I'm appalled by this question, if it was a serious one. Ranger, is this how poor your world view is?

After reading how I typed it, I feel ashamed :oops:

It was meant to be a simple question about why he is speaking english (very good english) in germany. It was not meant to be mean or have "poor world views"

I will go back and edit :oops:

Edit: is that better? :oops:

Now that you phrased it better it doesn't sound so bad :)

Have done it - I converted an old rifle stock for the slingshot crossbow, and I also attached a scope.

I strengthened the barrel by adding to more "rails", as the 3 stripes of Thera Gold per side bent the single steel tube slightly upwards. Now everything is OK!

Used a training band to adjust the scope and to test the accuracy - 10 meters, it shoots hole in hole in hole.

It is really long for a crossbow, but I love it!

Will do a video tomorrow, already prepared the ballistic gelatin...

Thats awesome, can you take a close up picture of the trigger mech, I dont get how it works

Here's what he told me :)
The trigger is just a lever that holds the roller parts together, like a fork. You pull the trigger and the fork lowers, releasing the rollers. Those swing out, because of the pull of the rubber, and the shot falls.

Ahh it was on youtube, I asked him the same question. I want to see a more detailed picture too, anyway.

Yes, I made the scope mount. Wasn't very easy, the nature of the gun called for just one attachment point, behind the lock. So I had to use thick steel.

Also, the clamps on the Bushnell scope do not have a wide "range", the rail had to be very precise.

I had to rebuild the trigger lever in order to make it fitting into the stock.

The 3 tubes makes it look like a triple barrel shotgun with square projectiles.

Well the walls of the tubes are just 1mm... a little bit on the thin side for a firearm! But for a sling-crossbow it is allright.

Video is uploading, tested it against gelatin and compared it with "real" ball shooting crossbows. They don't stand a chance.

BTW, I measured the draw weight. It is about 55 lbs for the strongest band set.

Thanks for that important information.

I believe that 75 - 100 pound draw is possible.

250 meter golf ball?
