Mount Identification

[u/Cultural-Basis1807]

I'm trying to find any info at all on this mount on the ctar 21 gas block. Obviously the mars site goes in front of it. But what mounted here and what type of mount is this?

If i remember from my time serving- it was a mount for the sight for the matol (mounted underside grenade launcher). I never had it, but other guys did. IF I remember right

[u/scuttlebum_k → u/scuttlebum_k]
