So here are the three sets needed for each gun.
Look closely at the engineering which has gone into each pedal. It's VERY strong. A nice deap channel runs around the shaft, where i gather grease is provided. You also see the small hole right through the centre of each channel, affording better lubricant movement.
Now look what has occured to the hole through the shaft shown above. The hole has clearly been distorted by the twisting of the shaft at the weakest point, right through that hole! HOW MUCH FORCE WOULD BE NEEDED TO DO THAT!! Incredible. It's not a problem for me, because it doesn't impede functionality, but I can't get my head around what must have been done to this little piece. You will also note, there is absolutely no damage to the flat of the pedal itself. Why? Surely something that damaging would have left some trace of impact damage to the pedal surface, but there is nothing at all. Fascinating.
