I've trawled the web for some time and can't find out how heavy the FWB 80 is. My guess would be about 2.5 pounds. Or is it nearer to three?

Difficult to estimate because the weight is mostly at the rear of the gun.

I actually have one, but no scales, and so I would be grateful if somebody could tell me.

And if they also knew what the weight was with both weights and plastic insert attached, I would be doubly grateful.

Kilos or pounds, doesn't matter.

I thank you.
