GBBR (Gas Blow-back rifles) and HPA replicas (High Pressure Air) are primary replicas that operate with either Gas, CO2 or pure air, as opposed to AEG replicas that operate with an electric system. Gas-operated replicas can provide great sensations thanks to an improved realism compared to AEG replicas.
The degree of realism allowed by gas systems is due to the blowback system that is inside these replicas. Blowback allows a sensation of recoil when shooting, that mimics what you can feel when firing a real firearm. Refill your GBBR replicas with gas bottles of CO2 cartridges.
As for HPA systems, they need air tanks to operate. These air tanks can be refilled with an air compressor. HPA system offers airsoft replicas a much improved reactivity, a good rate of fire and high reliability. Find all the accessories to use your HPA system in the best way possible with items such as valves, regulators, connectors...
