With the Great Black Rifle Panic Buy of ‘09 over and prices plummeting everywhere I look, I’m starting to toy with the idea of surrendering my status as the only shooter in the country who doesn’t yet own an AR. It hasn’t helped, I’ll note, that Stingray did such a good job of explaining his own AR build, or that Tam had to go and show off her super-secret-squirrel (and very cool) quick-change-barrel upper.
So I started trying to make sense of barrel contours, twist rates, A1/A2/A3/A4/A^n uppers, T-marked uppers, F-marked front sights, M4 feed ramps, 2-position, 4-position, and 6-position stocks, CAR-length, mid-length, or rifle-length gas systems, .223 vs. 5.56 vs. Wylde chambers, agonized hand-wringing over the presence or absence of parkerizing under the front sight base, and all the other minutiae that AR fans obsess over.
…
That way lies analysis paralysis.
Basically, my current thinking would have me stick a Rock River Arms mid-length upper with a chrome-lined lightweight barrel on top of a Cav Arms complete lower. The goal being an ultra-light and very handy little gun, one that goes along with my idea of what an AR is for.
To me, the AR is more M1 Carbine than M1 Garand, but with better long-range potential due to the velocity and trajectory advantages of the 5.56 round. So there’s no reason why a recoilless little thing like that should weigh 9 lbs; I literally have an elephant gun that doesn’t quite hit the 8-lb mark on my scale. No, keep it light, keep it simple, and avoid covering 95% of the surface with rails you’re never going to use for anything other than self-inflicted hand lacerations.
The Cav lowers seem to enjoy a devoted following and offer a full pound of weight savings compared to a regular A2 lower assembly, which I really like. And Rock River also has a fine reputation as well as being the only apparent source of an off-the-shelf upper in the configuration I think I want.
I like the mid-length idea since it gives you a bit more sight radius, a little longer gas system, and a slightly better-looking end result. I should also admit that, while I’ll probably win the lottery before I ever need to use a mounted bayonet, it annoys my inner perfectionist that you can’t actually use the bayonet lug on a 16″ upper with an M4-length gas system. Yes, I’m fully aware of how silly that is. It still bugs me.
As for sighting, well, I dunno. I could probably get along just fine with a regular A2 upper, or a detachable carry handle on an A3. I’d rather not drop $900+ on an ACOG. EOTechs are certainly nifty, but they’re also spendy and heavy. I’d probably get an A3 with the handle, in case I change my mind down the road.
But I’ve shot an AR exactly twice in my life and readily admit my lack of expertise regarding the platform. So am I completely full of shit, or does my thinking make a little sense?
