M4 build, boring, I know.

EDIT: Had a look at receivers on http://www.wgcshop.com/wgc2008/main/ and found a VFC one that has perfect markings, do you know if it's compatible with G&P? Also, what's the difference between the one with the longer bit out the back and the one with the shorter bit? If you know what I'm on about?

I think you mean how far back the forward assist is sat? Traditionally it's right at the back end of the upper receiver, on the right side. But newer designs have put it further forward.

I'm not sure of the reason for this, it might be down to better ergonomics or something. I'm not sure whether it'd be authentic to use a receiver with it in the more forward position if you're going for an M4 (not the A1) either. Are you going for authenticity, or just something slightly unique in a subtle way? I'm guessing authenticity by your willing use of Ares parts lol.

I doubt it'd fit and the cost would be high but I know for a fact that there's a Systema M4 receiver that has burst markings and no airsoft manufacturer's trades.

Aside from that I think I've only ever seen M4 burst receivers done with the H&K style fire selector markings. There's a seriously swish M16A4 burst receiver with all the real FN markings on it though, I was going to get one for my M16. The M4 might share the lower half to get the burst mode? I doubt it but it might be something worth looking into.

He was talking about the receiver extension, the tube at the far rear of the receiver that goes into the buffer tube.

Ed, if you really want an FNH receiver, why not get a blank one custom engraved?

Yeah that's the part Marksman. Ed, I've found an M4 receiver with burst and real trademarks engraved now, just compatibility and colour I'm concerned about :L.
