retro valve questions

[twofortyz]

I have some questions on the retro valve. I have heard that the automag rt has a reactive trigger. Is this true? Is the valve what causes this or does the rt have something special that causes this?
Thanks!

The retro valve is the same valve that is in the RT pro and is functionally identical to the valve in the older RT. It gives your mag a reactive trigger. It pushes your finger back with 2x the force it took to pull it. It allows you to fire the gun really fast, and it eliminates shootdown and cuts down on short-stroking.
