Abolo Master Tactical AR15 45 Degree Offset Front and Rear Rapid Transition BUIS Iron Sight

screw stripped on install, mount will not stay on rifle. ill be replacing with an all metal one soon and thats all i will use.

These have held zero for me over the course of 3 trips to the shooting range, for a total of around 250-300rnds. I'm not sure what more you could ask of BIUS. The rear sight is solid with very little play.

Nice and light weight and very durable. Takes a little getting used to but becomes very easy to zero in on target

It works and it’s affordable.

All was good just wish it was all metal
