Took the new rifle over to the range today. Scott scrounged up a replacement for the pin I lost, checked over the installation of the other stuff, and torqued everything to spec. He also had a bore laser we could use to make sure the sights were zeroed once we installed them. The selector lever detent problem was a new one on him as well, but he was able to persuade it to come out, and when reassembled it... worked normally. Neither of us has any idea why it didn't just work the first time. Maybe a burr somewhere in there that got knocked off when he put it back together? No idea.Once those finishing touches were taken care of, I repaired to the range and did a little test firing. It went pretty much perfectly! I only had 20 rounds of ammunition, so I started with a magazine loaded with only two, the theory being, if something was wrong with the fire control group and it ran away, I'd only get a double tap instead of a 20-round bullet hose, but if some less catastrophic feed or fire problem happened, I'd just get one shot and not the second one. Either would be useful diagnostic information.
In the event, I needn't have worried. The only problem I had in those 20 rounds was a failure to feed the first round after reloading, which a quick bolt cycling cleared up immediately. Besides that, the new rifle ran like a champ.
So hey, uh... ! I had a little help, but mostly, I built a rifle! And here it is!
This is the lower receiver as it appeared in its original packaging. This part is the bit that is, legally speaking, the firearm, and so has to be purchased from a licensed dealer on a standard Form 4473. Everything else can be bought over the counter or by mail, if you live in a state that allows the latter (which I do... so far).

I note that Ruger has moved; they were headquartered in Southport, Connecticut for many decades (although I thought they had moved to Arizona sometime in the '90s; maybe they just have a manufacturing plant there or something).
So yeah. The peculiarities of the AR-15's design are such that this thing is "the gun" by the ATF's lights. Everything else is accessories. So I bought some.


I considered going fully retro on this build, but ultimately decided to go with some relatively modern bits for reasons mostly of cost and availability. I'll spare you the nerding out about the specific brands of the bits, apart from noting that once again I have acquired a Hogue Monogrip instead of the hard plastic one that came with the lower receiver parts kit, because Hogue Monogrips are the bomb. (Unsolicited plug.)
I still think flattop ARs look weird. Some outfits actually make M16/M4-style carry handles that attach to Picatinny rail; I might get one just for appearances. Although if I do that I'll have to redo the sights...
The other major departure from the "classic" AR profile, apart from the accessorizable handguard, is the lack of the usual combination gas block and tall front sight assembly. Again, this was mostly a matter of cost; those assemblies cost more than a low-profile gas block that fits inside one of those rail-top handguards. They're also kind of a pain in the ass to install, not that all the other fiddly bits on this thing weren't. :)
You want to know the bit that I had the hardest time with? Apart from the pin that disappeared on me? The dust cover. That little aluminum flap was such a hassle. You've got a pin, and a spring, and the spring has to be in there a certain way and preloaded with a ¾ turn while you're putting the pin through, and... yeah. There are harder tasks involved in building one of these things, but I didn't find any that were more annoying.
If it doesn't look like the rifle has any sights in those photos, it's because they're folded down. This is what it looks like when they're up.

The sights I used are really intended to be backups in case your optic gets broken, which is why they fold down like that, but I can't afford a decent optic right now, so for the moment they're it. They seem to work well enough, once I figured out that you have to put the center post in the aperture and not one of the protective wings. Eyeroll. (I have this trouble with Lee-Enfields too...)
So, anyway. A project I decided to undertake more or less on the spur of the moment. A little present to myself for surviving The Bureaucracy.
Here's a fun thing about the AR platform: once you have the lower assembly, you can build multiple uppers for it. They swap out with two pins. So if I felt like having, say, a pistol-caliber carbine, I wouldn't need to put together another lower, and legally they'd be the same firearm. That would be an extravagance for another time, though.
