    I have fairly recently bought a G&P M4 Sopmod and i would like to know some internal upgrades for this gun that would make it better. At this moment i have no budget.

    New piston. G&P pistons aren't the best. And fix AOE, reshim, regrease and just externally enhance the crap out of that rifle.
