From the seller; looks like it was a worn hammer.

"All good to go I replaced the sear and recoil spring and had the same results you did. I replaced the hammer and hammer spring it runs fine now I actually think it may have been the hammer (wear) but I'm including the replacement recoil spring as the one that was in it is about an .75"- 1" short in my opinion... Sorry for the inconvenience.. I'll get the trigger group and spring in the mail Tue after Labor Day."

Have you checked the piston retainer for looseness?
Aquila may be underpowered for your carbine as well. Try some PPU or Remington.

There is only a 5% difference between Aguila and Remington.

A: 1900fps/882ft-lbs
R: 1990/967

And that 5% may make all the difference in driving the bolt back farther for the hammer to engage the sear.

I re-read the OP and this is caused by the sear not catching the hammer. Working the slide by hand it will.
If the bolt is going back far enough to extract the case and load a new round. The bolt is pushing the hammer back far enough. Bubba could have tried to lighten up trigger pull or playing with it to "go fast".
Replace the sear, would be my opinion.
I am not an expert by any means. According to post 12 (above), the bolt is pushing the hammer back far enough.

I will not claim to be an expert either. However, if the hammer will engage with manual retraction and not with firing, it could be the hammer itself is not being pushed down enough on firing, because the bolt is not traveling the full distance back, but enough to eject (all that requires is the case clear the receiver bridge) and pickup the next round.
For example, in the AR15 one can fire and the next round load, but the bolt never travels back far enough to allow the bolt catch to engage on an empty mag. Same idea, the bolt is not coming back far enough.
Let us know how the next range session goes.
