MOA from lightweight 16" AR barrel?

[RingSteel]

I've got a heavy AR15 upper (.223)that I'm really pleased with, and now I'm wanting to build a lightweight upper. which barrel would you recommend that is lightweight, .223, and still can produce MOA accuracy?

If you not going to turn it red this may be a Good choice..

More options..

any of these should do MOA...Most are 556,But will shoot 223 just fine..

Re: MOA from lightweight 16" AR barrel?

This will do MOA and is a lot less $$. Built one upper on this barrel a few weeks ago; got it broke in, now need to wring it out with a good optic.

Re: MOA from lightweight 16" AR barrel?

The rainier select 16" isn't super heavy.

edit: there was a 169$ daniel defense carbine barrel on sale at midway awhile back it had decent reviews. I wouldn't expect more than about 1.5 out of any light chromed barrel though.

Re: MOA from lightweight 16" AR barrel?

Centurion Arms with good ammo can shoot MOA. Profile is between a Government and Pencil. I would think the Wilson Combat would shoot better but it depends what your intended use is going to be (chrome lined vs stainless).

stripped 16" barrel weighs 26.1 ounces
low profile gas block weighs 1.9 ounces

Re: MOA from lightweight 16" AR barrel?

I can hold moa with a stock stag arms 16" bbl. But it is free floated, a buddy of mine has a 16"bbl in his dome (not chromelined) and he is sub moa. Depends on the shooter too.

At least light enough for me and what I want to do with it. Yea the Noveske is lighter. BFD.

Re: MOA from lightweight 16" AR barrel?

I see your point; maybe I have something different at home as I think there may be an error on his web site right now. Will check it when I get there.

Per these specs below, yes the one in the link is heavy.

http://www.ar15.com/forums/t_3_12/515711_.html&page=1

All good on 223 loads. Thanks for the offer.

Gotta remember - this one is "normal" for me, plus I add another 1.5 pounds to it!

Re: MOA from lightweight 16" AR barrel?

Thanks for the great input. To clarify, I'm looking to build a lightweight bug-out carbine. I guess I'm addicted to the sub-moa accuracy that my heavy upper gives me - but it's way too heavy for a toting gun.

Pencil barrel is what I'm thinking about... is MOA a pipe-dream in the pencil thin barrels?

 

[9H_Cracka]

Re: MOA from lightweight 16" AR barrel?

We put this rail on. It is super light and offsets the weight of the barrel.

Re: MOA from lightweight 16" AR barrel?

The barrel contour has nothing to do with accuracy, but rather how fast your barrel will heat up.

fwiw, Molon posted this a while back. I can't find the original post to see what shooting conditions these were shot at.

No. However with accurate "light" barrels your groups will grow faster than with a heavier barrel.

Why do you care if it's 1MOA or 1.5-2MOA if it's a "bugout" carbine? I have a 762x54R PSL that shoots 1.5MOA on a good day and I don't have much problem ringing a 1foot wide steel plate at 500-600 yards. Pretty much any carbine barrel free floated with decent ammunition should perform just as well. Not much reason to ask for more than that form a "bugout carbine."

It's true that it doesn't need to be 1MOA, but since I'm building a new one it would be really nice if I could pick a barrel that would allow that level of accuracy for at least the first couple of shots. Head shots on zombies... bwaahahhaaaa.

Re: MOA from lightweight 16" AR barrel?

My Noveske N4 14.5" is a consistent sub-MOA shooter

 

[sf88]

Re: MOA from lightweight 16" AR barrel?

I consistently get sub-moa results from my Scar's skinny pencil barrel.

 

[Raider Power]

Re: MOA from lightweight 16" AR barrel?

My colt 6920 (no mods) has been surprisingly accurate. I'd have never expected it to shoot as well as it does. It is easily in line with the results above. I know of two other 6920's (owned by family members) that shoot just as well too. Unless you're just wanting to build a rifle, I'd just look at getting a 6920 and being done with it.

Re: MOA from lightweight 16" AR barrel?

I own a DD LW mid length 16" hammer forged. It is fairly accurate for a LW chrome lined barrel. Haven't done real accuracy testing with it as I don't intend for it to be a bench gun. I would guess 1.5 MOA with match grade ammo. I have it in a VTAC Extreme (similar to Troy Extreme) 11" rail and it is a super light handy package.

I also own the Centurion 16" LW mid length that was listed earlier. This is a phenomenal chrome lined barrel. It is sub MOA with my hand loads. This is essentially the same barrel used on Noveske's N4's (good barrel too if you can find one parted out). If I were to recommend one barrel for an AR, it would be the Centurion. It is not a true LW sort of a hybrid between gov't and pencil/LW. I have this mounted in a 12" DD Lite and it is feels lighter than a gov't profile in the same configuration but no where near as light as my DD LW (rail is part of the weight difference).

Re: MOA from lightweight 16" AR barrel?

Diemaco (now Colt Canada) had 14.5" pencil barrel C8's for some time in the Canadian Forces - with good ammo and a FF tube on them they would be sub-moa, however when hot they wandered badly, and with a suppressor they strung very badly.

They have since gone to 16" heavier profile guns.

At what temperature do you consider the barrel to be HOT?

Re: MOA from lightweight 16" AR barrel?

while not as light as a pencil barrel. I really like gov't profile. nice weight but with good stiffness at the end of the barrel.

Re: MOA from lightweight 16" AR barrel?

Wilson combat Just sent me there 1-9 556 Recon 16" Mid Fluted barrel and its looks Nice ! 37 OZ before being fluted I will ring 500 rounds OF LOT TEST 75match threw it this weekend from 100-750 yards..

I know its Not a light weight,But if its a shooter there light weight model(27 OZ) may be worth a look..?

 

[RingSteel]

Re: MOA from lightweight 16" AR barrel?

Thanks for the input. I'm looking into the Centurion barrels right now.

I hadn't thought about including a lightweight forend to the equation to help keep weight down also.

Not being able to touch it without feeling discomfort is hot enough for a stainless barrel. Chrome lined barrels can tolerate a little more.

A pencil or lightweight profile barrel will heat up faster but also cool off faster than a heavier contour barrel which takes longer to heat up but also longer to dissipate that heat.

Re: MOA from lightweight 16" AR barrel?

I think I see the OP's point with this type of a build. You see, zombies don't respond to suppressive fire - they just keep on coming, undeterred. Therefore, if you are to stop them, well placed shots are essential.

As they generally travel in packs and come at you in waves, the ability to pick them off in a precise manner allows you to conserve ammo.

I'm thinking yea, MOA out of a lightweight barrel is a great idea.

OP, are you Mayan?

 

[msalm]

Re: MOA from lightweight 16" AR barrel?

I built a lightweight upper for a coyote rifle a few years ago on a Rock bbl. I turned it down to 18" with a .675" gas block and tapered the barrel under the free float tube (RRA mid-length). It's about the lightest I've made and it honestly suprised me with 3/4 - 1 MOA accuracy. Shoots very well for the weight and is handy as hell calling coyotes in the midwest.

No idea, I actually started shopping at a store that's a little more expensive than anyone else in town (but has a very good selection) just to avoid the zombie talk that plagues the other 3.

Also for the OP, you will get heat stringing but remember that the lightweight profile will also cool much faster than its heavyweight counterpart.

1 mag rapid - or two to three mags slow fire deliberate.

Generally they group quite nicely if you fire a 5-10 rd group.
If you fire a 5 rds group - then a mag very quickly - then another 5 rd group you will see your group open up a fair amount.
