Hello
I've recently carried out an upgrade on my stock Specna Arms SA E08, upgraded to 13:1 shs gears, XT high torque motor 22TPA, new piston heads, costed around 65£, motor was only 30£.
It was absolutely worth it, trigger response was amazing even without precocking. With precocking, the shots are almost instant. Though i haven't tried the gun in a full game day yet but everything has been working well so far.
Mosfet, im using Perun ab++.
I'd highly recommend buying parts from ak2m4, the XT brand parts are super cheap but also of good quality and also cheap next day delivery. The customer service is amazing, the guy will give you as much help as you need and answer everything.
