11+1 Spring in.
13+1 Spring out.
Bore size is .690 with wedgits.
It prevents most rollouts.
Also, there is a mod I came up with for the bolt seen in this thread: https://www.mcarterbrown.com/forums/d...tyle-guns.html
the current installed version is the last pic.
It has stopped all rollouts and has not affected velocity, consistency, or pump feel of the gun. I will post current pics of the bolt mod if requested. It really does work like a charm.
Also not looking for trades.
