I was ready to buy a few after work yesterday, and they were sold out when I got home. Glad they showed up again, just picked 10 up. I have a QC10 glock lower, and Rainier just got the Colt lowers back in stock, so time to try that. One major reason for me to switch is the ability to add an ambi mag release to the colt lower, which will make PCC mag changes (especially on classifiers where they are occasionally mandatory) a bit faster for me as a lefty.
