D.I.Y. SAVING GAS DEVICE

HOW TO D.I.Y. THE SAVING GAS DEVICE
ON YOUR GBB PISTOL.

Want to save the gas, you don't need to add any modified parts!!
T-N.T. show you how to not sacrifice the initial speed, but also feel the savings of gas !!
This way is to cut off the gas outlet valve early.
Most direct, effective and simple, without sacrificing the speed.
No need to spend money but complete!!
This method can be used as long as there is a pistol with a gas shutoff device.
(Of course you can also modify the plug & plug spring or mag's valve etc, that's possible to save the gas,too)
Suggest have DIY ability to refer this way to modify!!

1. First ,decomposition the pistol and remove the piston assembly.
(using the WE Hi-CAPA 4.3 and WE 1911 for example)

2. Cut the filler like the photo. (we use rubber block as an example; or you can also use toilet paper+strong adhesive, waiting for hardening then a utility knife to cut flat)

3. Will cut a good filler on the piston assembly, please refer the photo. (about half of the total length of the groove, if too much will reduce the excessive gas and resulting in smaller recoil...)
