Well here it is.....now I don't know what to do and if I should even keep going.....I am kinda stumped.

I purchased a airsoft FN EGML standalone stock.  My thought was that I would use it as a base for my LMT railed M203.  The airsoft rail is not made of quality metal but would probably stand up to shots with chalk practice rounds.  The indiv. spacing on the pictinanny slots are a little short and would have to be expanded a bit.  The grip on the airsoft stock as supplied is cheap plastic and is junk....a qd ARMS grip was put on it but is too short.  

Thoughts?

I've been looking at doing this and am interested in how it turns out. Didn't Grog do this with a different stock?

I would consider just adding a MagPul RVG® - Rail Vertical Grip behind the M203.  It would give you some area to grip and mounts to the 1913 rail.  They dont cost a lot and can be used for any AR & nice to have in the spares kit.  Just my 2 cents/

It looks like it might work, but I wouldn't trust it. If you can, try and find a Spikes KAOS stock

That is the Kaos stock for the spikes 37mm. If you look, there is a pretty significant difference between the two. The Kaos stock for the 37mm takes into account the thickness of the mounting bracket on top of the spikes 37 mm launcher. The Kaos for the M203 has a thicker top section.
