Looking for suggestions on 6.5 Grendel barrels. Budget is around 300 or less. This is mainly going to be a hunting rifle so I’m looking for a lightweight 16”. Preferably moa or sub moa. I’ve been exploring Faxon and Wilson combat as an option just seeing mixed reviews. Are there any better bang for your buck barrels that are around 1.5lb? Thanks in advance.
 
Bump your budget by 100-150 and you open yourself up to much better barrels.

Rainier Ultramatch
Lilja from Six Sigma
Criterion from PF

You can get a cut-rifled barrel from McGowen for $340 right now with their summer sale.
 
I run 2 6.5Gs, both with Rainier ultramatch barrels, a 12.5 and an 18, absolute titties, very accurate, easy clean-up, highly recommend. I ran mine this weekend next to a proof that cost 2X, the proof was lighter, but not any more accurate.
Wilson is trading on name now, not quality, in my opinion. I have been a customeer for over 25 yeas, going back to their 1911 hayday, I don't buy their AR stuff any more, too many good alternatives for same or less money.

Faxon is a value brand with decent performance, but nowhere near Rainier's ultramatch - in my experience.

Once you go below ~$350, you’re rolling the dice on whether or not you’ll get MOA/sub MOA.

I rolled the dice with one of the early Faxon group buy 12” Grendel pipes, which has a really heavy shank and overall heavy-for-length mass. It consistently puts 5rds of 123gr ELD-M into an inch at 100yds, and I regularly use it for shooting steel out to 800-900yds. 1st-round hits are pretty easy at 600-780yds on 2 MOA steel. I would not expect this performance from most $200-$250 pipes.

I have a 16” Lilja lightweight Wasp profile barrel that shoots bugholes, from the original Lilja group buy we did. It’s just one of those hummers.

For a 16” hunter, you’ll be fine with 1.5 MOA 5rd group performance anyway for a lightweight.

Either relax your requirement or up your budget a little as mentioned, but I would lean on scope budget more than biting it out of the barrel if it’s just for hunting medium game.

Now if you’re planning on extending the range a bit for coyotes, you really need a good shooter due to vital zone size and how skittish/fidgety they are.

Right now, there’s an excellent deal on Sons of Liberty Gun Works 13.9” MLGS Grendel barrels, but I have no experience with them firsthand to say how they shoot.

There’s also a good deal on some 13.9” Grendel pipes from Craddock.

My go-to sources for a while have been Precision Firearms and Lilja. I have at least 8 Grendels right now. I’ve been shooting it since 2009, starting with a 16” AA that I later gave to my brother. The main ones I take out are 18” LaRue, 17.6” Lilja, and my 12”. The 12” has been shot the most over the past 6 years.

Get a Rexus 6.5 Grendel Ultrabolt.

I have an 18” Rainier “Match”. I don’t have but 40 rounds through it but it’s shot really good groups from the start. Well worth the $260 price tag so far. Next time I put it on paper I’ll post some groups.

I have a couple of the Craddock RTR barrels on the way. We’ll see how they do.

I have a lightweight faxon nitride 6 arc. .750 all the way to the first taper. It needed some smoothing in the barrel extention. I only tried 1 bullet and power so far and it was easy to get shooting MOAish with a razor 2-10.

Craddock also now sells a 18" 6.5G barrel...

What you're looking for is actually no longer available unless @Constructor has a line on one. The AR Performance 16 inch 6.5 Grendel Barrel is excellent.

Outside of that, save your pennies and have Precision Firearms spin up what you want.

I know they’re “budget barrels” but I have 2 Ballistic Advantage barrels(16”&20”) that are sub moa with multiple types of ammunition. Really surprised how well they shoot
 
A couple of other sources:
I've had good luck with Satern / Liberty barrels for the Grendel
https://shop.saternbarrels.net/t/65-grendel

I have a couple of bolt guns with X-Caliber Barrels that shoot pretty well.
https://www.x-caliber.net/custom-ar-barrel
You'll have to wait for a 20% off sale, but X-Cal has them for every holiday.
They're generally spun up to order, so there might be lead time for one of their barrels.

Has anyone tried this SOLGW 13.9 barrel?

Also, the complete SOLGW 13.9" Grendel rifle with pinned barrel can be had right now for less than $1400.

Anyone have feedback on these?
I have been hesitant on SOLGW barrels, because a lot of them were Ballistic Advantage barrels... But, some now "appear" to be Black Hole Weaponry barrels.
The problem is... I would be willing to try BHW barrels.. but not BA barrels. And, I can't always Identify which one is made by who ?

Given the description of the linked barrel... I would tend to think it is a Ballistic Advantage barrel made to SOLGW specs, and is being "cleared out".

And while the allure of a bargain priced accurate barrel is tempting.... I feel like someone could easily spend the difference in $ in ammo ( between a more expensive "proven" barrel ) , trying to make that inexpensive barrel shoot to their expectations.

Thanks for chiming in. I decided to cancel my order for the solgw grendel barrel. I'm not interested in wasting a hundred rounds of ammo to find out it's not a shooter.

I have emailed Six Sigma and also called got the voicemail and left a message to inquire about ordering their 14.5 in Grendel. I've gotten zero replies. Does anyone have a line on if there's a problem with six sigma?

Last I knew all BHW, or Columbia River Arms or whatever they're called now, barrels were polygonal. Obviously you won't know that till you look down it though.

