Ultralight Ultralight Rifles

We need a thread for sure.
It's pretty easy to use the info in this thread and transfer it to a gasser with a few minor changes.

I rarely shoot this, but the bare rifle is 3# 10oz and I built it before I built an UL-UL. It has killed a big black bear and a few deer. Has a Faxon pencil barrel. Could easily get into UL-UL range with developments from this thread (BCA pencil barrel and Farrowtech stock with A2 tube, or Smoke Composites stock, should take it down to about 3# 5oz or so). Get on it boys!

What buffer setup?
 
I wondered how to do that with a 300 Ham'r pencil barrel from Wilson Combat, TA lower, Lightweight handguard and grip, some Ti parts including BCG. Then lightweight in the butt stock. Is a buffer spring lighter with flat wire or round? Just silly questions that come up as I haven't assembled very many ARs and I really don't know much about them. I still go through a tutorial so I won't miss anything, hopefully. Be well Brothers, Bearded Gnome.

I'm new to AR's with this project, so I don't have all the answers. But, aluminum bcg is lighter than Ti, and barrels are interchangeable/don't matter other than port or no port AFAIK

Edit: and aluminum is massively less expensive
 
My Shaw barrel was shooting 2moa to 3moa groups today. Nothing seems to help. Any thoughts? I trust the scope. I checked the mounts. Its a lighter rifle but I did better with a 308 with a less comfortable strand worse trigger. I'm not sure it's just the lightness

2026 300 blackout diet complete, the folding stock is gone (the majority of the weight loss) and a whole bunch of milling complete, chasing grams at this point...All the bare metal is where an end mill kissed this. Milled off a bunch of picatinny, the gas block is skeletonized, milled pockets in the handguard, brass deflector is gone, a few holes here and there. There are still a few areas I can attack like the barrel nut and buffer tube but here are the results.

3.4lbs dry or 54.5oz.

My suppressor puts it at 4.2lbs but if I'm willing to throw money into a new can I can get this at 4lbs even with a Scythe Ti or something in that 7oz range.

Think I'm happy for now, Next up is a re-zero and range trip where I can finally get y'all some accuracy results.

What load are you running in it? My Shaw is a 1 in 7, but seems fussy with 77TMKs. It's more consistent with 73ELD-M.

This is the 300blk! I may be the only one running wholly subsonic in here. I've been using the Callaway Boar Axe 195g to wonderful effect in the faxon 1:5T barrel
