Have any of you guys tried to up the fps by changing the rocket valve spring to a harder one?

Is the gearbox for this gun already out, am having a difficult time sourcing it.

The Olive Drab version is out, am actually contemplating on getting one even if gearbox is a pain to source.

Use a very weak flute valve spring!

Hmmmm, come to think of it the SD is the better version since barrel can be longer due to supressor shroud, not to mention the battery space is slightly bigger.

Looks like ICS used their existing upper and lower gearbox for their AR series, available years ago. Was thinking incase there is an epic fail on the electronic burst switch, we can still use standard switch for version 2 and maybe swap it to a standard MP5 trigger. Simply put its a safe buy, wont be a wallhanger when things go wrong.

Try to use the stock nozzle parts sans flute valve, that may eventually do it.

Man I am stumped at your situation sir, and to be honest I find it a bit amusing, hehe. Ok let me think about it and would get back to you when I have something else in mind.

I believe it can be done because that was my problem before, my gun not cycling properly. My agm sans flute valve was running 640 fps on propane, but bcg travels only a few cm backwards, not enough to cock the hammer let alone loat a bb round. Experiment with using a smaller o-ring at the back of loading nozzle. This will make your setup less efficient since it vents some blowback gas out of the chamber and pushing the bcg less backwards. It may not be optimal but at least you have a bolt action rifle in the end. Another thing is to add a spacer on your buffer tube, or make the buffer spring s

The parts you removed is correct and are the ones was referring to. Actually am not that much surprised since we have discovered that taking out the flute valve in some cases would not have any effect on the normal cycle of the gun. I believe that in some cases the sealing inside the BCG and loading nozzle is tight, meaning you have an efficient setup - hence BCG still cycles. Have you tried using only 134a gas? This may be too weak to fully cycle the BCG. OT: Not wishing anything bad to your gun but the stock charging handle of AGM is pot metal, you may eventually break this since you ha

Correct sir, sorry I did not fully comprehend your first question about the bolt action requirement. Anyway since you require a bolt action rifle, then what you can do is take out the flute valve inside the loading nozzle. This will still move your BCG (Bolt Carrier Group) rearwards but may not be enough to cock the hammer and even load the next round, hence necessitating to pull the charging handle fully everytime. Although taking out the flute valve dramatically increases your fps, so you may need to use a lesser gas like 134a to be playable.

An AR is not a bolt action rifle in the true sense of the word sir, but you can surely convert this to a semi auto gun. Just remove the full auto disconnect.

Took me a couple of months of figuring out, experimenting, not to mention several failures before it finally worked flawlessly. As for giving out the actual dimensions and solutions to niggles, hmmm. Let me think about it.

G&G made the right decisions on not using those awful capsule shaped bushings on the spur gear, G&G gearbox material is one of the best, plus their scew hardwares do not easily lose its thread. The F2000 is the easiest gun to use on the field, even if it looks awkward to some. Seems to me that those fixes pointed out are really not that hard to make, and I agree that the hop chamber has improved dramatically over G&G's earlier versions for the M4. Am just waiting for the Olive Drab version to come out, since the black version is my second choice. Too bad G&G did not have real

The MP5 is one of the must haves on my airsoft arsenal. It is timeless and even if its 40 years old I still want to hang it on my wall. The stamped steel receiver is what I really am after, those alloy receivers so prevalent nowadays just don't do it for me.
