You could cut down a 300mm but ensure there is no deformation in the end, and crown the barrel with a file so that the BB breaks away freely. You're better off buying the proper length barrel.

You will need a cylinder with a hole halfway down the shaft so that there is a proper amount of pressure on the bb giving it the best fps.

A silent cylinder head is practical but only with a proper piston head, get them as a kit like the Systema Silent set. Otherwise:

Modify is great, go for a polycarbonate piston head with a bearing.

This is all my personal opinion, but I've built a similar system and it is great.
