Secondly, I hardly think that shaving a few grams with make much difference, you're better off tinkering with the hammer spring which is set up to be very strong for CO2, much more than a 150% spring for green gas. If you swapped that out for a regular TM spring or a 150% Guarder spring, I'm positive you will get better gas efficiency with a reduction in kick.
Lightweight BBU's are for very light slides and the KJW is anything but. Not to mention I would be very surprised if it fit without modification, KJW tends to have different tolerances than TM, and those are all made for TM guns.
