  1. Thanks for the vid!  My Ergo-Z is coming in the mail.  I used a hack-saw to cut the delta ring off and then some pliers to get the spring and c-clamp off of the barrel nut.  Now it's ready to go!  I have the AA piston also.  Finally moving to a free-float rail.

  2. @SKRIBBLE4ME Being that the flip-ups are designed as a backup sight your sight radius loss will equal a negligible loss of accuracy. We have done it with positive results.
