3D model description

The highly anticipated MP5 Lower is here! This kit converts your AAP-01 to an MP5 and lets you use any CYMA MP5 Magazine. An HPA setup is not required; this kit also works with regular green gas magazines! This kit does not include the carbine kit; you can find it here: https://cults3d.sitegames.net/:2282956

But how does the magazine feed from the front?

A tube transports the BBs from the MP5 magazine to the chamber!

Throughout this project, the #1 priority and biggest challenge was to make it feed as smoothly and consistently as possible. After months of prototyping different designs, I achieved my goal. This HPA Lower uses a plastic PTFE tube that smoothly transports the BBs from the magazine to the chamber, letting you fire full auto without issue. If you can't find this tube, you can 3d print it instead, which also works well (I highly recommend getting the PTFE tube for ultimate smoothness). You can find more information and assembly instructions in my Discord server: https://discord.gg/B5KFRRkb8R

Key Features:
- Feeds from CYMA MP5 magazines
- Large window lets you see the BBs Feed
- BB latch holds BBs in place when removing the magazine
- Easy to assemble and disassemble for maintanace and cleaning (only 1 screw!)
- Works with green gas or HPA (HPA is recommended)

Things you will need:
Required:
1 x half an AEG M4 Spring (8 x 8 x 0.8mm)
1 x pen spring (4 x 10 x 0.4mm)
1 x countersunk screw M3x12
1 x countersunk screw M3x20
2 x M3 nut
1 x countersunk screw M4x20
1 x M4 nut
2 x countersunk screw M2x8

Recommended (but not Required):
1 x HPA fitting for we/kj gas magazine ( Converts your green gas magazine to HPA, I used this one: https://www.aliexpress.com/i/1005006750796503.html , but airsoft shops do sell this)
1 x PTFE tube 8mm OD 6mm ID x 60mm

Feel free to my server and ask me any questions before ing! Otherwise, here are some common questions I've gotten.

FAQS:

Q: I don't have an HPA system, can I use green gas magazines?
A: Yes! You can still use green gas magazines!

Q: Will it fit on my printer?
A: The parts can fit on a printer as small as the A1 mini (180mm x 180mm x 180mm)

Q: Will all the BBs fall out when I take out the magazine?
A: No, there is a BB latch that stops the BBs from falling out. There is also a little button inside the magwell that releases all the BBs.

SAFETY DISCLAIMER: Always wear proper face protection when playing airsoft, especially with 3d printed parts! 3d printed parts are more likely to break, so please be careful!
