I recently bought a boneyard Double Eagle UTR.45 off a sales discord.
It was advertised as not lifting BBs, and being full-auto only.
A simple enough fix, I assumed; worst case scenario, with the Falcon control system I can hopefully just set it to fire one shot on all the settings and use it like that. (I rarely use auto, so it's no big deal if I have to)
Alas, on receiving it that's when the issues began.
It wasn't packaged brilliantly (I've seen worse, but it's still fairly loose inside the box, And I'd be embarrassed to have done this, personally).
There was no fire selector of any type, not even loose in the box, which gave me my first uh-oh, as setting the FCS requires using a fire selector.
Then, on taking it apart, it has a jefftron MOSFET installed, which I'm assuming is *not* standard.
From what I've seen, the stock one has double eagle written all over it and looks different.
I've never opened one of the new FCS double eagles, so have I basically been sold a problem child without being told?
My guess is that the previous owner watch some 'top-tier' YouTube review and thought that replacing the perfectly usable FCS with something that is cool and shiny looking according to "Big Baz the internet tech" was completely necessary before realising they don't know what they're doing, losing several important components and just selling it off cheap to some mug (aka me! 😅)
