Note from Simon:  I just installed a set of QUICK PINS and the SAFE MAG along with the FLOP STOP on one of my AR15's.  Simple and quick installation-took 15 mins.  Took it to the range-very impressed with  the quality and operation.  Mag changes in 3-4 seconds-sure I will get faster with practice. A+++ for our friends at Cross Armory
