compression components usually... sometimes barrel.. hopup rubber.
Cylinder head, piston head, nozzle (sometimes) around 40-50$
good hopup rubber like pdi w hold 13$
I roll with prommy barrels, so that's around 70$
spring and piston are irrelevant. Properly tuned compression and hop can lift a BB out to 50-60m Which is beyond your 150ft requirement.
A stock TM pistol using .28s can hit targets at 50m (man sized) reliably. That would make the BB travel probably around 250fps on green gas.
