Project :MP40 upgrade

Considering upgrading my MP40,in the light of latest game flaws noticed.Based on a UK airsofter mate advices,what it needs is as follows:

Upgrade choice # 1

Strip the box, clean everyting, it will be full of lithium grease, clean it all off, including the piston / cylinder, re assemble fitting the following new parts, metal spring guide with bearings, a new piston & piston head, I recomend the TM standard type piston & a systema area 1000 piston head ( without bearings, its cheaper & lighter ) systema oiless bushings, you will have to re shim the box too, re assemble & re grease using lithium grease sparingly on the gears / bushings, on the piston use silicone grease, I recoment marui silicone grease or systema silicone grease as the UK avalable grease Servisol & Abbey are too thick & cost you FPS, for a main spring go for a PDI 150% spring.

His opinion on the aforementioned upgrade #1:

  • Did any of you try to replace the nozzle? I think this is the "weakest" part in the gearbox. I experimented with replacing many other parts like, spring and piston but did not get a significant improvement in performance.
  • Still you will need to exchange the nozzle, it easy to do and should give much better performance. At least on my MP40 this must be the part that causes some problems (already tried to exchange most of the other parts).

I had my agm mp40 upgraded by fire support and what a amazing job they did. The parts they fitted are as follows:

- v3 bearing spring guide
- tm piston and piston head (standard)
- area 1000 cyclinder
- area 1000 cyclinder head
- area 1000 metal bushes
- tm ak hop unit
- tm mp5 inner barrel
- guarder sp90 spring
- guarder improved hop rubber

they kept the original nozzle as the original is fine. with all that she now fires at 315 fps and has amazing range. a few people on here have had this work done by fire support and are all pleased with the outcome. i had extra work done on the motor cage so a eg1000s could be fitted and now the rof it great on a decent 8.4v mini battery.

I wonder if anyone would be willing and able to help with this project.I'll see what and who.
