    With Jeorg’s interest in crossbows and participation in the design and marketing of some, it might be time for a crossbow-specific subforum here. Especially since the other crossbow sites around the web seem more ‘respecting’ of the endless search for 600fps than of the items Jeorg (and apparently many of us here) find enjoyable.

    Here’s my Steambow Stinger, with the shoulder stock I made for a previous Cobra

    And here’s the final shoulder stock. This is nothing more than PVC that was heated in water and shaped. Took a couple tries to find the right shape. The ‘hump’ on this functions as a cheek rest if you are using the ‘iron’ sights. There is no cut to help insert the ball end; the tube was simply heated enough to allow the ball end to be shoved in. I then clamped the sides around the end after it was in position so it is locked-in. Flat black spray paint was applied to finish it.

    Btw, the stock secured in place helps apply leverage for cocking with the additional prod insert.

    Added a pressure switch for the laser. The cable is routed under the plastic furniture to the pistol grip. So now it’s only ‘lit’ when you’re ready to shoot. This is both more stealthy, and more healthy (since you can’t forget that it’s on, and thereby accidentally get the laser in someone’s eye).

    Oh, and an informational followup. The Stinger is apparently, in German/Austrian law, a ‘toy’. This is in part because the provided laser is not precise in windage & elevation adjustability. How do we make it precise in one aspect, and thereby precise in the other?
    Note that the below all works best if you’ve already followed the included instructions, and gotten it somewhat close to where it needs to be.

    Windage can be accurately adjusted from 90 or 270 degrees, and elevation from zero or 90.
    The supplied laser has three equally spaced adjustment screws, 120 degrees apart.
    So all we need do is align one of the laser’s adjustment screws with 90, 180, 270, or zero degrees.

    To accomplish this, loosen the two mounting screws that hold the laser unit in the Stinger housing. Then turn the laser counterclockwise. This will loosen it from its switch (and luckily, that switch will retain an overall correct position for the laser). Turn it only until one of its adjustment screws aligns with true vertical (0, 180) or true horizontal (90, 270). Note that you will not have to turn it more than 1/12 of a turn to accomplish this. So your battery will remain correctly connected. Once any adjustment screw is vertical or horizontal, tighten the mounting screws.

    Now then. If your alighted adjustment screw is vertical, you’ll want to sight in elevation first. Once you get there, that screw is done. From there, the other two screws control windage.

    Likewise, if your aligned adjustment screw is horizontal, you’ll want to sight in your windage first. The other two screws then become your elevation controls.

    Just one more pic, against a white background (used a white towel, then some editing to make the towel disappear). It is now complete with the tactical flashlight.

    My Cobra RX Adder just arrived. Awesome.

    Both the Stinger and Adder are being modified.
    Stinger will be getting an extended picatinny rail for the handle so I can mount the flashlight offset there rather than up top. It looks cool up there, but I do NOT wanting to be reaching through that area - it’s dangerous.

    I’ve removed the ‘stock’ stock from the Adder, and made my own PVC stock. Reduces the weight of the crossbow by almost a pound.
    I’m going to replace the red dot with a laser, and then look into making a folding shoulder stock

    The laser sight arrived. Aluminum construction, solid, remote pressure switch. I mounted it in front of the red dot; all sighting devices should be up top. I will eventually make a cable arrangement that is invisible from outside the unit, but for now the coil works fine. No issues cocking the weapon.

    Only thing left to do is the folding stock, and so far it’s coming along. Oh, and the modification of arrows. Turns out the points sometimes come out of the practice arrows, which means I can cut them to length and get inserts and add broadheads. But that’s a couple weeks down the road. For now, the project is the folding stock.

    Do you think 175 or 150 lbs Bow of the Jaguar Crossbow would fit the adder?

    Interesting! Perhaps with a custom mount it could.

    However, I doubt there would be any power/speed gain as you are losing some length from the powerstroke. Unless you mount the bow out front of everything else. But then perhaps the cocking arm would not handle the strain....??

    But if you have one and you’re willing to experiment, go right ahead. But if I were you I would not experiment on an Adder; I would get a base R9 and experiment with that.

    My arrow creation for Adder. Top is the R9 arrow, bottom is the Adder arrow.... center is mine.

    Modified Titanium X mechanical broadhead on an R9 arrow. The front ‘tabs’ that push the blades open on impact have been removed. Reason is this is not a high-power hunting xbow; a 220 grain arrow at 260 feet per second might lose the needed penetration. In range tests, my arrow has great penetration while still having a 1-inch cutting diameter.

    I’m thinking about making a new arrow follower. Done correctly, this unit can properly feed six arrows without interfering with the sight line of your sighting system.

    Very cool, where did you get your tip for your arrow?

    It’s a TitaniumX two-blade that I modified. But I’ve tested it, and that modification is a bit too much; for ‘tactical’ scenarios, it’s better to not have as much penetration, and a bit of blade deployment. So the modification should be about half-way in cutting the front blade pushers.
