TRACT Bubble Level for 30mm Rifle Scopes

It does the job intended. I put this on a Vortex Viper and it fit great. Tract is a new company that makes amazing quality optics so it makes sense this level works well. Make sure you put it on before you mount your scope. It will not slide between the rail and scope bottom when its apart. It has two screws and has to go together a certain way . Make sure the threads are on the correct side you want your bubble to be on. A One screw design on top would be better for ease of mounting . Price is outstanding.

I received promptly and as described, recommended.

Bubble fell out with first use at the range. The rifle was never bumped or hit against.anything. basically the glass bubble was no secured during manufacture.poor
