It seems to me that it's at a slight angle where it's mounted. And that's why I think it's really only a rough guide.

  • Just a spirit level
  • The mounting doesn't seem ideal to me, it'll be very approximate

  • The spirit level works as it should. Fits perfectly on the CZ 457 ergo rail
  • Nothing so far.

Doesn't fit the rail very well, tried it on 3 air rifles, it'll need some tweaking :-).

  • The scale gives incorrect readings, and tilts to one side when tightened onto the dovetail.

When I bought it, I did not expect it not to be fitted nicely and tightly on the rail, or for it not to fit properly. The fault lies with the manufacturer, as it is too deep for the rail and does not hold firmly. It is sufficient for determining the rail level, but I do not like it for the money.

  • An interesting accessory for an 11 mm rail so I can see that the weapon is level when mounting the riflescope level.

A lot of music for not a lot of money. I have this level on all my windsocks (11mm and 22mm).

  • Handy thing to check the correct position of the gun.
  • The spirit level can be well controlled even when gluing.
  • The spirit level sticks out quite a bit to the side, but I don't see the problem.
