Thank you all for your replies, advice and information.

Here is what I plan to have installed:

-Prometheus 6.03 tightbore barrel 420mm length (I plan on using a shorter outer barrel in the future)
-King Arms Reinforced Aluminum Barrel (shorty)
-Prometheus MS110 non-linear spring
-metal bushings
-Prometheus POM piston head
-Guarder stainless steel cylinder head
-Deep fire nozzle

Does that sound alright? Will there be compatibility issues between the guarder cylinder head and the prometheus piston head?

Thanks again
