Yes, probably no sense to go under 1500 psi. Surprised me it's externally adjustable. 🤔 The Huben 19cc, has not that feature.

Go ahead. If you can prove the rifle accuracy, that should be the best insurance or warranty you shall get. Worse scenario shall be that somebody touched the crown (the end oh the barrell) and that has no easy fix.

New or used? U$ 300 diference? I think that the answer comes with your abilities to repair things. Is this your first airgun? Many people that buy a gun tries to tune it to their needs, and with the Airforce, is kind of simple. But if don't have a clue about repairing things or you dislike to...

Yesterday I disassembled the top hat valve, and found 3 tiny holes. I carefully enlarge them and got 950 fps instead of 820 fps.(18 grains pellets) Good enough for the 19cc plenun. See the picture in the process before finished and polished

Most probably that's my problem.... Thanks. I'll disassemble the top hat to see how it looks like from inside.

Probably mine is not an original Huben 19cc.... I bought it at Aliexpress. I just get 820fps with 18grains, (TALON not CONDOR) with a 65 grams hammer and a reinforced spring. If any idea to get it better, please be my guest.
