Hello everyone (´-` )/
This is a front page of HK417 PTW Project.I will add more information sequentially.
■PURPOSE■
The purpose of this project is transplanting the PTW system into the VFC/UMAREX HK417 GBBR. This page will include some instructions of design and modifying for converting in near future, but now this page is under construction.■MOTIVATION■
The Professional training weapon (PTW) is one kind of airsoft guns driven by an electric motor designed and developed by SYSTEMA. The design of PTW is clever and delicate. However, Sadly, SYSTEMA's PTW lineup is just M4 carbine and MP5 sub-machine gun despite of a very compact gear case unit. Of course, especially on the M4 carbine, you can assemble and enjoy many types of setups however, these cores are still the M4 carbine. The motivation of this project is that it is pretty cool for me to use a gun that is very different from other airsofters.■DESIGN AND METHOD■
More modifications and new part design are required for the transplanting than your expectation. At first, for putting the PTW gearcase, milling a lower-reciever not only but also modifying a motor, a sun-gear and an electric circuit are needed.
Secondly, making a sleeve and an extension for the PTW cylinder are needed because the cylinder has to be larger size to insert properly into the HK417 upper-receiver. That means you have to spend labour more than your assumption to the converting.
