the A-5. The system uses a series of parts that are added to the marker to greatly increases firing rate for the marker. The system uses excess carbon dioxide or compressed air from the firing process to reset the trigger and sear with a pneumatic cylinder. The system can reset the trigger with only moderate pressure on the trigger. When this happens, the pressure of the finger can immediately pull the trigger back, creating "bounce", and firing again. This effectively gives the shooter the ability to fire at fully automatic speeds. As such, it has been banned at some commercial paintball fields. Construction Continuing the Tippmann tradition, the A-5 is very durable and features a solid cast-aluminum receiver with a high-impact shock absorbing endcap. The Tippmann A5 can take much abuse as all parts are tough. The exceptions to this are the Cyclone Feed System and the Response Trigger Kit, which both have lines that snake along the receiver and can be snagged easily. The grip/trigger assembly, back plate and bottom-line hose (or direct Air Source Adapter) are held to the receiver by four push-pins that can be easily removed to allow easy field stripping. Field stripping Unlike previous Tippmann markers, the A-5 is very easy to field strip and clean. Tippmann says it can be field stripped in about 60 seconds. This is done by removing four push pins which hold the tombstone, endcap and grip frame in place. To field strip an A-5 marker: Depressurize the marker by partially unscrewing the propellant supply and firing dry to rid marker of any latent gas. Remove barrel from marker. Remove four push-pins (#1, #2, #3, and #4). Use pliers and lubricate with paintball marker oil if pins are difficult to remove. Depress tombstone latch and pull tombstone to remove it from marker. Remove endcap and grip frame; make sure the velocity screw is screwed in past the aluminum housing, now the valve and bolt assembly will easily slide out the back of the marker. Clean chamber and bolt assembly. Lubricate o-rings with a few drops of paintball marker oil. Inspect all o-rings for signs of wear. Replace any o-rings that show signs of wear. Reassemble marker and replace push-pins. Without connecting to CO2, cock back the marker and dry fire to ensure it was reassembled properly. Note: Be sure to clean any residual paint from the hopper area. If it
