Robocop1051 Posted February 14, 2015 Report Posted February 14, 2015 Just measure the thickness of the rail, above the charging handle opening. 5/16" = low rail 3/8" = high rail
survivalshop Posted February 15, 2015 Report 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>
