The overall weight of the gun is 6lbs-2oz, someone added a rubber recoil pad at some point so that might be adding a little weight. I have reached out to AYA USA and they said they would contact AYA in Spain their opinion. I’m not feeling too optimistic but it will be nice if they can give some info. I’d be surprised if they could use a high strength steel for barrels and also attach ribs and keep the required heat treatment.
