This little part makes a huge improvement on the Avenger Bullpup trigger.

It is easy to install and adjust to get a trigger that is just right. After installation and proper adjustment the Avenger bullpup trigger is on par with the high end airguns. I have it on my little Avenger bullpup .177 that I use for long range shooting of pest birds with the JSB Beast 16 grain pellet. I routinely make shots to 100 yds on starlings and house sparrows. I could not make these shots before the trigger sear tuner because there was so much creep in the trigger. It had too much travel and I had a hard time knowing when it would break. There was no feel to it. Now it is just a nice 2 stage trigger. The second stage now has the slightest amount of travel and the trigger breaks. It has made a huge different in my ability to make precision shots.

Installation instructions

Remove the stock from the Avenger bullpup by removing the two screws on the bottom of the stock and 2 screws on the side of the stock. You will need a long 4mm Allen key and a regular or long 3mm and 2.5mm Allen key for this. Allen key to adjust the sear tuner is a 3/32 

The spot for the trigger sear tuner is already there and the holes are already in place.

 

Drop in the trigger sear tuner with the center adjusting screw towards the back of the airgun. Install the 2 stainless steal grabber screws and snug those down. 

Since the bullpup trigger now moves back and forth with the stock removed it is easiest to adjust the sear tuner by another method. 

Please be careful and it is best to remove remove the pressure from the air system of the air gun. All liability is on you at this point. 

Cock the air gun and leave in a cocked state. Slowly adjust the center Allen screw in until the trigger breaks. It will cycle a shot if the pressure is not released from the air gun. Allen key needed is a 3/32 

Then turn the adjuster screw out (counter clockwise) 1/2 to 1 turn. This will set the sear with a small amount of travel needed to break and you will have a very nice, crisp trigger break.
