The kit will work on all Marq series guns including the Marq 6, Marq 7, Rapper, Closer, Darq Marq, Russian Legion and Edge.
Tired of running out of air during games?
Are you a back guy who loves the accuracy of the Marq but just can't get the shot count you need?
This is the solution!!
The new design will lower your LPR to 65-70 psi and your HPR to 190-200 psi.
Players are getting up to 1800 shots on a 68/4500 tank. That is a 600-700 shot improvement!
This bolt is the latest version with a "quick disconnect" for easy
maintenance. Not the first version that used Loc-Tite to secure the
bolt tip.
Detachable bolt tip comes with a pillow tip installed
Kit comes with replacement outer engine o-rings and allen screws to install your original back cap.
This is the best upgrade for the Bob Long Marq series guns you can buy.
