Robocop1051 Posted February 14, 2015 Report Share Posted February 14, 2015 Just measure the thickness of the rail, above the charging handle opening. 5/16" = low rail 3/8" = high rail Quote Link to comment Share on other sites More sharing options...

survivalshop Posted February 15, 2015 Report Share Posted February 15, 2015 Just measure the thickness of the rail, above the charging handle opening. 5/16" = low rail 3/8" = high rail I used to think it was that easy , but not so much any more , with all the different offerings now a days or what was made in the past . The reason I asked for caliber is we sometimes get requested info for the wrong platform , I'm just being careful . The Thread that has the measurements from the rail to the bottom of the Upper receiver are interesting & can be used also . 2.060" for the pre-2009 DPMS high rail height & 2.000" for the post -2009 low rail height . With the AR10 being a little lower ( 0.020 " I think ) than the High rail height of a DPMS . Confusing to some . <dontknow> Quote Link to comment Share on other sites More sharing options...
