This little part makes a huge improvement on the Avenger rifle trigger. The force needed to cycle the trigger does go up a tiny bit but it changes to the Avenger rifle trigger to a very crisp trigger with no creep. This makes the trigger very predictable which helps improve accuracy even more.
It is easy to install and adjust to get a trigger that is just right. After installation and with proper adjustment the Avenger rifle trigger is on par with the high end airguns. I have it on my Avenger .25 rifle. It had too much creep in the trigger and I had a hard time knowing when it would break when making longer range precision shots. Now it is a nice 2 stage trigger with no trigger creep and is very crisp and predictable. It has made a huge difference in my ability to make precision shots.
