They are generally speaking, the marketing wank and up-selling via youtube personalities who have a financial interest on mods (esp involving slugs) is what gets us/me. The most precise and consistent I ever had my m3 was out of the box, then I had to go chase slugs and 70+ ft lbs in 22. Fx out of the box shot 18 jsbs perfect without a hiccup, thru the same hole at 60 yards. Aea out of the box burped 18s backwards, broke a probe and extruded an o ring on the front of the air tube before the first 500 tin was shot up. My benjamin 392 didn't have a problem for 25 years, whereas my 25mrod was cracking valve pins and losing guage block orings within a couple years...... And every 24 months after that.
I have no particular brand loyalty, i will call out the mechanical defects on all and especially the hard upsell on parts and upgrades on fx, as well as rolling upgrades I had to pay for.... that people didn't 5 months later for less money. (that's a different thread)
My continued contempt for the aea hp series, specifically the hpss I own, is the manufacture corner cutting and assembly qc for a fairly robust price point, EAPECIALLY the lack of repair parts, all things considered. Which I didn't suffer on my old crosman group products or my insanely priced fx impact.
The aea hp series is not a bad gun if you have the ability to fix, make, or find parts. It's just super annoying theyre over $300 for the quality I got.
