    Umarex HDS68 Paintball Shotguns

    I have 13 Umarex HDS68 shotguns for sale. 5 have had the valve block modified to increase the velocity of the marker. 7 have not been modified. All will come with the quick pierce cap required for operation, but not shown in the pics.
    $85 each shipped CONUS Group deals will be considered.

    The stuff I shouldn't have to say but must:
    I am not a dealer, broker or any sort of business. I'm a habitual Tinkerer. I love to restore/repair mechanical markers and return them to good use. These are excess in my collection. These are used/ refurbished markers. I have fixed any springs or Oring issues. Replaced broken or missing parts. I cannot give an unlimited warranty on any used product. If you have an issue with a marker I sell you, I will do my best to fix the problem. If you disassemble the marker before contacting me, I will advise on repair, possibly help with minor parts, but will not assume any responsibility for the issue. The valve mod is the procedure that The Inflicted posted on Youtube.

    A few things to know about these markers before you purchase:
    1. CO2 capsule is installed nozzle facing out. Pierce mechanism is in the cap.
    2. Only install the quick pierce cap hand tight. NEVER use the Allen wrench to tighten. This will break the bond holding the CO2 pressure chamber, causing leaking or blow off. Activate by tapping the bottom of the pierce cap.
    3. NEVER try to unscrew the cap under pressure. Same as installation, bad things happen. Push the pressure relief/pressurized pin first. This pin pops up when the marker is pressurized.
    4. This marker is currently set up for 12gram use. Velocity will decrease with the number and speed of shots. There is a constant air adaptor that will allow HPA or bulk CO2 use. Meaning you can get better shot consistency.
    5. This marker has the option to fire one barrel at a time or both at the same time. Understand that you have the same amount of gas used for each of those 2 choices. That means if the mod is set for single barrel 265 to 280 fps, firing both at the same time will be in the 200 to 220 range. If you set the mod to fire both barrels at 265 to 280 fps, then the single barrel option will be above 300 fps. Factory setting (unmodified) is low 220s single barrel and below 200 double barrel. I have set the mod for single barrel use.

      It's also a good idea to throw an Allen key in your pocket if you have to change 12grams in game. Can be hard with greasy paint hands. Good luck with the sale!

        I agree that the cap can be difficult with slippery hands. Personally, I use 3d printed knobs on the cap for this reason. I can add them to the sale if someone would like them. I cannot stress enough the risk of breaking the pressure cylinder bond from overtightening or removal under pressure. This is why I warn against using the Allen wrench.

        PS. Depress the red pin that goes up after being pressurized to release pressure before trying to remove. You can just hold it down with your finger

        Degassing and depressing the relief pin is noted in the description above. The knob is for people like me with grip issues.

      Araphel made me a cap for mine that helped with grips significantly, but I have found if you are diligent with the pressure relief cap it's not too bad.

        I have several MCBers make caps for all of my Umarex markers. Mostly for the ease of use, but also because I have nerve damage in both arms and hands giving me the dexterity of a Muppet.

        After I have my wife, and Secret Santa covered, I will take one of these modded. But I think it'll be after Christmas if you still have em.

          I'm sure I'll have at least one for you.

        Update on the HDS68s. I have checked and tested the entire fleet. There are 9 remaining. 2 have no valve blocks and will shoot single barrel 300 to 320s first couple of shots. The other 7 have been modified and shoot in the 260s. They can be tuned up a little higher but may shoot hot in warmer weather. I will test every marker before I ship.
