MIL-SPEC NOT. Be afraid...be very afraid. BCG's out of spec, Charging handle out of spec...Upper-Lower out of spec.\r
When closing the upper onto the lower... the detent pin holding back the buffer/sping doesn't collapse and gouges the buffer. Several trips back won't issue replacement..\r
Haven't fired 1 round yet..brand new.. I'm screwed\r
\r
Stay away!