I have two WC 6.5 Grendel barrels. I'm not going to say that either one looks amazing under a borescope... but I don't really care about that.

My first one shoots in the 3/4 MOA range (5 shot groups) with target handloads consistently. The second one I've only ever put factory 123gr Hornady SST through, and it is consistently MOA. Both of them are lighter-weight profiles. For what I paid, I find it hard to put down.

If solely a target rifle, I'd probably look at other options.

Got to the range with my rainier ultra match 6.5 Grendel barrel a couple of days ago. No groups to show, but it is night and day better than the Odin works barrel it replaced. Hornady match shooting sub 1.5moa- and that’s as good as I need/expect for a SBR.

I found a load that the Odin barrel shot well, but it is/was super picky. The UM barrel shot everything I put through it acceptably. (I have an 18” Odin works barrel that shoots really well, so no shade thrown at them.)

FWIW... The only reason I think some of the SOLGW barrels are BHW, is because of the specs on the webpages being very similar.


SOLGW specs... specifically, "3 groove polygonal rifling, 1: 9.73″ twist rates" ( Odd twist rate ? )
And frankly the odd, twist is what made me poke around and look a little further
.
https://sonsoflibertygw.com/product/308-precision-barrels/
"Our Precision .308 barrels are 416R Stainless Steel with 3 groove polygonal rifling, 1: 9.73″ twist rates, and dimpled as always for secure gas block installation.
Choose from 14.5″, 16″ and 18″ lengths for your Mk10/Large frame precision needs.
5/8×24 muzzle threads"

( 6.5CM barrels from SOLGW are also "Our Precision 6.5 Creedmoor barrels are 416R Stainless Steel with 3 groove polygonal rifling" )


And ....
BHW, offers a .308 LFAR barrel in 416R with a 1n 9.73" twist. And "We use our Polygonal Caudle in P3 or P5 rifling known for its accuracy."

https://www.blackholeweaponry.com/store/18-0-INCH---30-CALIBER---PLATFORM-AR-308-p581525010

Conjecture on my part... yes. And heck, I sure could be wrong.... But, I don't know any other 308 LFAR barrel maker using a 1n9.73 twist.

My RTR 18" was delivered today. I probably will get around to installing it tomorrow or Saturday. I typically will use a cratex cone on a few places in the barrel extension so the rifle is nicer to the brass and I also shim the barrel into the upper. I will bore scope the RTR for the hell of it (just to irritate myself I suppose).

I've been playing with the Grendel since 2009-2010 so I understand it's general likes and dislikes. I've found it to not be picky assuming a good barrel and not trying to turn it into a 6.5×47. Good components and a warm load usually give good results.

The RTR is replacing a Rainier Arms Ultra Match 16" that I gave to my son to hunt with. I'm rolling the dice on the Rock Creek barrel but I'm not really concerned either way. The UM barrel is a solid 1" barrel @ 100 yards for 5 shots with Hornady 123SST factory ammo. More than good for his needs. I was a little surprised by how well the Hornady ammo shot. With the exception of some AA factory ammo in 2009-2010 I've never shot any factory ammo in Grendels

I've had pretty good luck with Hornady Black and the 123 ELDM Bullets. I've had a ammo lots that held 5 FPS SD and like 15 ES on my 20" barrel.
For hunting deer and hogs, I like the Barnes 115 TAC TX ammo. It makes two holes with a meat tunnel connecting them...
 
I didn't pack the Xero the day I had my son zero his new upper with the Rainier UM barrel so I don't know the numbers. The target seemed to enjoy the Hornady 123SST ammo though. I have many hundreds of Lapua and AA 6.5 Grendel brass but my son won't get any of that because he never police's his brass. When he pulls the trigger, and I'm not there, that brass is gone forever.

I did buy 3 boxes of the Hornady 108 6mm ARC ammo when I started with the ARC (for the brass). The sd numbers were in the 15 fps range but it too shot very well. FWIW, I have never even used the brass as my order of Starline 6mm ARC came in around the same time. I'm not a huge fan of Hornady brass when I can get either Starline or can convert Lapua.

Brass Goat. Even if the brass is destined for the recycling bin, a decent catcher means never policing brass…
I would like to say that might work, but he would just forget it. Youngish adult male with other things on his mind and living on his own. He mainly hunts so a piece or two at a time is lost. That is why I load his ammo with Hornady brass...

I installed an 18” RTR barrel last weekend in an Aero enhanced upper for my daughter’s hunting rifle. I didn’t have to heat the upper but it was as tight as could be before requiring heat. I tried 3 different factory loads. Aac 123 gr tipped, Hornady 100gr vmatch, and Hornady Black 123 eldm. Both the aac and vmatch shot 1-1.5 moa 5 round groups. It liked the 123 elds and over 4, 5 round groups averaged .8 moa. The barrel was gassed to run perfectly with an H buffer unsuppressed. No malfunctions over the first 60 rounds. Finish quality and accuracy/precision was on par with the Rainier Match barrel I have. So far, I haven’t gotten another barrel that shoots as many factory loads as well as my old ARP barrel.

I’ve never had feeding issues with any of my Grendels, I didn’t see a benefit in the larger feed ramps in the RTR.

While I’m sure there’s more precision to be found in a tuned hand load, I call it a win when I get a barrel that’ll shoot easily sourced factory ammo at or under moa.
