M203 fitment on Marui M4 GBB

[FB-63]

I'm looking to fit an M203 type grenade launcher (Barrel mount not RIS) onto a Marui M4 MWS, and I've seen a bit of chatter regarding differences in the Marui barrel attachment to the receiver. Does anyone here have any experience with this? My Cyma M203 came with two different mounts for the Delta Ring....is the second one for Marui guns?

Marui MWS is real-spec so it'll fit.

Thanks for that.

Unfortunately it is clearly not Real Spec!! Nor is it Marui AEG Spec as I have bought a Cybergun M203 Kit with Real Spec, Marui AEG Spec, and Rail adaptors, and I'm having to have the Real Spec Mount significantly modified and milled out to get it to fit as per the Real Steel item.....It will be great when I have it finished and will compliment my G&P Magpul setup nicely!
