Tanio Koba / KJW M4 GBBR Basic Information and FAQ

[solst1ce]

I've read here that most aeg front sets are compatible with a little modification, but what about the length of this on my KJW CQB? http://shop.ehobbyasia.com/g-p-kit-s...front-set.html

So my RA-TECH NPAS has basically destroyed itself. It no longer is able to adjust, so I'm stuck with it firing at 415fps with .25s... Guess I'm buying the Cradle one soon.

[Ghostnote]

Heh. The ra tech ones are notorios for breaking very easily. The cradle one is a little more work to adjust but is solid. They are supposed to release stanag mags and a complete bolt carrier group but I thing it has been put on hold. They made pmags but with complications on exporting since they used real pmag shells.

I'm looking for someone in the gta to do a top down hop up mod on my kjw. The heat shrink mod is great for .2, so so for .25, but poop for anything higher.

As long as it has a delta ring and is not too long it will fit.

The Madbull/Socom Gear Daniel Defence free float rail systems work beautifully.

[Saberwing]

Any AEG front end can fit with a little modification, however most don't need it. I've had a G&P RAS, and Madbull DD on mine and both went on beautifully.

Well my plastic lower cracked bad today. I hope my metal bodied one arrives sooner rather then later. Anyone have a spare plastic lower they want to let go for cheap.

[audi_bhoy]

Baker_Jeff might have some in stock, check with him.

I am still looking for a metal one, where did you get yours?

[Saberwing]

Just got my Madbull Daniel Defense 10.3" Outer Barrel. Now I just need my QD Silencer and MBUS from Huang

[PHARAOH]

so is there anyone in canada that is selling a metal lower for the KJW yet? if you know where i can pick one up that would be great.


please respond via PM

[Ghostnote]

I am looking for a metal lower as well if someone can source one/some. It is probably hard to find since the price difference between the cansoft and full metal guns is much less than the average price of a metal reciever on another system. That and I'm not sure kjw sells just the lower.

I'm having my first issue with my gun. In full auto mode it will shot once or twice and then the trigger locks just like when you dry fire (the bolt carrier always closes). If I cock it again it will fire 1 or 2 shoots and then lock again. The gas pressure in the magazines is high.
In semi SOMETIMES it shoots about 6 shots (each shot weaker than the last) then locks. After I cock it again it will shoot, the first shot will be strong then the rest weaker kind of like when it cycles it doesn't collect more gas, only when I pull the cocking handle does it have a strong shot. Sometimes it will only shoot 1 shoot per cocking in semi.
Also I can feel a spring vibrating when the gun locks.
Any clues?:banghead:

UPDATE: The exact symptoms are the bolt carrier stops working after the first shot and doesn't slide. If a BB does shoot out on the 2nd and 3rd shot it's from the remaining gas in, I think, the receiver. Same problem in semi and full.
