Technical characteristics of each kit part:
 
Gas spring (GasRam)
A gas spring is a pneumatic spring similar to a shock absorber. It consists of a steel tube with nitrogen under pressure, and a massive rod, which when entering the tube meets resistance to nitrogen pressure When the gun is cocked, the GasRam rod is pushed into the tube and consequently increases the pressure inside the tube, storing potential energy and acts as a pneumatic accumulator. The advantages of the gas spring are the capacity to keep the gun cocked and ready to fire for long periods of time without spring fatigue, no torsional torque (caused by the expansion of the coil spring) that is exerted on the gun, recoil pattern smoother and faster lock time (the time between the trigger activation and the lead exit from the airgun barrel), resulting in more consistent shooting accuracy. Gas springs perform more reliably in cold climates, as the grease used to lubricate coil springs tends to thicken at low temperatures, making it difficult for the gun to function. Gas springs also have less lateral and longitudinal vibrations than helical springs, so they are generally less sensitive when compressed, making it easier to obtain consistent groupings of shots.
Piston retainer (PU seal)

Elite Airguns PU seals are produced in polyurethane (PU). They improve the sealing, provide  more stable shots, with less speed variation between shots (Spread). Our PU seals are compatible with original plungers and Elite Airguns plungers.
 
Centralizer:
It is the part responsible for aligning the Gas Ram between the other parts.
 
Lubricant:
Product used to lubricate the piston retainer (PU seal), responsible for sealing and compressing the air that will propel the projectile.
