Only 5 refurbs left now. Accuracy with open sights was pretty good out-of-the-box for me also. Definitely a keeper IMHO, especially after a tune up. You may decide to add a scope before I do. If so, please let us know if that new plastic rail can hold a solid point of aim.
The trigger can be adjusted to be short and crisp. While I really disliked my trigger as received due to poor factory (or first owner) adjustment and RUST, I think it became one of the best non-Quattro triggers I have. Adjustment is actually easier than the Air Hawk Elite 2. You don't have to completely disassemble the rifle & trigger unless something is broken. If I can get some free time this week I will try to post some images of my adjustments. I would like to adjust my trigger to be short and crisp as you say. I'll try that first but it is pretty loud I'm thinking I will need sometime in the near future Disassemble to grease the spring.If you DO want to take apart the trigger for sear polishing (probably NOT needed here) you will have to use a spring compressor to remove the rear trigger block & spring retainer.I need to make a spring compressor, do you have a photo of yours? I can fabricate just about anything, I can weld, mig & tig and I'm also proficient in woodworking. It would be great if you could post some images of your adjustments. And if its easierthan the Ruger Airhawk Elite II is must be simple. I actually made the adjustments you provided on the Ruger to not only my rifle but a friend's as well.
I documented my AirTact trigger adjustments and was planning to post all of it here, but the size of the post was approaching the GTA limits. I also wanted to put images inline with the text. To that end I started a Wordpress account to publish my results. My first post is rather crude, but I'm new to Wordpress.Here is a link...https://michaeljbernard.wordpress.com/2019/03/23/2019_03_23_airtact_trigger_adjustment/
