Decided to build a 6 arc instead of a 6.5 - 3404speed - 03-08-2022

Hey guys, i received some good advice on here but ive been swayed to the 6 arc. I dont plan to reload and 6 arc has the most reasonable factory match ammo available. I plan to do mostly bench shooting and always wanted to touch 1000 yards, i know its not easy but its kinda a bucket list thing now. I know the 6.5 grendel is a capable cartridge but decided to go with the 6arc purely for the long range capabilities over the 6.5 grendel while sacrificing some of the hunting capability of the 6arc.

I ended up ordering a 20” 6arc upper from atheris.

Heres the specs, from what i could find the barrel is supposedly machined from liberty blanks made by saturn

Atheris Forged Mil Spec Receiver
Atheris 416R Stainless Steel Barrel w/ 5R Rifling
Guaranteed Sub MOA (1"@ 100yds)
1:7.5 Twist
Atheris Black Nitride BCG
Atheris 17.5” MLOK Handguard
Strike Industries Charging Handle
Adjustable Gas Block (Option)
Strike Industries Dust Cover
A2 Comp or Thread protector included (Depending on current stock)


Ive researched quite a bit and the only negative thing ive been able to find is the lead times. Estimated around 14 weeks.

I know its not a precision firearms or odin works or larue but it was in my price point. $600 shipped. We will see.

I plan on running a aero m4e1 lower with a larue mbt-2s trigger with a magpul prs lite stock and a anarchy outdoors precision rifle grip along with a magpul bipod.

I guess the good thing about the lead time is i have enough time to research a scope lol

I figured the 6 arc isnt too bad since its 6.5 grendels slightly smaller brother lol

I've got both and like both. The 6Arc is probably better for reaching 1K.
There is a sister forum for the 6mm ARC, 6mmarc.com, you'll find lots of info there, several guys belong to both.
