I've decided to sell my brand new (never shot) AEA Challenger Pro in .22 caliber. This is a replacement rifle, my original rifle developed a leak and rather than repair it the dealer sent me a new one. This rifle is a beast, it can easily shoot any weight slug or pellet you want. The manufacturer claims it can produce 100 fpe and I believe it. I tamed my original rifle by swapping the HP spring for the "standard" spring, which is shorter (included), closed the transfer port 66% (using the simple knob), and adjusted the regulator to 125 bar. The result was the 56 shot string you see in the chart attached. Accuracy is very good, it will easily do 5/8" groups at 50 yds. I'm also including a barrel band and DonnyFL suppressor adapter (a $90 value). I'm asking $750 plus shipping and accept PayPal.
