Midwest industries rail flex
So I installed a Midwest industries keymod 15" rail gen 1 a while back. I had to remove the rail yesterday, I re-installed per instructions, and my front sight had to be adjusted almost all the way down to get poi-poa at 25yds...I thought that maybe I had somehow missed something when I installed the rail.
Upon inspection tonight after another tear down, I can move the rail in any direction by simply putting pressure on it or hitting it on my knee with mild force, and it stays in that poison. I know all rails/barrels have some flex, but they usually bounce back. This does not!
Any ideas? At this point I think my best option is to go a different route with the rail. If my irons won't stay zeroed after my knee bumping the rail it is really of no use to me.
Thank you in advance for your help.
