9.5" SMR on mid length setup w/ A2 FSB

AR/M4 AR Technical Discussion

I’d like to put together a mid length upper with a fixed A2 FSB and a Geissele MK13 SMR. Anyone know if the 9.5" length SMR will fit (unmodified) in conjunction with a fixed A2 front sight? I’m aware that the assembly would require the rail to go on first, then the front sight. I appreciate the insight.

PS: tried the search function to no avail but maybe I missed it out there.

Nine and three-eighths inches from the rail on the upper receiver to the FSB, so no. :slight_smile:

Thank you for your reply! Perhaps a trip to a cnc mill is in order.
