Galaxy MP5K issues

[Manni]

Ok so I broke a rear section of the upper reciever so im replacing the upper reciever with one i am waiting for in the mail (Need strike to end). So the plan is to replace this (Getting a gun doc to do this, if i can find one) Since I have it open I decided that its time to look into a few issues that never affected the gun too badly but should probable be fixed.

I was hopeing i could get some idea of parts i may need for the issues below to try to fix the issue.

1. Gun is 3 times as loud as any gun ive heard fire.
I figure this is just a reshim job that needed but any advice would be appreciated.

2. Gun randomly fires with a sharp curve to the BB.
I've seen posts on this before and it appears to be the hop-up rubber So im buying one of those.

So below are the parts I was looking at getting some advice on if these parts are needed or any good would be appreciated also any additional parts you reccomend (With reason why) would also be greatly appreciated.

1. Modify Stainless Steel Shims Advanced Version
2. Guarder Clear Hop-up Set
3. Modify Synthetic Long Life Gear Grease w/PTFE
4. Modify Air Seal Nozzle - MP5K/PDW


(Number 4 is because i heard the nozzle on this gun has air leaks so hopefully this helps)

I was also looking at wanting to switch to a p90 tightbore but dont know what mods would be needed on this gun (Short of using a silencer to hide the inner barrel) Any help here would also be appreciated ive already added the 11cm silencer and played with just that and like the look and length.

Just so you know, the Upper Receiver is prohibited to import.

I am aware of this i bought it in the classifieds

1. try reshimming
2. clean your barrel + new hop up rubber. Do not use silicone oil on the rubber.

I agree with your parts list.

Good luck.

Almost all AEG inner barrels are the same (with the exception of some like M14 and maybe L85), so it would be a simple switch.

Well that part I understood the Barrel will fit perfectly but doubleing the length of the barrel will probable drop the FPS and the gun ony shoots 320 aprox so what parts would be reccomended for more power? Or is it needed maybe im wrong here.

An increase in barrel length would raise the FPS, not drop it.
If not raised, then it would stay the same.
