Hey ASC,

I'm doing a Mk18 mod0 CQBR setup for a friend. His primary is currently an ICS CXP 08 with a Madbull Double Star Corp body (link: http://www.airsoftgi.com/product_inf...oducts_id=6254).

I'm not familiar with the CXP 08's RIS mounting system.
As far as my educated guess goes:
1) ICS uses imperial threading on the upper receivers and barrel nuts.
2) G&P also uses imperial threads on their upper receivers & nuts.
3) My Madbull Spike's 9" RIS fit perfectly out-of-the-box on my G&P body.
4) This guy's body is Madbull.
5) His CXP front end fitted fine on his Madbull body

:. Therefore, if Madbull barrel nuts fit G&P uppers, G&P delta rings should fit on his Madbull upper.

I do not want to proceed further until I get clearer info. I've looked up Madbull receiver threads but found nothing. If anyone here knows, please help me out!

Cheers,
Moose
