I was a bolt gun guy for decades, never ran an AR in the service, The Corps issued me an M-14 and it ran like a Raped Ape, fast and with a single mindset. I knew that if I maintained it, it would NEVER let me down...; and it never did. There was enough combat in the mix to confirm that assessment of mine, arriving home unscratched. I bought an M1A, loved it, sold it for emergency cash, then found out that I couldn't afford to replace it. I still managed to live on.
I did a bunch of reading and talking about the AR's. Back then, there were the Mil-Spec providers, and some Custom builders; good but, again, I couldn't afford a good one.
I found a Stag (in a gun store) and it had a 24" barrel on an AR-15. There always seemed to be one or more of that model standing tall behind the owner's desk, waiting for pickup. I asked him why and he showed me a target; from his own one of them. Order placed that evening (there was one brief phone all involved....). Eventually, I ended up with an identical pair (semi modified, both precisely the same. I had them for impromptu matches; and I could grab up either one with the same confidence. They worked, period. But they were not cheap.
I wanted to do other things (barrel lengths, chamberings, very lightweight, or bull barrels). That would have to be custom, and custom wasn't on my budget. But builder tools and parts were. I would start with an AR Stoner Upper (properly barreled) and a PSA Lower (bottom dollar model), buy furniture (nearly always Luth AR, nothing OEM fits me) and add an inexpensive two-stage trigger. Nothing to write home about but they all fit me absolutely identically, and operated the same.
For optics, they all wear Bushnell AR-XXX BDC scopes, which makes ranging a matter of using the LRF, and choosing an aiming dot on the reticle; fast on the target, smooth on the trigger. They are miles short of a special order gun from a professional builder, but I can afford them, and they can be (some have been) load developed to be adequately accurate for my moderate needs. I'll live with 1.5MOA, I want 0.5MOA.
Can I trust my life to them? I don't know, but I have above average hopes, and will probably find out the exact answer to that question, right soon, now. I live 50 miles from the Border and I hear it's likely to get rowdy around here, maybe even as soon as next month. Not looking for a row, but maybe making ready if one descends on me. Just like each and every one of my neighbors, Liberal or Conservative.
This week I also picked up the second 500pc jug of Top Brass 308 (there is a PA-10, same ergonomic configuration as the ar-15's), and three pounds of powder. I know the brass is all Mil-Surp so-so. But it's all mil-spec (i.e., same spec), and I have all the tools for proper prep. A couple of random handfuls of cases from both jugs all fit the case gauge and do not have inner grooves, so at least I have a place to start. All brass will be properly inspected and prepped as part of due course. I have near enough bullets, and near enough primers; and the Moon is still new.
