Which one? Both seem to work for me.

those chrony readings do look suspiciously high for such a stubby barrel though...
I thought so to at first but I think I did enough tests with similar enough results, I have like 30+ videos of it being chrony'd; I only put in the last dozen or so that I filmed with my brother's camera. Like I said in the video, I'm a lot further away from the chrony than it seems.
I wrote this post about 6 hours ago but had uni and decided to wait until I could come back and do more testing. I just went up to the garage and did three quick tests all from a distance of about 1m. I got three consistent results between 610-660fps. The high speed suggests the condensation shouldn't be interfering at 10" away and I think these tests from 3' make it conclusive enough for me. I got two or three readings above 800fps back last week when I did the bulk of the testing, I of course threw those results out as too optimistic.

That's really cool, how is the CO2 inflator? Can you tell how much pressure you put in?
My instructable already got 'featured'
The CO2 inflator is pretty cool, I can't tell how much pressure I put in the gun though. GGDT suggests that with such a short barrel, 800PSI of CO2 will do little in terms of performance compared to 350PSI of air; so not even a chrony reading could give me that much of an idea of how much CO2 I have in the gun when filled from the inflator.
Also, small nitpick, the trigger could be a little more discreet.
Like the one you sent me on the pengun? I actually used that for a bit; when I couldn't be bothered screwing my adapter on. I agree that my adapter could be smaller but I couldn't work out how to make it smaller from the fittings I had and it had to have three attributes:
1. It could thread on or attach in some way
2. It had a return spring for the bolt
3. The bolt was prevented from falling out of the adapter
I've been thinking of hacksawing off 75% of the threads on the adapter so I can screw it on quicker but then that risks me screwing it on and the bolt pushing down on the schrader and firing the gun.
