CLICK ON THE ARROW BELOW TO VIEW DESCRIPTIONS OF ALL THE TUBES IN THIS LISTING

All of these are Crosman/Benjamin Sheridan tubes that have been modified and reworked to fit and perform perfectly. A lot of work goes into each tube, they very time-consuming to produce. Some have slight scratches and marks from machining and handling but nothing significant, all of them look nice.

 

 15.5" DISCOVERY TUBE 

 This tube is shortened with the original front threads and custom-machined holes and slots. The second photo shows the back-end of this tube. It fits the custom valve screws for discovery I have listed. It's honed so the inside's smooth as glass for a perfect seal and smooth hammer function. It has no caliber markings, it works with either caliber. The gauge hole is smaller, similar to the 1701P and Marauder Pistol, so it's stable to mount the gauge with or without an extension (gauge port adapter) and with or without a forearm or stock. It's intended for custom PCP carbine and pistol builds. It will fit Discovery, Maximus, 2250, 2400KT, 2260 and similar models. The Maximus valve will not fit this tube. Discovery-compatible valves like the Magnum Valve I have listed will fit. If also using my custom valve screws for Discovery this tube will handle 3000 PSI safely.  These have a laser-engraved serial number that may be on the side, top or bottom of the tube. There may be some light scratches from handling during the machining process.  Both inner breech-screw holes (center position) are threaded for use with Discovery, Crosman Custom Shop and standard Crosman steel breeches. My Magnum Valves will fit with either inner breech-screw location. A Discovery valve will block the hole the standard breeches use.

 

 2240 PCP TUBE 

 This is a standard 2240 tube with side valve-screw holes added. It fits the custom PCP pistol valve screws I have listed. It's honed so the inside is smooth as glass for a perfect seal and smooth hammer function. The hammer pin slot is deburred and lightly polished for smoother cocking and improved hammer performance. The outside of the tube is lightly brushed (with a very fine oiled brush) to soften sharp edges, bring out more detail in lettering and give the tube an overall more finished look and feel. This tube is safe for up to 3000 PSI when three of my custom valve screws are correctly installed. I suggest using one of the custom fill adapters I have listed with a pressure gauge and 5K burst disk to increase the safety margin. A small section of the stamped lettering is on the pressurized part of the tube. In spite of rampant paranoia this doesn't create a safety issue, the tubes failure point is still over 9000 PSI. The 2250 and 2260MB tubes do not have stamped lettering on pressurized sections of the tube, the 2260MB requires the longer bypass valve-cap I have listed to clear the lettering.  


 

 2250 PCP TUBE 

 This is a standard 2250 tube with side valve-screw holes added. It fits the custom PCP pistol valve screws I have listed. It's honed so the inside is smooth as glass for a perfect seal and smooth hammer function. The hammer pin slot is deburred and lightly polished for smoother cocking and improved hammer performance. The outside of the tube is lightly brushed (with a very fine oiled brush) to soften sharp edges, bring out more detail in lettering and give the tube an overall more finished look and feel. This tube is safe for up to 3000 PSI when three of my custom valve screws are correctly installed. I suggest using one of the custom fill adapters I have listed with a pressure gauge and 5K burst disk to increase the safety margin. The 2250 tubes do not have stamped lettering on pressurized sections of the tube.


 

 2260 PCP TUBE 

 This is a standard 2260 MB tube, that's the Sheridan version as shown in the last two photo's, with side valve-screw holes added. It fits the custom PCP pistol valve screws I have listed. It's honed so the inside is smooth as glass for a perfect seal and smooth hammer function. The hammer pin slot is deburred and lightly polished for smoother cocking and improved hammer performance. The outside of the tube is lightly brushed (with a very fine oiled brush) to soften sharp edges, bring out more detail in lettering and give the tube an overall more finished look and feel. This tube is safe for up to 3000 PSI when three of my custom valve screws are correctly installed. I suggest using one of the custom fill adapters I have listed with a pressure gauge and 5K burst disk to increase the safety margin. The 2260MB tubes do not have stamped lettering on pressurized sections of the tube if you use the longer bypass valve-cap I have listed. Standard 2260 tubes have longer sections of stamped lettering that extend over the pressurized section even with the bypass cap. This tube has the Sheridan name lasered on the right side with the serial number several inches in front of it, the stamped lettering is on the opposite side (left) from a standard 2260 tube. These were removed from new rifles, Crosman doesn't sell this specific version separately.
