2 different Gun options come with the kit,molded one piece and the upgrade PE. Of course I went with the PE, first I drilled out the muzzles and managed to blow the side out of one. You can see in the picture one of the solid molded guns donated a new one
Next I annealed the cooling sleeves to make them easier to roll
The instructions called for a 2.5 mm bit to roll the sleeves,but they would'nt slide over the reciever, Checking against the solid molded ones this was too small its actually 2.8, not a huge deal to correct
Taking my time and using some medium ca the sleeves went on nicely
