Really wanted to like these - LWRCI Skirmish Back Up Iron Sights Set

These would be great sights if they fit. Nice build, good quality, I like the look and function of them. The problem is mounting them on a rail. Other sights use a two-part system to mount the sights on a rail and will work on any rail, even if the rail is out of tolerance. With these sights, the mounting system is one piece, with the screw compressing the sight onto the rail. If you rail is out of tolerance, you either end of with the sights that wiggle on the rail because the rail is too narrow, or the sights will not slide onto the rail without using a hammer because the rail is too wide. Ended up returning these since they were basically useless due to this mounting system.

LWRC: remake these sights using a two-part mounting system and I will buy these again.
