Is it a range toy like an SBR 308 or does it have a practical application
I am curious about how that round will perform from a 10 inch barrel

They perform great out of a 10", a good bit more energy than 556 and 300bo of similar length.  Although it seems 12" seems to be the sweet spot for it.

I am putting one together next weekend with a Lilja 12.5" barrel. I will report back with results. With a 12.5" barrel it's supposed to have MV of 2250-2300 FPS, and even with a 10.5" barrel I think you're still looking at 2200 FPS. Pushing a high BC bullet that doesn't bleed velocity really quickly it should be a hell of an SBR round.

Mine is a purpose-built hog killin SBR that I can feel comfortable using for a 200 yd shot on a large hog, if necessary. I don't really feel comfortable using a 300 Blackout for that (it was my other consideration). Being that I don't care at ALL about shooting subsonic rounds out of an AR, the 6.5 Grendel was a no-brainer.

I am waiting a 12" from the Grendel group buy.  Will report back on findings.  Plan to run cheap 100gr Wolf primarily, suppressed.  Debating on RDS vs Steiner 1-4x.  Also have 10.5" in 300BLK and 5.56, curious to see how this performs at longer distances.  Based on what I have read this might be the do it all rifle for up close and out to longer distances.  I am really impressed with the cartridge out of my 16 and 18" barrels, even with the cheap stuff.

I'd love to have a 12" grendel but I just don't think I can justify another caliber at the moment.  I have 223, 308 and 300blk covered.  I've taken deer with the 300 but the grendel would be better just for the extra range it gives.   If I get a grendel I'll have to go all out and buy a bunch of mags, ammo, good glass and reloading stuff for it.  My wife would kill me.

That sounds awesome! I love my 300 but I do not see it going beyond 100.

First off I'd disagree that SBR 762s are simply Range toys. 13" scar ring a bell?

A 12" 6.5g would be sweet but I can't stomach it at this point

Yeah I kinda snicker when people call a 308 SBR useless and then start talking about the 300blk.  A 12.5" 308 has nearly twice the muzzle energy of a 8" 300blk

his experience was enough for me to create my own 12.5" 308.  My only complaint so far is even suppressed she's LOUD

Take an 11.5" 6.5 Grendel with the 129gr ABLR (factory load BTW) and shoot it next to a 20" .30-30 with the 150gr Hornady RN:

11.5" 6.5 Grendel with a 129gr ABLR gives you:

100yds 2066fps 1223ft-lbs
200yds 1928fps 1065ft-lbs
300yds 1796fps 924ft-lbs
400yds 1671fps 800ft-lb





20" barreled .30-30 with a 150gr RN Hornady:

100yds 1879fps 1176ft-lbs
175yds 1599fps 852ft-lbs
200yds 1515fps 764ft-lbs



An 11.5" 6.5 Grendel has more energy at 400yds shooting a lighter bullet, than a 20" .30-30 does at 200yds. This is one of the easiest ways to show the layman how effective BC is compared to a known cartridge that dates back to 1895, and has been used to harvest untold numbers of deer and even large game at close range.

I'm thinking about cutting my 16" carbine gas down to 10.5", and leaving my suppressor on it. What are some potential problems? Gas port issues? Buffer? Thanks for any advice.

Depends on the suppressor construction, particularly the baffle alloy and how the baffles are mounted.

What suppressor do you have?

I suggest using an adjustable gas block on any SBR with a can. I prefer the SLR block. I like to use low mass carriers and standard buffers and Springs, then just tune the gas down. Makes for a very smooth set up.
Link Posted: 4/26/2017 12:54:08 PM EDT
[#13]
The longer you keep your bolt locked, the better with and without a can.

Torsion on the bolt lugs is exacerbated if you unlock too early, especially with suppressor back pressure.

They've broken a bunch of M110 bolts this way, but the M110 bolt is HPTd, which is why it fails, unlike the SR25 bolts.

The can weight added to the barrel increases carrier bounce if you shoot AUTO, so that is another consideration.

I would look at carrier weight, buffer weight, and adjustable gas.

If the Tavor was chambered in 6.5 Grendel with a Geissele, it would be worth keeping as long as the accuracy is there.

yeah it's still heavy as hell, every time I pick it up with the can attached it feels like picking up my 14lb bolt gun.

The only bullpen design I have worked with that felt lightweight and well balanced is the AUG.

They still are heavier than an AR15.

My Lilja 318 barreled Grendel is 7lbs 12oz with 2.5-10x32 Vortex Viper PST.

I'm looking at buying a 12-12.5 barrel in 6.5 and just found the 6.5 forum with the group buys.  I bought one of the bolts recently and would love to know were they stand on the barrel purchases.  The first page only shows 1 sold and I know it is more but at the same time, I do not want to wait until next year to build this year's hunting rifle.  I wish I could find a reasonably priced 12.5 barrel.

BFT paid to have all the barrels made, the 12 slots are a sure thing and will be built next month.
If you want one you better jump on it now, having a completion date already I would think will make them a quick sell.

You can still get in, the faxon is a very reasonably priced barrel. 11 left. You should have it by June for sure so plenty of time to build and get ready for deer season

Cool, I signed up at the site but can't post yet.

You guys pushed me over the edge... I have a 12.5 6.8II that has served me well, but what's another caliber to add to the loading bench.

If I buy the 6.5G 12" barrel for a pistol build I still need to fill out the paperworkout for the barrel as if it could be built on a SBR?
Thanks

No.  It's a pistol if you configure it as a pistol without a stock.

No paperwork other than normal transfer of your lower, which you probably already have.

The caveat is using a lower that was not originally fully assembled into a rifle.  So if you are starting from scratch you will have no issues federally, but always check your state laws for any conflicting issues.

According to the group buy forum, the 12" barrel only has 4 more openings.  Go reserve your spot if you want a decent priced 12" barrel from Faxon.

I asked before but i dont think you saw it. I plan on doing something similar, i even have the same rail in a parts bin somewhere, but mine is the 12 inch version. DO you think the 12 inch version would cover the muzzle? As that is something i dont want it to do.

Typically your rail needs to be about an inch shorter to keep behind the shoulder of the threads. I think 3/4 shorter will be right at the shoulder, so a 12" barrel needs an 11" rail or less if you don't want to tuck muzzle devices.
