Still have a little work left to do, One thing is that with this barrel I have to find the right pellet, The best pellet so far was the H&N 21.4gr 5.53 I did use about four different pellets on this outing. The trigger linkage on the bullpup I rethought it, and it feel just like the natural trigger, I like that. Not heavy well balanced, and looks great.I also have to make a sleeve for the barrel to fit inside the barrel and air tube band which lends no support. Then I will send how the 50y and 100yard groups will act. Overall with a few mods it should be a very nice set-up.. the wood is very nice.....a must have for the AT-44 if you just want something that you can whip out with accuracy.
