Hola, I am an investigator at a small agency. When I was a Patrol Officer I carried my AR-15 as soon as they authorized it. Now that I am mostly out of uniform I've been trying to set up a smaller, lighter active threat response kit. If it's light and all in one bag I'm more likely to take it with me and not be lazy (complacent). I had posted about setting up an AR-40 (pistol/SBR) to complement my duty G23, but this is currently cost prohibitive. My next thought was to make my Ruger PCC (.40) a little more tactically oriented but then I came across a PSA AR-15 pistol build kit. The price was spot on and, with ammunition manufacturers offering 5.56 specifically with the SBR and LE in mind (Hornady SBR TAP ammo) I'm now going this route. So my question is this: Is anyone else using either an AR pistol or SBR as their Patrol Rifle? If so, how are you setting it up and what ammo are you using?
