As someone pointed out in another thread, KA is coming out with both a MUR and a full VIS-1 upper. Presumably it'll be made for their own lowers. But if you're swapping the entire receiver it's worth keeping in mind as an option.

as for larue rails...will they fit to either the hurricane or dytac uppers? if not then how does that madbull kit work? ive seen it before but i havent got the slightest idea of how it works.

The barrel nut (the actual nut portion of the delta ring which screws onto the receiver) is the same size, physically, between airsoft (the "realistic" type ones, like G&P, KA, etc) and real steel; however, the thread pitch is slightly different.

Given that airsoft receivers are relatively soft metal, I've seen some people advocate just forcing it on (example here). If you have a real steel armorer's wrench, I think you could generate enough torque to pull that off (although I'd make sure the threads are well lubricated before attempting it -- for the record, that link was for the sake of citing an example. I don't recommended following his advice).

Anyway, the Madbull thing is a die. It allows you to recut threads. From what I gathered from it, it's to allow you to mount real steel parts, but their product description is extremely vague, and I haven't really found any reviews or comments about it.

magpul pts ubr...im all over that. i just really liked the look of that stock. Ive been looking all over but i cant seem to find any official magpul pts site. i always find airsoft retailers with their products.

thanks for the help guys...i really appreciate it!

Yeah there's no Magpul PTS website. The PTS CTR stocks are the same as real steel, and the MIAD grips are made by Infinity MS (in HK) who also made the airsoft versions of Falcon Ergos etc. (under license).

Magpul doesn't even really list the real steel UBR on their website yet, so who knows when that'll actually come out. They seem to have manufacturing issues. I noticed the MASADA project was being partnered off to Bushmaster now.
