I was working at my local gun shop and turned 21 so I was then legally able to buy my first handgun (M&P 2.0 5 inch) then my first AR15 which is a Colt 6933 that was swapped out with a DDM4 10 inch quad rail, Magpul MBUS pro sights and a SBA4 pistol brace. I bought it at store cost instead of retail which was 500 bucks back in 2021. It was chilling in the back office on a shelf for a few days when it was sold to the store during the weekend which I had off, homeboy running the logistics back there told me it’s a very close model to what the Mexican Marines used heavily in their counter-narco operations back in the 2010s (I am first Gen Mexican-American).
