3delta Posted October 18, 2014 Report Share Posted October 18, 2014 After firing the last round in a mag the bolt won't stay open. After removing the mag and manually attempting to lock the bolt back the bolt slides over the latch. The latch is free and not binding and appears to be operating fully. With the mag inserted I can pull the bolt to the rear and the Magpul magazine will then hold the bolt back. The rifle is a DPMS complete upper and was assembled at the factory. The lower is an 80% lower and the lower parts kit is DPMS. The pin to hold the bolt catch is threaded and as stated appears to be fully functional. Any suggestions will be appreciated.
