all that u really can do is get a better barrel, lighten the trigger pull, and get gas upgrades, i.e. Xchambers or regs, but its not really worth all the money to upgrade it alot, a barrel and trigger job and MAYBE a xchamber tops. since its not a popular gun not much is made for it.
We are sellin the model 83's for 30 bucks and we've sold quite a few of em. We haven't had any complaints except for one that had a broken pin in it. I still haven't shot one but i guess they don't shoot bad, or we'd have a bunch of people returning them.
i bought a point zero 83.. it came with every thing i hvent had a problem yet it shoots greatand i smoke kids with tippmans and spyders. It was well worth the money im running a remot and i bet i could beat any other semi
