Alright, drop some knowledge on me then.
What has happened so many times thus far that MPI is a critical factor of quality control in any way. There must be gads of evidence
based on your arrogance.
Likewise about the gas key. There must be massive accounts of bolt carrier failure on any "sub par" AR15's. Where do I find all the information you base your opinions on?
Educate me.
i seem to recall Magpul making a insert for their grips to hold a spare bolt in case the one you are using breaks.
either they designed this specifically for NEA or there are a lot of other reported bolts breaking... and basing your product on such a small target market is not good business.
funny... this Magpul product was released before NEA started making rifles...
