Thinking on and planning 308 build.
I'd like a functional upper and lower.  I like triangular hand guards and a military style gas block without the sight on it.
I expect I'll have to get a barrel and hand guards and gas block myself.
What's a good economy rifle to look for?

You should look into the problems we have had building those.  Most came out fine, if upper/lower were from the same maker.  There is no standard like we have with the 5.56 side, even though the fire control group is mostly universal.

There is a tacked thread with old info up top of this sub forum.  Probably some more builder guys will chime in, I’ve only put one together and even with a DPMS upper/lower it was a fight to get reliability.  All the ones I’ve bought as complete guns were much better.

Here is some old but relevant info.

I'm looking for an assembled rifle.
Something affordable, that I can change to the hand guards and gas block I want, if need be.
Something assembled, stainless barrel, 7.62 chambered with the lowered gas block, triangle handguard, no carry handle , no forward assist, and scope ready would be better.
I'm not into the free float stuff.

Budget, look at PSA.

Aero was a good choice but they’re dead in water at the moment.

Consider the gas block and whether it will have a suppressor.

Consider the gas system. I only do rifle length, nothing shorter
in large frame. Different creatures than the AR15, most definitely.

Budget friendly is PSA these days.

My bad, it sounded like you wanted to build.

PSA might be the way. They have plenty of choices for sure.

Shame dpms hasn’t come back in .308, mine were gtg.

I like this Ruger sfar.  I guess Ruger didn’t, I think they are discontinued?  If you wanted to try the small frame .308s
They are out there.  POF is one. Very similar to the sfar.  They shrunk the lower and BCG.

If you can find an old dpms they were pretty solid and shouldn’t be $.  They will be heavy.  I got 700$ for this one I sold recently.  It was a good one.

Also, I get the triangular hand guard thing, but they aren’t very popular.  Possibly some retro set might work .

The old DPMS guns were built well.  They are the "standard" in terms of parts compatibility and easily worked on and customized.

I regret not buying an extra one back then.

Ugh to the forward assist. Solid A2 stock, the triangle hand guards, flat top with rail.
Are there AR10s like that?

Anything’s possible with enough $.   You might not find one like that on the shelf.  F/A is pretty standard and triangular hand guards are not.

I understand.
I know what I want.  Unfortunately, other people don't want the same.
I end up having made, or making, what I want.
I miss my gun shop I had. It was set up in a small, antique mobile home.
It actually had built in turn signals, I believe one like it may have been on an "I love Lucy" episode.
I did barrel relining, ceramic coating, antique gun repair.
That's what I hope to have again some day, only not that particular trailer!
A mobile office, about 12x40 would be all I would need. If I ever fire up the hot tanks, I'd have a separate building like I used before.

I appreciate all the input here.
Someday I'll get it together and get what I want.

I’m a big fan of the S&W M&P-10. It has most of what you want. I’ve had one since 2013-2014ish. It’s been a reliable gun for me. I’ve beat the heck out of it in multi-gun matches.
