The Brass Eagle Eagle (Yes, Eagle Eagle) was perhaps Brass Eagle's attempt to be first to market with an inline blowback. Even if it was in fact the first, its time on market was short lived. The design proved to be so unreliable that Brass Eagle took them back, and converted them to Nightmares. The tiny Nightmare valve, while famous for its hammer bounce and 'brrraaaapp' sound, does not reliably blow the hammer back. The trigger mechanism is also incredibly uncomfortable and requires excessive force to use, appearing to be hand cut modifications of the stock trigger to attempt and create a floating sear. The angles however are off, and pulling the trigger pushes the sear rearward just as much as it trips it, putting the force of the rather stiff hammer spring on your trigger finger.
