Great product, fills my KWA M11A1 perfectly.
Word to the wise: Be very careful with it on the field. I just had mine screwed onto a propane tank and left it setting in my truck. When I drove to the other side of the field and the plastic table fell over on top of it, the small metal stem on the tip broke.
I will be buying another one, and this time I'll leave it in a safer place.
Also, the valve doesn't completely close sometimes after a mag is filled. I just unscrew the adapter from the tank, screw it back on and it stops.
Great adapter, I definitely recommend!
Metal construction (will take anything except a 15lb table ;-)
Side valve for silicone
Very small stem (fault of mag fill design, not really this product)
Small leaks after some mag fills
