Had a generous member give me four 13rd G21 mags with +2 extensions almost a year ago as I prepared for this build. They just sat around until earlier this week when I tried them in the lower. None of them would lock the bolt open, but the one empty factory mag I had handy would.
Ordered some extra power springs a couple days ago and got them today. Swapped them all out and now all mags appear to be activating the LRBHO feature of the QC10 lower.
