Hi, Since my TM M4's been not doing so well, I've decided to do a All-Round upgrade to it.
The thing that I like to start off is the gearbox. To be honest, I have done a lot of dry-firing before, and that might have probably worn out the stock gearbox, more or less. And with all the jamming, I've learned my lesson.
These 2 Systema Complete Mechbox are what I have in mind
SYSTEMA Mecha-Box (Gearbox) 1J (High Speed)
SYSTEMA Mecha-Box (Gearbox) M120 (Torque Up)
And then moving on to the barrel... and hop up sleeves(and of course the rubber)
Deep Fire SS 6.04mm Barrel
Guarder Improved Bucking
Outside Accessories:
5000Round Box Mag for M4-M16 series(Already Purchased)
JBU F8R Tactical Rail for M4/M16 Series(RIS)
Action Armor Rail Panel Set (Black)
And some random Foregrip, probably those "Bipod" integrated ones from HK Ebayers.
If you guys have any advices, I will be very glad to hear it, since I haven't done ANY upgrades myself before.
Thanks, I know I've made alot of threads needing help but, please put up with me
