I'd call the performance on propane/green gas pretty abysmal. Two 3 round bursts and the sluggish cycling gets like 50% slower not to mention the drop in FPS.

Will any of the internal upgrades fix this or should I just ditch the propane mags and get some CO2 mags?

Also before someone tells me to lube up the internals, I disassembled the gun and greased it thoroughly.

^nugent made a video on what you can do to have a game able mp5. Look him up on YouTube.

Thanks that actually helped a lot. I've already got the guides on order but I put a spacer behind the buffer spring like he showed and that upped the ROF and the overall squishy feel.

I'd like the know where to find the 2.6mm high flow mag output vales though they seem to be OOS on WCG.

Sluggish issue should be fix for all new gen2 mp5s, I have gen1 SD and gen2 A3, unless you are getting a very old gen1....

By the serial numbers.

If you look back in this thread someone posted which gen matches up to which batch of serials.

Hi all,

Wondering if you guys can help out a fellow member that I sold a VFC MP5K to recently. So prior to shipping, I tested functionality again with both semi and full auto working flawlessly.

So they got it today and said that the selector can be rotated completely around over and over and it's mushy? Didn't notice these issues before, but should he be worried or is this common behaviour? Can someone try? :-p

[N_Force]

That is normal and how it rotates and to be removed for the trigger box. If you rotate ot gently, it should be stop by a metal ball lock if I remember it right. No big deal

Just wondering, this isnt exclusive to just the GBB version but the AEG as well. Is there a way to make Mp5's HK slap ready? Is changing the charging handle to a fully metal one be enough?

I've HK slapped my VFC since day one, nothing broken.

Completely normal, the selector can be rotated so it can be disassembled from the trigger pack.

I fully slap the VFC gas gun with no issues.

I did snap the zinc handle on my TM and I replaced it with a steel guarder one that is as solid as they come.

+1 you could always replace the handles to get the HK slap feel lol on the AEGs.
The GBB mp5 from vfc comes slap ready.
