There are many things that can be done to soup up a gas gun. Not all guns are easily modified, but most are. Some of the things that can be done to improve or increase gas gun performance:
Custom subchambers - wider air channels for higher rate of fire and velocity.
Valve upgrades - increase airflow for higher velocity and rate of fire.
O rings - hard o rings reduce rate of fire but increase velocity.
Barrel upgrades - recoiler units, counterweights, tight bore barrels, hop up barrels, longer barrels. Basically counterweights, stiffer springs, and recoiler units act to give resistance to the barrel as it moves forward. This lowers rate of fire, but increases velocity and recoil. Hop up barrels increase range. Tight bore barrels reduce grouping.
Hose upgrades - wider hoses give you more airflow for higher velocities.
Since increasing input pressure also increases rate of fire, the upgrades that reduce rate of fire also allow you to run at higher pressures while keeping the ROF down to a usable level.
You can get power up valves from different manufacturers, custom subchambers, brass main chambers, hard o-rings, extended/tightbore/scs hop-up barrels, and a recoiler weight assembly. Miscelaneous valve porting, polishing, and tuning can also be done.
Recoiler weights are only for BV type guns. For JAC M16's they consist of a series of weights and an enlarged outer barrel tube. This enlarged tube is required to house the weights as they would not fit into the narrow dimensions of the stock outer barrel. The OK made recoiler weight requires you to completely and permanently cut out the middle section of the outer barrel and replace with with this oversized tube. Many claim that structural rigidity is sacrificed by doing this. The up shot is that now the barrel is much heavier, requiring greater pressure to build up before the gun discharges... More power basically. it also slows down the ROF, something that is desirable when using high pressure that would yield unrealistic rates of fire on a stock gun. Finally, the added weight adds a nice kick to the rifle as the barrel recoils rearward at the end of the firing cycle.
