I did a search but couldn't find anyone talking about using an ambidextrous mag release on the M&P 15-22. Anyone try one of the few that seem to be available? They all seem to rock over the body of the upper receiver to pull the mag catch out, but I was wondering if the polymer would hold up to that kind of force repeatedly. Also, I've seen that there are aftermarket mag release buttons available, but are the rest of the components standard? If the body of the upper is wider than a standard AR-15, would a standard mag catch even work?
