paired with an aero lower and the takedown pins slid through both halves with thumb pressure. no slop, no rock. forward assist hole indexes correctly. exactly what you want at this price
standard M4E1, mated to an aero M4E1 lower without play. forward assist hole was correct, dust cover hole was correct. no machining burrs in the carrier raceway. as advertised for the price
