Ok guys, I am selling the Aps2 and building a SR25 or SR16 I have all the outer parts of the gun. now I need the heart and soul of it,
what is the best way to get to my 490-500 goal
what spring? what other mods? I have a line on a CA and a TM right now both stock, I would rather get the CA due to the metal reciever.
bushing or bearing? cylinder?
I would like to keep the gear box build down to under 300.00
advise or a good website would help out
Thanks In advance guys
