I want an ultra light AR for deer hunting and am considering the grendel at 4.6 # from alexander arms
Is there anything lighter?

How much does a LR-308 standard lower and stock weigh?

You will never get a .308 receiver set to compete with an AR15 frame in the ultralight game, especially if you use a Carbon 15 lower.  There is a point where recoil and weight need to balance, and I think 5 lbs is light enough in that regard.

I understand the AR is lighter but it will never be a great deer gun.
the 6.5, 6.7, 7mm-08, 243 & Grendel options are great deer calibers.

If anyone has a lr-308 lower please take a second to weigh it and let me know what i am looking at.

If anyone is aware of a ligher upper in the bigger caliber let me know as well.

Just some ideas for you.
In my own opinion, I think a scoped bolt action would be a better choice for a deer rifle, but that is just me.

Have you considered an LR carbine? The total weight of my AP 4 is about 9 pounds give or take including optics and ammo. Yet its so short compared to my Browning BARs that the extra couple of pounds is a small price to pay for the superior maneuverability and accuracy. Its a fine deer gun.

I actually think the AR is a better deer gun, especially in a High Performance Intermediate Cartridge chambering like the 6.5 Grendel.  Here's why:

1) You can actually train with it and not experience recoil fatigue or anticipation like you would from a .308, .30-06, or any of the magnums in a lightweight hunting rifle with a tapered barrel.

2) Since you can train with it, you can also get very proficient and predictable with your shot placement, meaning higher probability of putting the bullet through the vitals on game.

3) The inherent accuracy of the AR15 platform matches, and often exceeds the inherent accuracy of many production bolt guns.  All that is needed is a half-decent barrel, free-float tube, and a little trigger work.

4) It's cheaper to shoot the AR15 factory ammunition, like 6.5 Grendel, compared to most of your short and long-action hunting calibers.  It's even more true when you hand-load, since case capacity is much less than a .308 or larger case.

5)  Most .308's and magnums expend their energy on the backside of the animal after exiting, especially within common hunting distances of 200yds or less.  If you look at the .270 Winchester, a cartridge I grew up with and am highly fond of, you see that it really comes into its niche at 300-600yds, which is a very uncommon range span to hunt in unless one is truly married to the gun, and has spent considerable time with her at distance.

There are untold numbers of hunters proving this concept as we speak, and have been for a while now.

My bad. I somehow messed up the uppers.
I will get the 6.5 from Alexander unless i can find something lighter.
I have bunches of set up lowers and the Carbon 15 is minimally lighter.

I also however have money to upgrade my LR-308.
Its purpose id for the badlands of ND where i often shoot decent size deer from one ridge to another.
Range 350 yards on average.

Who makes a good compatible upper that can harness the additional power of the LR frame.
