Now painted in black, it did not look that bulky to me...
It reminds me of the barrel and the tip of some sniper rifles, like the
or the M107
or Steyr 50 HS
May be some holes in the side of the box, will make it look more technicalů
(of course does not work so good with a Heating System)
Did you shoot it over the Chrony? I would be very interested to know what speed you can get with strong bands.
Nice work, I like it very much!
