How hard would it have been for them to drill a hole through from side to side for a regular style takedown pin.
I mean, there's enough material in the piece that protrudes down from the upper for them to drill a hole in from the bottom for a 1/4" bolt. What made them think they couldn't drill a hole through sideways and do it right? Even if they had to make the correct length of takedown pin.
As a bonus, by replacing the bolt takedown system with a cross ways push/pull pin they could have actually made a magwell that wasn't angled up towards the front so much.
That stupid little bolt is the main downfall of the whole design.
