I can almost assure you that the reason you see AEAs for sale so often is disappointment from buyers with inflated expectations. I would not recommend AEAs to airgunners spoiled to (much) higher sophistications; nor anyone that doesn't ENJOY eeking out great potentials from hidden gems.
My .30 AEA Challenger Bullpup is (now) at least as accurate at 100 yards as any airgun I've owned (over 500).
Among the best airguns modern manufacturing can muster that I've owned, that cannot outshoot
The Beast are- .25 Delta Wolf, .22 Red Wolf HP, .30 FX Boss, .25 Kalibrgun Cricket, .25 AGT Vulcan 2, .22 AGT Uragan, .22 Brocock Bantam Sniper XR, and probably a few I'm forgetting (likely on purpose). My .30 AEA required very
heavy-handed airgunsmithing techniques to CONSISTENTLY OUTSHOOT aforementioned high-$$$ diva-guns, and the diva-guns haven't responded to virtually any level(s) of coddling.
If I could massage the AEA trigger closer to the near-telepathic let-offs of the divas' triggers, rather than the crisp
two-pound lightest break I can achieve...
I could sell all my diva-PCPs and buy a Ferrari!
