This is the second rifle I have purchased from AOA and I could not be more pleased. My Commander arrived complete with chrony test results which,after mounting a Hawks 4-12x50 and using jsb 25 Cal 33.95 gr. pellets, I was able to match. After some additional pellet testing at the outdoor range I find that this rifle prefers the jsb King Heavy 33.95 Mark II best. At 50 yds I'm getting a very tight nickel-sized grouping and now using the Mark ll pellets an additional 15 fps on the chrony. At 75 yds the group is just as tight and I must say that the energy must be present because the shots broke the tack welds on my resettable squirrel. I'm getting 85-90 shots per 250 bar fill so there is plenty of air for this style platform. For the most part this rifle is very high quality and accurate and I found only one slight disappointment. The finish on the barrel shroud seems to be lacking in the quality Department. For me that is not a big deal since I plan on changing the finish anyway and according to airguns of Arizona that will not violate any warranty
