I went through Paris Island, SC. in the heat of summer this year. We were issued M16-A4s during week 1. Day 1, I believe. Mine was an FN as were most of the others. There were a handful of Colts. For the next 13 weeks, we would spend every waking hour with our rifles which were OUR rifles and no one else's. It was stressed that we were never to surrender our weapons to anyone for any reason. We wore A2 style carry handles until qual week when we re-visited the armorer for ACOGs which we would retain for the duration which included a couple thousand rounds fired between practice, pre-qual and qual, as well as the live-fire exercises on the crucible. All of our rifles took multiple sand baths on the mock-beaches we stormed, and muck I wish I could forget trudging through the swamps on the combat endurance course got all over the internals. The optic was submerged repeatedly... and still worked flawlessly the day I turned in my M16-A4, the serial number of which I will remember for the rest of my natural existence. 10562814. Hah... I spoke to some smaller females at my schoolhouse who were issued M4s. They were all Colt and wore a different Trijicon optic. For as well-used and poorly treated as the rifles we were issued were, they still shot remarkably well. I was top-shot in boot camp, which is something I'm most proud of.

all in a A1 of course! Appreciate you taking the time to pass that on. Good luck and Godspeed in your time in the Corps.
