Not sure if there is any interest in this stuff, I certainly have no use for it any longer..... Perhaps someone is interested in revisiting the early days of PCP modding.
Please note this is not a set of parts that a novice can buy and just screw together a gun. If you've never built a custom gun on your own or you do not have an airgunsmith lined up to build you one with these parts, these are not something you want to buy.....
To the right person, $150 shipped to the lower 48 should be a bargain. Paypal F&F preferred.
A kit of sorts, to make a long barreled QB78. Due to tube length, at least a 25" barrel is required. You could always have the tube shortened/rethreaded, a simple job for a machinist.
36" long SS tube made by Don Cothran safe for 3k fills, Don even said up to 3500psi but I stayed at 3k....
Fill adapter, IIRC from a Disco.
Cothran Valve with longer stem for use in QB78
Consider the below parts as free to the buyer of those parts listed above. You may or may not find these suitable for your use.
QB78 breech previously used for a big bore. Modified with J slot to allow for bolt retraction and full bore porting. The bolt will push the projectile past the barrel port and retract info battery, leaving no probe in the airflow. Old bolt with .357 probe, IMO you should change the probe to fit your needs.
QB breech end cap, Crosman style tube cap, QB78 breech/trigger nut.
