New AR Build Caliber

[USAF Ret]

Well, three polls on different sites and the answer is overwhelming.

6mm ARC it is.
Got my armorers kit and the lower parts ordered. Time to shop and get to work.

Good luck and enjoy.

I like books, although I know there are tons of tutorials on the internet. Anyone suggest a good AR build book?

 

[USAF Ret]

The deal is done. Just ordered a 6mm ARC 20" Ballistics Advantage barrel. I was weighing going with the 22", but this is a hunting rifle, so went with the 20. They have a sale going on, so it was a pretty good deal.

Really not complicated enough for a book, but it never hurts to search the library.

Really liking my bolt action 6mm arc. 105 grain bullet at 2750fps or a 55 grain bullet at 3550fps. All with around 30 grains of powder

I had a buddy send me the Brownells video. They are for an ignorant person like myself.

Once I get some brass, I will be loading up the 100 grain Nosler Partitions.

Midway had lapua 6.5 Grendel brass. Run through 6mm arc die and trim to length

For the 6mm Arc folks, what are you doing for brass? I have seen folks using 6.5 Grendel brass. I just don't want to get into annealing. Maybe just buy some Hornady ammo and reuse?

I just bit the bullet and bought loaded Hornady bullets-eldx. For factory ammo, my rifle shoots them really good

I built a BCM upper with 18” proof barrel. I’m shooting 1/2” grps with factory Hornady eldx s. Haven’t crono’d ; but as accurate as it is, i can just dial.
Its been fun on yotes. Not as heavy as a ar10 build. And that round actually hsst torn up the yotes, not that im into keeping fur.

I'm not really aware of any books either, all my education came from Arfcom back in the day. This caused me to try and remember all the cartridges I've had an AR upper in:

22lr, 223/556/Wylde, 5.7x28, 6arc, 6.8spc, 300blk, 9mm, 45acp, 450 Bushmaster, and 308 in a large frame. Its definitely a tinkerer's platform, like a semi-auto T/C Contender/Encore. I'm sure your build will go great, just ask if you need anything.

Much appreciated. Had a buddy point me to Brownell's videos and they are really good.

I had a BA barrel in 6.5 Grendel. It shot an easy 1/2 MOA out to 850 (as far as I shot it) with factory Hornady American Gunner. I miss that gun. You’ll like yours

What was your barrel length?

Sweet! Same one I got. Hope it shoots as well, but I am not an 800 yard shooter.

 

[USAF Ret]

Well, I pretty much have everything on order except the gas block and tube. Went Aero Precision with all hard components - lower receiver, upper receiver, hand guard and buffer tube and spring. Went with a B5 Bravo stock as it is more flared for a good cheek weld and has a soft rubber butt pad (I always end up replacing the Magpul buttpad with a Limbsaver).

Waiting on a buddy to give me a report on the Aero Precision adjustable low profile gas block.

 

[turbobrick]

I had good luck with the Aero adjustable. My 6arc upper really need some gas adjustment, but I was using a nonstandard lower, short barrel, and a suppressor so it’s to be expected. I like having adjustable gas when possible.

I plan to get a suppressor when I sell a few rifles, so that makes sense. I ordered it last night.
