Why would you think building on a DPMS receiver would be any different than building on any other lower?
DPMS is a great brand and a few people here have spit on them because of a bad LPK or bolt carrier......
Listen DPMS makes MIL-SPEC parts that either meets mil-spec quality or exceeds it.
I use all DPMS parts in all of my builds because I expect quality, dont expect 100% quality
with DPMS or any other brand for that matter. All parts are made by the thousands if not hundreds
of thousands............millions if you really want a answer. People give them a bad name because
they got one of those few parts that had a flaw, too damn lazy to return it and get a new one.
I've seen more Bushies and Colt go back and forth to the factory because they dont run.
Keep DPMS in high regards, because they hold you in even higher standards.
