Here, have a picture of a ткб-022 and wonder "where does the bolt go?"

i'm not really running anything but i haven't shot it since it got wacky. the safety hasn't had any issues. maybe i'm getting the names of parts mixed up but the pin that's holding the buffer and spring in place.
this right here.
that was gone when i went to take the BCG out. is there something i don't know about that would mess with the safety? i've replaced the pin since, but i'm not sure if i should keep that plate on that came from the carbine buffer tube between the fixed stock and the gun itself.

They've been talking a shit ton about anti drone defense- don't know if 5.45 will do much to a Predator sized big boy, even with AP, but against a Chinese quadcopter with a grenade slung on? Thy name is mulch, as long as you get within 500 yards.
Ok that's fucking cool, and not really surprising, stoner 63 in Vietnam anyone?Belt-fed AR in Ukraine:

The small drone proliferation just means that we are going back having a couple of guys in each plt on air watch, like we did in the 80s for helicopters. Those small drones are easy enough to hit with an LMG when spotted especially now that advanced sights are common.

You don't actually need the buffer retaining pin or it's spring.
Dis/Re Assembly is a little trickier without it but you can make do.
If it "fell out" it's most likely because the receiver extension (buffer tube) wasn't screwed in far enough.
Far as the rear plate goes, are you swapping out a collapsible stock for a fixed A2 style stock?
If so then no, you don't need the plate.
The plate has two jobs, it indexes the receiver extension and retains the detent and spring for the rear takedown pin.
The "face" of the A2 stock does both of these jobs.
If you're using a different type of fixed stock setup, like the Magpul carbine fixed stock, then you'll need to read the instructions or get help.
The safety is held in place by a detent/spring that is captured by the pistol grip so that should be fine unless you took that off too.

A LMG, especially belt fed, given a advanced optic, a longer barrel for just that much extra velocity, would rape drones. Things like those Switchblade bomb drones would have trouble at that point, to say nothing of quadcopters. Add in a portable radar for the squad to carry that would link with the sight to give range, distance, and direction, and you have a micro SPAGG.

Heck, some good old-fashioned birdshot would probably do the trick on those.
You can replace those easily. The first one I had I accidentally crushed.

Looks like all he needs is a proper pedestal mount, not a freely-rotating gimbal joint; something with adjustable T&E that can be locked for individual planes of movement.
The drones that would really worry me are those highly manuverable kamikaze FPV types, which would be a nightmare to hit with most anything, even a belt-fed LMG with optics. In that case I'd be reaching for a scattergun.
I dunno, for anti-drone pickets I'd probably want magnum turkey loads, or maybe #4 buck.

For anti-drone roles, best option is heavy goose loads with tungsten shot. Don't need big pellets, but need more of them.

No, I was mistaken. I confused the takedown detent spring with the safety detent spring.

the receiver extension plate is required by most carbine/collapsing stocks, but not by the A1 or A2 fixed stock the stock itself will interact with the lip on the rifle receiver extension to retain the rear takedown pin. the receiver extension plate serves two purposes on the carbine stock: it retains the rear takedown pin detent and spring; and it provides a shaped bearing surface to keep the stock at the correct position. there is a spacer for the A2 stock and the end of the receiver extension which is highly recommended for the upper butt plate screw but not technically required if you use loctite or something to hold the screw in place.
on the AR-15, the selector detent and spring is retained by the grip. the receiver extension plate should not interfere with the selector.
the recoil buffer retaining pin is under spring tension and the receiver extension is not uniform - there is a distinct lip that retains the buffer retaining pin in its position and this requires turning the receiver extension sufficiently to engage the pin, but not too much where it impedes its movement.
if your recoil buffer is not retained, it may be out of specification. the typical A2 recoil buffer has a rounded triangular shape, and it's common to rotate this so one "point" is downward, better contact with the retaining pin. technically this is incorrect the "point" should be at the 12 o'clock position so the flat does not chip at the retaining pins rounded surface, but it'll rotate a little bit anyway and often there's no real harm other than marks unless you have an over-gassed rifle or you shoot full-auto continuously (Shrike, et c) and never check the receiver extension.

you fellas really helped me figure out that stuff with the AR, thanks!

I personally hate the buffer retaining pins. Years ago all my AR's went captive buffer, I purchased a JP silent buffer and then went over the lathe and proceeded to make 2 more at home based on measurements from the I purchased. I absolutely love projects I get to use a lathe/mill, especially gunsmithing. When you have your own springs and weights you can custom tune for a heavy .300BLK load or a heavy 9mm load etc. Not to mention they do actually sound better, if you are running a can and subs you can hear the "sproaing" with the factory setup but captive it's nice an quiet. Full disclosure, I highly doubt it would have actual effect on DBs perceived or measured but, I'll just say it sounds better.

Yeah, I went a similar route.
Got one made by Armaspec and hope one day these things just become standard.

When building my first lower, the buffer retainer shot out across the garage. My buddy actually managed to find the pin, but the spring was lost. Protip: spring from a retractable ballpoint pen works in a pinch.

I always like the plastic bag trick, you get a big ziplock and put what you're working on in there, you can see and springs wont launch themselves across the room.

I fired my M16A4 clone for the first time today.
It was very laser accurate and felt the power come out smoothly lol.
On a side note, do I have to be worried if one of those trigger takedown pins start moving out to one side, and not being flush with the lower receiver.

if the take down pin detent is installed and has spring tension and the detent moves freely, then no. the detent will prevent it from walking out.

If we're taking a pedestal mount, assuming weight wasn't a issue, maybe this'd be on a truck, I'd have a semi auto mag fed shot gun, 12 gauge at least, if only for standardization, though 10 gauge would push it further, and something like a M249 or a belt fed AR-15. This way, you'd have access to both ways of shooting it down, close range, and if not, tungsten pellets from the shot gun that you can rapid fire until empty.
It's a fairly complex issue in the world of small arms, and countries are only starting to catch up. Poland has this 12.7mm WKL machine gun turret. Lots of ammo, high rate of fire being a minigun, and cheap to replace. (Though not as cheap as our SHTF anti drone setup)
