Great little unit
Found this scope level to be very, very good and very simple to use. It appears to fit the rifles I have and on one particular older rifle (1918 action), it worked a treat. Previously on this rifle, it has been extremely difficult to get the scope in the correct position due to rounded surfaces and lack of room for levels on the flat surfaces.
This little unit slips inside the breach so easily and is held quite firmly with the magnetic base.
The other bubble sits on top of the turret but can dislodge fairly easily if you move or bump the rifle, mainly as it is so light.
Care needs to be taken with this bubble though, to ensure you have it exactly at right angles to the scope as, if on an angle, can give an incorrect indication of level.
After the scope was mounted, I check the vertical alignment using a rope suspended from a tree branch and found that everything was exactly where it should be.
To me, it is very well priced for what it is, but for what it does, is pretty cheap.
I would thoroughly recommend this unit to anyone who has cause to mount their own rifle scopes.
