Another 6 LB 15 OZ .308 with next to nothing recoil:
What kind of buffer system do you have in there?
My "Sugar Badger" build.
Honey Badger barrel assembly
Honey Badger Hand guard
Honey Badger Shorty Stock
Radian Raptor clear ano charge handle
All upper and lower parts are off getting "Tungsten" Cerakote
Stripped upper/lower are an SBR Registered PA set. (H-157 BRIGHT NICKEL for those interested.)
Probably going to buy "Literally the Best Trigger Ever Made" at some point.

As I learn more about the AR platform, I'm reasoning that this comes down to the balance between weight reduction of the rifle and tuning of the operating system.
So, I'm thinking a lightweight barrel is most of the weight savings, and would increase felt recoil, while a long(er) gas system, lighter BCG, heavier buffer/spring will decrease it. I suppose gas port size and the muzzle break are also factors. Am I missing anything?
On this particular build, did you already have a tried and true formula, or did you have to figure this one out from scratch?

A week ago I would've said the same thing. A Proof CF 16" 308 is 2lbs. A Wilson "Ranger" contour weighs the same. A Rainier weighs 8oz more. And there are variations in between. But that doesn't make a 9lb gun into a 6lb gun. Go to VSeven's website are check out their 22oz receiver set, titanium BCGs, magnesium foreends, and titanium lower parts and gas blocks. But these are $4K AR10's.
If you've followed MSTNs builds you'll see he's been up to these types of builds for a hot minute.
I definitely enjoy seeing his builds. Been thinking about paying his shop a visit if he has a storefront.
I actually meant for my post to be more of a question. After re-reading it, sounds like I'm trying to tell him what's what... I think I'll edit it.
I was just over at V7 looking for small parts to build out a lower.
I started really digging into the weeds on the AR platform summer of last year and am continually surprised at how much there is to learn and know about just ONE rifle platform.
I now have all these "head builds" floating around while I try to stomach the cost of accessories for just one rifle (financially, you can have 2-4 rifles, or 1 that's all "finished"
). Project I'm doing now is "what I would have done if I'd known back then." My goal isn't to build the lightest .308 gas guns. It's to build the lightest that will shoot MOA or better through a combat load out. Added bonuses are long term reliability, low felt recoil, and stunning good looks.
The biggest potential weight savings building an accurate but lightweight is in the Proof CF barrel. While you can make a stainless barrel as light as the Proof CF, the SS won't behave properly in terms of precision when it gets even a little hot. Forget about hanging a can off of a skinny SS barrel, too.
Where else to save weight next? Why not everywhere?!?
Bolt carrier group - A .308 actually works optimally with a low mass carrier, IMO. But not a 6.5CM!
Receiver set - V Seven makes some top shelf lightweight stuff.
Forend - Ditto above. And looks right.
Muzzle device - Ditto above, again. The V Seven Fusion titanium brake is quite effective and weighs next to nothing.
Small parts - Did I mention V Seven?!?
Furniture - There's a surprisingly large delta in weights here. And some really good lightweight choices.
Scope - Same as above. Kahles scopes are my choice here.
Scope mount - Not the smartest place to save weight. A Spuhr 9 ounce scope mount is strong enough to stiffen an upper receiver. That's my choice. But a 5 ounce Scalarworks LEAP mount can be very tempting.
Suppressor - When suppressing a gas gun, I've gone full on to CGS. Extremely lightweight and effective suppressors that require no muzzle device.

16" 308 barrels
Proof CF - 2lbs 3oz
Proof Steel - 2lbs 8oz
Rainier Ultra Match fluted - 2 lbs 10oz
Rainier Match - 2lbs 8oz
Rainier Select - 2lbs 5oz
Criterion Hybrid - 2lbs 5oz
Wilson Recon - 2lbs 0oz
Wilson Ranger - 2lbs 3oz
VSeven 16" w/ titanium gas block - 2lbs
A Proof Carbon is about 0 to 7 ounces lighter than the barrels I was looking to use. I would argue the biggest weight savings is in the optic and furniture. But all those things being equal, speaking strictly of the build itself, it really seems like if you want to shave real weight off it has to come from the receiver, handguard, and BCG. And maybe an aggregate of all the small parts if you can afford to go titanium.
ETA:
To compare 15" hanguards:
VSeven 15" magnesium handguard weighs 7oz
Wilson 14.6" handguard weighs 12.8oz
SLR Ion Lite 15" weighs 12.7oz
A VSeven magnesium handguard is half the weight of a conventional handguard and easily makes up for even the heaviest of barrels listed above.

I wonder if V Seven is using some special sauce in their handguards? I remember when BCM was using magnesium they had the lightest rails around, but they bent easily, and they switched to aluminum, calling it the KMR-A (they still make a big deal of the "alpha" on their product page, too).
I don't know. XLR makes a magnesium chassis now too
This is our version of a Ar15, just a little different. We made the upper the serialized receiver as it houses the buffer tube now. This is a heavier platform designed for precision. The rifle below is still a work in progress. This uses all AR parts internally, including the barrel, bolt/carrier, recoil system(carbine length) trigger group and mag. Early testing shows its a very solid platform and can handle bull barrels with ease.

Who makes that bipod? Thanks
The bipod is a UTG Mlock design. It is very rigid and I think made in the USA at their new and incredible plant.
You have fine taste in weapons sir.My 10mm with a Green DOT.
Thank You!
Crappy picture but here’s the workhorse 17S.

That is such a great gun. Maybe the perfect gun. Like the P210 to a pistol aficionado, the 553 is one of my grail guns! I hope to add one to my collection one day. I have a few US SIG guns that work well. Here's one that is 553 inspired, a Gen2 556R.
SIG SAUER USA has been on it and I've been trying to keep up. I am not doing to good at keeping up.

ACSS reticle ?
Been seriously considering grabbing up one of the PA prisms..
They look to be fairly nice mini-magnified optics for the money.
I like the 1 prism, the 3x prism has very little eye relief. I mounted one of the 3x and immediately took it off. I ordered another 1x from primary arms.
another shout for the PA 1X, I put the 9mm version on my AP5K instead of a red dot and I'm really impressed by the clarity, construction, usable eye relief/eye box- also that they included an adjustable diopter eyepiece....

Care to elaborate on what made you choose that can specifically?
The Osprey 45 ? Other than a 22, it's my only pistol can, so it ( along with a hand full of pistons), goes on whatever I'm shooting that day. I'm trying to find a Resilient RS9 or a Ca$h 9 in stock to dedicate to my PCCs
