Quad rail mounted front BUIS, and long term retention of zero

What are your experiences with retention of zero with DD Lite and Omega rails? How often to reconfirm and adjust for zero?

I have three ARs with the DD Lite rails, two with the 12.0 and one with the 10.0.

I use Troy BUIS, and ZERO them all at 50M, I have yet to have one lose ZERO.

Thanks.

I’ve had a Troy folder mounted on the end of a 12" Lite rail for a couple of years and if the zero has changed my “AMAZING” (not) markmanship skills have not show it. :slight_smile:
