Hello,

I am looking for a handguard rail to mount optics on. I want something solid that will hold zero. What are your experiences with those?

This one looks quite solid, but I cannot find any info about it.

It looks like this version was adopted by the Slovak Army. Apparently they were made by some Canadian company.

I believe that Czechs adopted B&T type and Zahal Alpha.
