RT Valve vs. Retro Valve

[mountaindud]

What is the difference between the RT and Retro Valve? I know the RT is the valve on Automag RTs and Retro Valve is the upgrade for classic Mags but technically how are they different?

the valves are different. on the old school RT the air enters the gun through the Body Rail, and up into the valve through what is called the Banjo bolt. the Air intake for the RT valve is on the bottom. On the Retro or RTP valve the air intake is on the side, like any other AutomaG.
Performance they are the same. just one will accept other valves (dont know why youd want to) and one cant... not to mention RT bodys are more expensive. RTs are out of production so if you buy new you will get an RTpro.
