The biggy is how does the sight hold true?
That Hakko Electropoint that I got for $75 at CDNN has been bounced around in the back of my truck foe 5 years and never lost its aim.
Sadly, they arent available anymore
My EOTec stays on. Plus, I have a BUIS behind it that’s slim and doesn’t interfere with the charging handle operation.
That big scope you have, does it get in the way of fast charging handle operation? And if it loses zero or goes down, then what? Take it off and reinstall the old carry handle sight?
