i would hardly call it a blowback, just the fake bolt moves back and forth get an AEG get UKARA'd and if your still after blowback get a Gas M4. Kingarms would be my choice also.
I agree with most of this (I have no idea if KA M4s are the best, as I've never seen one in the flesh, but I'll trust Matt here :lol: )
I'd honestly avoid AEGs w/ blowback like dangerous levels of radiation.
I have yet to be convinced that it is possible to have blowback on an AEG without causing mass and huge failure to your gun. Unless, the AEG has a seperate motor for the blowback. But then, we go down the road of wasting battery power...
(If I had a quid for everytime I have said, or heard someone say "me ruddie pistons gone again!" I could have bought a STAR L86 LSW. At the orrigional UK price...)
If you really want blowback - get a GBB. When you get UKARA'd.
You'd be wasting your money buying an AEG now and then UKARA, RiF GBB (unless you have a good few years to go until you get UKARA'd) Some people will not two-tone a GBB for you, as
they believe the paint can somehow damage the gun's workings. I doubt this, but I'm not a gun smith.
Some people do sell the gun parts on their own - such as upper recievers for M4/M16 types in forums, under gear/spares/parts, although I don't think anyone is currently on here.
