TDP spec, non-ambidextrous magazine catch, fits AR15/M16. When used in conjunction with a large frame AR (AR10, LR308, etc.), a taller profile magazine release button is suggested, such as our
EMR-C, as the TDP spec magazine catch's shaft is made for AR15/M16 spec receiver width, a TDP spec magazine button will seat low, close to being flush to the receiver.
