KJW M9 Rails

Does anyone know if the rails on this M9 are normal 20mm weaver rails??? I believe they are but it doesn't have the normal grooves on the rails, so I wanted to make sure. I know very little about rails and mountings so any more info on them would be great...

They should be, I have a rail set that connects to the gun and gives you more rail space on the top and bottom of the gun with space to put two more rails on the side if your interested. So you can mount a flashlight, optic and all kinds of other crap if you are so inclined.

Alright, thanks.
Can you give a picture of what your talking about? Cause I may be interested.

Yeah, I'll have it up later.

Alright man sounds good, Thanks.
