I got a Bear Creek 16" contour profile barrel for 6.5 Grendel.  I mounted a YHM QD FH for my Ti Phantom and the groupings were around 5 MOA and all over the place.  Without the suppressor on it grouped about 1.5 MOA.  These were both 10 shot groups using Hornady 123 AMAX, factory loads.

I found that the shoulder area is .700 just before the threads.  For suppressors and QD devices, I don't think there is enough shoulder.  Both Silencerco and YHM both require a minimum of .720.

I don't know if for sure that is the issue or not.  The can looks aligned, I see no shadows.  Maybe the barrel doesn't like a can period, don't know.  I like it, bought a complete upper, but now need a new plan for deer season since I won't be using this upper, at least the barrel, looking at a different barrel now to replace the BCA with.

Anyway, FYI.

Granit Ridge Outfitters has Ballistic Advantage barrels on sale... I just got two... and they have free shipping.





My recent Faxon 20" acquisition on a group buy likes the 123 SST and 123 ELD Match when suppressed...





The Faxon is .740"...

Was looking at the 16" Faxon or the BA one, thoughts on either?  Not both.  

Thought I would post the pics of what I had.

Going to replace the BCA barrel with Faxon or BA and use the rest.

The flyer was definitely me and where the hits are was up, I had put the target on sideways.  10 shot group.  Without the suppressor.

BA hands down...

Just found an Odin Works 16" ultra light off of the EE with an adjustable gas block and the gas tube for $240.  I have had excellent experience with my 18" OW DMR, so looking forward to this!

Ive ran that exact setup for a little over a year and have nothing but goods things to say about it. 1-1.5 moa GROUPS not group using factory Hornady Black. .75-1 moa GROUPS not group using 123 ELD-M handloads. It also loved the 100gr Nosler BT and 100gr ELD-M

Even with a 16" ultralite barrel I was ringing 12"x12" steel at 810 yards with a 9x scope consistently. 660ft asl.

IMO the ILGS with the tunable gas block makes for a very very smooth shooter. I was able to get mine to function flawlessly from hot 123gr handloads to factory 90gr TNT loads.

You wont be disappointed.

I really wish that AA sold their 16" extreme LW melonite alone instead of only in the upper package deal.

My 16" lite is really cooperative even with the cheap Wolf.  These  have a 1:7.5" twist which
would be advantageous with heavier bullets.

Even with the package deal it runs $300. This includes an upper, gas block/tube and charging handle

6.5 G Extreme LW upper kit

As a package deal that really isn't priced all too bad.

I was considering the AA 16" LW, but their weird thread size is just a no go for me.  I don't want to buy a barrel and then have to spend another $90 or so dollars for a muzzle device.

What exact device? There are actually more than I first realized, out there in that thread pattern.

A quick google search will show you

More along the lines of current muzzle devices I already had instead of having  to buy new ones.  If I recall when I originally looked at barrels when I first started looking at the Grendel, I don't Griffin Armament has that thread pitch.

CNC Warrior, and Rousch Sports both have several varieties of FH's and brakes priced relatively inexpensive.

CNC Warrior also has thread adapters to 5/8-24

Can you have someone cut that?

My plan was to get a 16" and have someone like ADCO cut down to 12.5" and rethread to fit my suppressor.
I'll have to check my suppressor mount. I only have the AAC 762SDN6 for .30 cal.

AAC has mounts that index off of the muzzle so the shoulder shouldn't be an issue. You might want to confirm but I know that I have some 300 black out barrels that don't have enough shoulder so I use those mounts.

The barrel is good IMO, but I always shoot suppressed, so just easier for me to sell.  I got an Odin Works 16" Lightweigt with adjustable gas block off of the EE for $240 so went with that.  The shoulder on that measures .746.
