WTF are "bolt sprockets"?...

5.200" buffers in .308ARs are Rifle Buffers, and Rifle Receiver Extensions (9 11/16" internal depth, across the board), and Rifle Recoil Systems. They are not Carbine Recoil Systems, that will accept collapsible stocks. Only Fixed Rifle stocks. 5.4oz buffers are what you're looking for, as mentioned by @edgecrusher - or as damn close to that as you can get.

Tejas has a very very low energy reserve - because they've never needed a higher energy reserve. The Glenn Beck program tonight went over a whole lot of this on tonight's show, so it's worth searching and listening to. Very good info on the "why" this is happening to Tejas right now. Not the temps - that can't be avoided - but the blackouts that are fucking people up...

What's been referenced above would make a very solid build. Very solid. Having troubles myself, finding parts, I broke from my comfortable pattern of Aero uppers and lowers, Aero handguard, Armalite springs, this and that. This is an AR15-based gun, there is a pattern, and all parts fit, unless that particular company just flat-out sucks. All parts work together. I had the LaRue 6.5G BCG sitting here from the 18" 6 ARC build - that's in here. Bought the Faxon Gunner 12.5" barrel. Gun Pusher John has Ergo complete lower parts kits that included a grip - and man, let me tell you, that is a fine lower parts kit. He also had the Strike Industries extended charging handle, and he saved me an Aero lower, of the X15 markings. Bought a few Shockwave Blades several months ago - getting ready for this pistol-revolution by JoeBama and the BATFE... Also picked up a few KAK Shockwave Blade pistol receiver extensions. Had the Sprinco White spring here from the LaRue 6.5G kit (wasn't used in the 18" 6 ARC, went VLTOR A5 on that). Been sitting on an OLight Odin Mini since those came out. Went with GunTec USA for the 12" rail, and found a ZRO Delta upper receiver on JoeBob's Outfitters for $65. Had an H2 buffer sitting in the parts box, so I'll try that out in this one. Still needed an ejection port door and a couple small things, and I nailed a Timber Creek billet port door at Sportsman's Warehouse last weekend - along with those other little small parts. Gun Pusher John has the scope on order for me, but I'll still need a LaRue LT-158 mount for it. Other than that, I have a 12.5" 6 ARC gun. Getting hung up on brands and parts right now is just crazy - GET the good parts that you absolutely NEED - and get the other stuff where you can find it, here and there. There's really no time to sit around and wait for your perfect parts list to become available - not in these times.

At least the humidity inside is low, so the guns are safe... On a serious note, Tejas is really getting fucked up right now - it is bad.

Oh. I finally found it.

Those 168s will do that well. 168s really start running out of steam when you're going for something 800 yards +. Great out to 600-ish. Beyond that, it's time to start looking at 175s or more. That's the whole reason I asked - didn't want you getting committed to a projectile (and the load development) that might let you down, depending on your expectations for the gun.

I don't get it, brother - it's 54* on my back patio right now, in AZ. At 10:50pm. We're not that far apart, and all this cold shiit is missing AZ big time. That's crazy...

So, I DID snag one of the Faxon 12.5" 6 ARC barrels, a couple weeks ago, when they dropped. I did this for two reasons. First, I built an 18" Grendel SPR-type rifle several years ago, and it knocked my socks off with how well it did at distance (850 yards). Right after that, the Grendel Forum was doing a group-buy on 12" Grendel barrels, and I missed that one barely, so I bought a Faxon 12.5" Grendel barrel, publicly released. Built that thing up, and right after it was built, we had a Spring Shoot... and me, @Matt.Cross and @JBMatt shot that short little bastard at 850 yards with 10.6 mils of dial on the 4x Leupold scope. FLOORED, with it's performance, that it even got out there, accurately... Second, I built a 6 ARC 18" SPR profile barrel from Ballistic Advantage, as soon as this cartridge was announced, on 3 Jun 2020. I had the barrel about a week later, and had a gun together mid-July last year, and was shooting it. Blows Grendel away, for distance. Ran that bastard out to 850, and it was a pretty good difference - but it was also 105* when we were shooting. Weird ballistics, in that kind of heat - but it did better than the Grendel did. So, this all ties into Grendel-work, on 18" SPR BA barrels, how that ties into the Faxon 12.5" barrels on Grendel for comparison against it, and the initial 6 ARC work with the BA SPR barrel... which is a WINNER!... Yep, pulled that Faxon 12.5" Match barrel for the ARC... I have a plan for the gun, and it will be badass. But, I ran load development on the 18" ARC, and managed to get better groups over the Hornady Match 108 ELD-M ammo, on my 18" gun with my own handloads, and at a lower extreme spread. Hornady Match loaded ammo was 2616fps with an ES of 48, and I worked up the handloads (with Accurate 2520) to 2680fps and an ES of 41. That works. That works into a load in the 12.5" of 2493fps... Which is just NUTS! If all this works out like the math says it does - this is a supersonic load to 1,050 yards, from a 12.5" gun. There's more coming... hold onto your pants...

In ARKYSAW?!...

Okay. NOW you have me jealous...

See.... you thought we were just snobs on the .308 Winchester cartridge, through semi-auto platforms... If it goes BANG! when you pull the trigger - we love it here... Thought you were gonna "get out some weird shiit" talking about that .243, didn't ya?...

^^^ I'd risk it. If I can get it to do a burnout, then it's ON...

Stick with projectiles in the 80~100 grain range for that twist, and watch those getting to the 100-gr mark pretty close. That's about the limit for a 1:10" twist on a .243. I've got a Rem bolt gun with a 1:9 1/8" twist, that I'm still working on loads for, but I'm hoping that twist let's me shoot the Hornady 108gr ELD-Ms well, and the 103gr ELD-X even better. Hornady makes a 90gr GMX that would probably kick ass in that barrel of yours.

Eye distance - both apart, and to other facial features. I think you're good, brother...

He looks pissed. How's he doing with the horses?

What's the goal for this gun, man? What distance do you want to take it to? Asking, in reference to what you'll be reloading.

Going with heaevybuffers is SUPER easy to do, and you'll get fast shipment (even on a Sunday, I've found), and a top-notch product. He can sell you the buffer and the right spring at the same time. There's a bunch of different ways you can tackle this, also. I'd suggest going through this thread to get acquainted with the parts, dimensions, weights, and the WHY - of how it should be this way:

Well, you are NOT a small guy... That steak makes sense, knowing that...

NICE HAUL, BROTHER!!!

Run the .243. It's just a .308 Win case necked down to 6mm. 6mm projectiles are amazing. What twist rate is the barrel that you have?

Man... They are maxing that crescent wrench out, they way they have it set up.

Picked from the field of Ranger Instructors (RI's) that are stationed at Ft Benning, in 4th RTB. That's the first phase of Ranger School (Ft Benning, and 4th RTB), and where they do those demos. It's staged/presented out at Victory Pond, at the Water Confidence Course. Here's what it is - this is some family-wife video, so that's her backdrop music - but you get the gist of it:

Looks Legit!
