Great! Thanks for the response, gonna get myself one then :D

Elastic broke today... :(

Replace it with some bycycle inner tube

Where can one find said innertube?

Canadian tire or any other place that sell bikes hell i would even try wallmart

Is there a certain size I should get or are they all the same size?

By the way, a spring fell out when I took my magazine out after the elastic broke... No idea where it came from, can anybody identify it?

That kind of looks like the spring retaining the piston assembly to the bolt carrier, correct me if I'm wrong !

I've spent the past 2 days looking for good KJW M4 parts but I don't really know what fits.
Its my understanding that all Magpul stocks and all Magpul non aeg grips are compatible?

What about this stock and grip?
-MILSIG SUPER STOCK http://www.milsig.ca/store/index.php...products_id=38

-ERGO Grip http://www.ergogrips.net/item-detail...TOKEN=41120939

I know the ERGO Z Rail Two Piece Replacement Handguard Rail System (http://www.ergogrips.net/item-detail...TOKEN=41120939) will go on but is there any heavy modding that needs to happen to make it fit properly?

Since that's for a paintball gun...I'm going to say no.

ahh but it looks so nice. thats ok. what else? are the ERGO grips OK? Who makes stocks for the KJW besides Magpul?

I think I found a suitable replacement. http://shop.ehobbyasia.com/star-m93-...gbb-black.html
If it fits a WE it fits a KJW right?

No, that stock probably will not fit.

Any AEG M4 stock WITHOUT a buffer tube replacement will work.

So took the gun apart yesterday after getting back from exams, and all that was inside the piston cup was a little black circle with a dent in it, and the long screw that goes across... I want to buy new parts, but everywhere seems to be out of stock...

Then the spring that fell out was the valve spring.

has anyone has any experience with ERGO grips? will any grip for a real M4 work with the KJW M4?
