Today I finally was able to fill my tank for my N7 Milsim. When I began to chrono it, I set it to 80psi shooting .25s, and turned the hop all the way off (just to get an idea of where I should set my rig for its psi). The first few shots were great at 370ish, with a little inconsistency. After 5 or so, it jumped up to 412, then dropped down to 270. I sent several mags of bbs through with no change. I changed the psi to be higher (110) and lower (60) and there were still inconsistent jumps with sporadic bouts of 5ish shots of consistent FPS. I noticed that there seemed to be a little bit of lube coming out of the sides and tip of the nozzle from inside the engine and am wondering if I need to pull it apart and clean it. I called Amped Airsoft and their customer service guy I talked to said I could be pulling the trigger weird? He also couldn’t find a tech to help me so I am waiting on a call back.

Does anyone have any other ideas for me? I am running it on a AMPED Airsoft SLP tank (48/3000) and their SLP regulator.

I am not a fan of those amped regulators. The refresh rate and general quality of it are inferior to pretty much all the other regulators on the market, even the older generation ninja LPR and firebase. That being said though, I don't think that's going to be the source of your issues. The lube coming out of the nozzle and engine are red flags for me. I'd take it apart and clean it. I'd also give your bucking a good wash after that too. I have a feeling that the lubricant from your nozzle got onto your bucking and is impacting your bb retention.

Thanks, I am taking it apart right now to clean it. I have heard mostly good things about the amped regulators and figured I can give it a shot. I am not super worried about the refresh rate as with the N7 Milsim I am limited to semi-only. I'll update this and see how it goes after taking it apart.

Update #1: it is apart, lube everywhere. Not a ton like in a cheap gearbox, but a fair amount covering everything.

How much lube should be appropriate inside the chamber?

Update #2: Everything has been wiped clean, I'll put it back together, hook it up and then see what come out. I do not own a chrono yet, but am about to order one online. I'll add a pic of the grease I pulled out of the nozzle.

Update #3: have put probably 100 shots through, no grease coming out of the nozzle or area around the nozzle. I will test this out the next time I have access to a chrono to see if I am still inconsistent.

One thing I did not realize while chronoing my rifle but found out afterward while shooting it at home was that I was double feeding every so often. This would be the result of a bucking that was too loose in my hopup chamber. This would also explain my results when the FPS would dip by 100. I am ordering a new bucking soon (Prommy Purple), the ProWin HU chamber and a flat nub to get this thing shooting consistently. I also need to fill my tank. I have been experimenting with how to make it quieter, and just shooting it for fun.
