the trigger (it should be about 1
lb.. however, you can adjust it to your liking).
2. the middle screw - is for overtravel. Screw all the way in to eliminate all the creep.
3. the top screw is for sear engagement and compensation of future wear. DO NOT ADJUST AT THIS TIME. I dont know how long wear will take.

Put everything back together. You'll see an immediate improvement.
