One upper has an Anderson upper, Classic firearms 18" blued fluted barrel, cheap handguard, Anderson aluminum gas block.
The other upper has an unknown billet upper marked 6.5 Grendel from Antares Arms bought on gunbroker, cheap handguard, Anderson aluminum gas block, Shilen 18" stainless barrel.
Right now they share a charging handle and Toolcraft nickel boron BCG.

I put a sling stud on the stainless barreled to mount a bipod to.
The other one I put in an M&P Sport II lower for pictures. I think this one will be used in this configuration mostly anyways.
I want one for walking and the other for when I don't mind the extra weight. Both of these rifles will be used for deer hunting.
I hope to have some hunting pics with these rifles this fall.

If you want one to be a walking rifle, you might should consider:
Lightweight M-Lok or Keymod handguard. Cheapies can be had from ebay for as little as $20. You can spend upwards of $300-500 if so inclined to run Gucci gear. (I would not personally, but more power to you that can.)
Lightweight bolt carrier. I run one from Right To Bear arms. Can be had for $60 on sale. No bolt, just the carrier. Of course, you can spend much more on other brands like JP if so inclined.
Light-er, fast acquisition, low power optic. Something 1-4X would work. A 1-6x, even better. Leopold VX-Freedom can be had around $200.
Light-er gas block. The one in the picture looks pretty large. If you elected for the lightweight carrier, an adjustable gas block would be very beneficial. There are multiple light weight models on the market for under $100.
Of course... barrel profile would make a very big impact. But at that point you are talking about substantial change and money outlay.
I took them out today and shot some Wolf ammo through them.
I was able to get them on enough to smack the 100 yards steel in the wind standing offhand.
I put the new Grendel group buy bolt in the AIM Titanium Nitride bolt carrier. It worked every shot in the Classic firearms barrel. I fired about 20 rounds of the wolf ammo and 5 rounds of Hornady black through it.
My other upper with the Shilen barrel works every time with the Tool craft NiB BCG but when I tried first tried the Classic arms barrel and Tool craft bolt it would FTF almost every shot.

Looking to put glass on my new Grendel . Will the Nikon P 308 work or are the ballistics that much different . Its an A R style Grendel . I love that type of glass . have a P223 series on my AR that is great
That'll work. Just be aware that the BDC isn't anything more than a guide, you'll want to test things to see if you're still "minute of game" at distance. BDCs aren't usable in any application until verified, and most of the time they're deceptive. If your ammo and rifle produce variables identical - or very close - to the ones used in creating a calibrated reticle, fine. But the odds of that happening when buying a BDC off the shelf are very nearly nil.
Grendel is fairly close to 308, especially when you zero at about an inch and a half high at 100. That should make you generally able to hit paper plates out to 400 or so with the bdc. You'd want to test that.
