I like all the post on the Avenger. I own an Avenger in .177. They shoot pretty good. I love to hear about other mods to the Avenger.
On my Avenger I added an extra barrel band and tuned it. Someone asked about a better trigger. I modified the trigger block on mine to add a sear adjustment screw that also functions as a trigger stop screw. It still has the 2 stage trigger and the safety still works. With lighter springs installed it starts at 6 oz no creep and no over travel. This can be adjust a little heavier. This a little light for me in field target so I reinstalled the factory trigger springs and it now starts around 10 oz that I adjusted up to 11 oz which work fairly well for me.
