Ooops, can't remember if it was loose but it was installed on the correct side. I noticed a little foil or filter thing inside the fill port. Anyone else have the same thing? I was able to get air into it and it held. Shots in my house at 10yds were spot on. Will take it out with a chrono on Monday to test out my JSB 4 sampler pack.

That's a check valve, it's what keeps the air in the bottle. 14 grain pellets are way too light for the gauntlet 2 which is tuned for heavy ammo. I'd say 21 grain pellets should be your lightest and 25 grain and up would be much better with the factory regulator pressure. You can take shims out of the regulator to lower the pressure for lighter pellets. If you're not comfortable doing the work you could send it to Hajimoto or just about any other tuner to have this minor adjustment done. There are plenty of how to videos for Ninja regulators on youtube. It's a very simple job.
