HE MAKES HIS TUBE-THREADS TO TIGHTER TOLERANCES THAN CROSMAN/BENJAMIN MAKES THEIRS. WE MAKE OUR ADAPTER THREADS OVERSIZED TO FIT CROSMAN/BENJAMIN TUBES TIGHTER FOR AN INCREASED SAFETY MARGIN. THIS IS WHY HIS TUBES ARE TOO TIGHT OF A FIT FOR OUR ADAPTERSThis listing is for one tank block with the o-ring and anchor screw, other parts and airguns are shown for reference only.To use this block, a PCP or bulk-fill valve is required, we have bulk-fill valves listed item# 115688339094. This is the short version of our Magnum Tank Adapter made of 7075-T6 aluminum. It fits tanks up to 2" OD. It threads directly into Crosman/Benjamin 7/8" OD tubes including 2240, 2240XL, 2250, 2260, 2300T, 2300S, 2300KT, 2400KT, Discovery, Challenger, Maximus, Fortitude, 1701P, 1720T, Marauder Pistol and many related models that share the same tubing and thread size. It's 1.854" from top to bottom compared to the long version at 2.986". It's 1.265" front to back, 3.225" overall length, .9645" wide and .9695" center to center for the tube and tank. The top of the block mounts about flush with the top of the tube. It fits standard paintball regulators, CO2 tank pin-valves and G1/2-14 adapters for 88-90 gram CO2 cartridges. The tank in the photos is 50.74 mm OD which is slightly smaller than 2", the 90 gram CO2 cartridge is 35 mm OD. There is only about a .7" gap between the barrel and a 51 mm (2") tank, with a 7/8 OD muzzle brake or shroud the gap is about .45". There is no black anodized version of this block for the time being, only the long version is available in black. To use this tank block on a 22XX model that operates on 12 gram CO2 cartridges you must install a bulk-fill valve or convert the factory valve with our bulk-fill valve-cap, custom valve screw for 22XX which requires drilling and tapping the valve to fit and the Discovery valve-stem we have listed to handle the higher pressure. That valve conversion, if done correctly, is safe for CO2 or an HPA tank regulated up to 1400 PSI. For higher pressures you need a PCP valve with three valve mounting screws, if done correctly that can handle up to 3300 PSI, the tank block is safe for that pressure if installed with the anchor-screw. You can either drill the anchor-screw hole in the tube as described in the next paragraph or install it with threadlocker instead. The anchor-screw is the safer method and is recommended if you plan to pressurize the tube to more than 1400 PSI. It will thread past the point where it's straight so you thread it all the way until it touches the tube, then back it off a partial turn until it's straight. With threadlocker you get it straight with the tube lying on it's side and leave it until the threadlocker sets. Only use a tiny bit of medium-strength threadlocker or you will never get the block out without damaging it and/or the tube. A heat-gun may be needed to remove the block after the threadlocker has set, only heat it enough to be able to turn the block, the less heat the better. Do not use a torch or any heating method hotter than a heat gun, the tube can lose it's structural integrity if heated too much, heat evenly around the diameter of the threaded area. MARKING THE ANCHOR-SCREW HOLE LOCATION: Thread the adapter all the way in, then back it out until it points straight down. Mark the center of the hole 1-1/64" from the back of the block, not the front of the tube. Deburr the inner edge of the hole after drilling so the o-ring on the adapter doesn't get damaged during installation. If using the harder 90D o-rings, which it comes with, you need to tap the front of the block lightly with a rubber mallet, block of wood or your hand to get it started into the tube without pushing it past the anchor-screw hole, then push the o-ring under the edge of the hole with a small slotted screwdriver to prevent it from being cut. The screw is T10 drive with a head diameter of .271". The hole should be .275" - .281" (9/32) to fit in a recessed fashion like PCP valve screws do. For regulated tanks, install the tank empty, then fill it. For CO2 tanks, use an on/off valve attached to the pin valve so you can install the tank, then turn it on. It's nearly impossible to install a tank with high pressure or CO2 in it, as soon as the block starts to open the pin-valve the threads lock-up tight before it's threaded in far enough to be safe.
