Does not fit lmt mars l lower - Geissele Ultra Precision 5 Axis Trigger Guard

Bought this planning on installing this in my LMT MARS L lower. Does not fit. Would have to file on the 2 rear tabs to get the trigger guard to actually rotate up into place…. So although it’s a nice, solid quality piece, I can’t use it for what I intended. A cheap polymer MAGPUL guard worked no issues…..Guess that’s 30 bucks tossed into the bulk parts bin or a gift to a friend.
