This past week my new sights arrived.
My initial impression of everything was good, it wasn’t until I actually mounted them is when I noticed a problem.
When I mount the sight directly to the receiver it mounts ok and doesn’t move, but when I mount it to the Centra Block8 it is loose, even with the mount on the sight tighten all the way down.
Already contacted the store, need to send them the Block8 back hope to get this fixed fast. So I haven’t been able to test the sights as of yet.
