As stated earlier in this thread this mod can also be done with the BB gun unit as well since the two unit function similarly. However, I have not posted any pics or instructions for the BB gun mod. It is pretty simple and I think many have been able to work it out by themsleves. Regardless, one day I'll get round to it in more depth but till then here are some pics of the BB unit modded for recoil.

As you can see the BB unit is a bit 'fatter' than the recoil unit. Hence to have the servo arm swing in the centreline of the barrel the servo can be mounted on the bottom of the unit rather than on the side.
You can also see a method of attaching the block inside the BB unit with the barrel. You can use some shrink tube to attach the barrel to the protruding nipple on the block inside. In the pic above the shrink tube is red. Depending on the tank and barrel used you can even cut the shrink tube to a certain length to make fine adjustment of the barrel length.
