Upgrades for Bim4 series Dboy M4

Apr 2, 2009 12:31am
Hey, I bought a new Dboy M4 Carbine model BIM4 Series. I have put an aimpoint scope on it and I hope to buy upgrades to make it more powerful and more accurate. Any suggestions on what parts to buy?

I think with DBOYS/ BOYI full metal series AEGs, you pretty much need to spiff up the internals because what you're paying for is essentially the body. I'd say the works such as spring, bushings, tightbore, and if you can afford it, a gearbox. I know a friend who has a S-System by BOYI and he dropped in a Echo1 Gearbox and it runs great. Hope I've helped. 8)

yah the helps alot! i have the metal body edition and it said that it shoots 400 fps, but i have never personaly got it chronoed. how much would it cost to upgrade the internals roughly? i only spent $149 on the gun and i want to buy a pistol. should i upgrade it or buy a pistol in your opinion?
