6mm arc upper

Radian Weapons make a quality upper. I have an 18” mod 1 complete rifle that is a great shooting rifle. I have consistently run 5 round groups from .5” - 1.5” with either 103 eld-x or 108 eld-m factory loads. I’ve shot 15 different 5 round groups shot on different days to get that spread. Out of those groups only two were over .8”.

100% US made, lifetime warranty and an moa guarantee.

what velocity are you getting in the 18 inch barrel?

Better to build by yourself or use a good gunsmith with quality parts. I bought an Odin upper for $1,000. It went back for warranty. It was very under gassed, even with suppressor and gas block fully open. They also changed the slick upper to a forged upper.
When it came back, it had same gas problem and worse accuracy. I contacted them again and they said no. I decided to take it apart myself and send to gunsmith.
When I took it apart, I found the barrel nut was only hand tight. I sent it to a gunsmith to open the gas port and assemble it correctly and replace handguard because it their was flimsy and sometimes touched the gas block.Cost was $100. Now it works and shoots 1–1.25 inch 10-shot groups.

When I decided on length, my upper is 18”. I use all available information and recommendations for. But learn in my area of hunting and great 6arc ballistics 12.5” would be more than enough.
 
I’ve one 6ARC uppers, two I’ve built, all were gas guns.

The one I owned was a Wilson combat 18” upper. Shot great, was accurate, but it was a heavy rig.

The first one I built was an 18” BA barrel in an Aero Precision set up. Also shot pretty good.

The last one I built is a 14.5” proof research inside a BCM rail/upper. That dude shoots wicked good. It belongs to a buddy and he is having fantastic results with his reloading setup he’s using.
 
The rifle Justin mentioned is 10lbs 6oz fully loaded for the field. ARs themselves are inherently heavy compared to a bolt gun. Generally all metal parts with very little composite materials. I find the extra weight aids in shoot-ability and recoil. To me a 10lb rifle isn’t unwieldy or cumbersome to carry all day in rough terrain. But it’s probably not for everyone.
