[ARCHIVED THREAD] - Mute point

Posted: 12/31/2013 10:55:30 AM EDT

I know this model of rail has one alignment tab on the top part of the rail. Curious to know if anyone has used this rail in conjunction with a DPMS Lo-Pro upper? The DPMS upper is a little beefier than the standard A3. Prefer not to remove the tab if at all possible.

TIA
