Ahhh...my first gun...
I still love this one.
Don't think I'll every get rid of it.
The modified bolt is a stock unit with the venturi removed (ala needle nose pliers).
It also has a greatly widened valve port and polished interior.
I'd venture to say that it flows at least as good (if not better) than the AKA Lightning Bolt.
The ported & polished valve is just that!
I polished (to a mirror finish) the interior of the stock valve.
Plus I significantly widened and polished the opening to the bolt.
Also, there have been other modifications to lower operating pressure.
Currently I have the gun running at 210psi @ 240fps using small-bore paint (.685") in a Lapco AutoSpirit.
