Marui accrssories tend to only fit Marui, as well. Might not include Beretta grips but you never really know with Marui. 
Spoke to xforce, more KEle berettas coming.
If i had the slide on the KEle sandblasted, what would be the best way to paint it.?
It would need to be fairly robust, to withstand handling, and pulling / manual cycling forces…
I think some versions of Tokyo marui GBB is relatively “convertible” to gel blasters. But I need to get the gel blaster specific parts made. Not sure if CNC 6061 is a good material. I hope their internals are interchangeable In most of their GBB.
If you could get, genuine Tokyo Mauri GBB gel blasters,
In Biohazard theme…
You would sell truckloads in Australia.
They brought in WE tech models, and they sold out instantly.
People have been asking for more, but they haven’t brought any more in.
That is why, i have mucked around, with Double Bell’s converting them.
Please, look into it…
Ok, a bit of dremel work to get the L nozzle adaptor, to fit.
Had to make the barrel opening a bit taller to fit, and remove some of the rear guides, so it doesn’t angle down.
The airsoft is intimate fit of adaptor onto the blaster, this 3d print is not.
It does have one screw hole in the bottom, so i’ll have to drill a hole into the bottom of whatever blaster i use, for retention. Also, fill it with a soft foam, to bulk it out, fill the gap, and stop any loose sloppy movements ( easy, @maiphut) !!
Like wise, the Supp is not an intimate fit, its loose as well.
I did want to have the Supp being removable, but i might ultimately have to araldite it on, when its aligned properly…
If i use a KEle as a base blaster, i’ll have the upper slide cerakoted semi gloss black, so it looks the part…
3 different grip possibilities…
1: Burton grips…
2: std black emblem…
3: Real wood/ blue emblem…
The torch i’ve used previously is light enough (boom boom), and can be supported by the 3d print L adaptor…i’ll grab one of those, for this…
Getting close…!!
Looking good! 
nice work
