How wet should I run the bolt during break-in? Should I do the same after 500+ rounds??
I just got my Spike's 9mm upper, mag block, buffer and mags delivered to me. I plan to run it this weekend. I'll try factory 9mm ammo first, then switch to my reloads after it runs reliably on factory stuff.
I'll test the Spike's mags and then the Metalform mags.
