Doublestar/JT might have 4 different 16" hbar barrels available right now for $99-125 with or without fsb and with or without chrome lining.* You just have to call instead of order from website.
No bolts though. Anderson has bolts and barrels in stock right now as well. *no affiliation to either besides proximity. |

I don't feel like reading through 25 pages. That being said. The group of guys I hog and deer hunt will all run 6.5 Grendel. We have barrels from 12.5 up to 24 and we use them all the time. I run my 12.5 for hogs with a Flir RS32 and it is a pig slaying machine. I run a 18 for white tail most of the time.

The LGS sold the 6.5G barrel/BCG combo but told me that they had another one coming in. This one had an adjustable gas block. Had just cleaned out the safe of the tired iron that was in it and used the consignment check to prepay for it. All I'll need is the rail and gas tube to be done.

horrendous business sense of the patent owner
Less rounds per lb than 5.56 Worse barrel life than 5.56 Worse recoil than 5.56 Worse parts wear than 5.56 Heavier rifle needed than 5.56 Under 200m terminal effectiveness much the same as 5.56 Average engagements are no where near 800m where the advantage kicks in Not standardized with other systems like 7.62x51 ....

Good to see people are emotionally-attached...
Yes the OP was why isn't it more common, and lists major AR manufacturers .... So pointing out disadvantages to the 5.56 seems pretty reasonable.... as that's its main competitor Point was missed about the 7.62 apparently... ... that people who want something more powerful tend to go with a much cheaper 7.62x51 rifle in the first place |

Hunting/match ammo is around $1/rd. Right in the same ballpark as .308. The real cost is building an AR in something other than 5.56. However the grendel forum's group buys are driving the cost down there too. |

There was no patent, there was a trademark and it proved the right decision until a major company, in this case Hornady would SAAMI it.

Recoil is heavier than 5.56 but less than 7.62x51 4. Parts wear is going to be less than 5.56 as Grendel is a lower pressure cartridge. 5. Weight is going to be about the same between 5.56 and 6.5 Grendel, AA offered a 5 pound rifle. 6. Terminal performance under 200 yards is not the same as 5.56, terminal performance of 6.5mm Grendel is drastically better, especially on big game. Grendel flattens things. 7. The advantage of the Grendel over the 5.56 starts at the muzzle not at 800 yards. It launches a heavier payload and has more retained energy at 300 yards than the 5.56 has at the muzzle. |

Agreed. Why the Wolf steel case ammo has been an absolute gamer changer for this cartridge. It has single-handed changed the entire market. Cheap ammo has a way of doing that. Keep in mind though how new the Grendel is compared to the .223 and .308. It wasn't very long ago you would be laughed at for hunting deer with a .223 Rem and it is not even legal to do so in some states. The Grendel on the other hand has worked well on elk..LOL |

Five years ago, before we got the Wolf steel, you may have had a point. Everybody was hanging fire, waiting for that promise, and the Russians took their good ol' time bringing it to market. The ONLY reason 5.56 is cheaper is NATO and the ginormous pool of ARs that never see anything beyond Walmart shelf stats. That almost invariably means 5.56/.223. .308 is much the same. No non-military chambering can hope (in brass, at least) to match them for price. If price point of the ammo is your only metric and you refuse to use steel in spite of just about everybody else using it in just about everything else, then, yes, 6.5 makes no real sense. I'm not sure where you're getting your stats from, but I suspect they're largely from the very early rifles with the 'type 1' chamber and bolt. Modern 6.5 doesn't have any of those problems. Yes the ammo is heavier You're firing a projectile that's twice the weight of the M855 in exchange for all of the benefits that larger bullet conveys. The rifle itself doesn't weigh noticeably more than its 5.56 counterpart. And, seriously, unless you're Force Recon or LRRP, is the weight difference seriously an issue? I mean, seriously? It's certainly lighter than .308. These days, more and more manufacturers are making barrels and rifles for the 6.5, Federal has started making ammo, Wolf is making steel ammo that's VERY competitive with 5.56 and 7.62x39. As time passes and more people jump on the train, more ammo manufacturers will cater to the demand and prices will drop. In a couple of years, it'll (with the exception of the cheap Wolf) be the same price as everything else you see on the shelves of your local sporting goods store.

AT THAT TIME, it was a breakthrough because it performed just about as well as the longer .30-06 in a slightly shorter platform. And still, even then, there was controversy, since most nations were looking for something with a smaller bore, while the US stuck stubbornly to our .30 cal doctrine. Things have advanced just a little bit since 1959. 6.5 bullets perform markedly better than 7.62 even in .308 sized cases. The 6.5 grendel was designed from the ground up to get as much benefit from that as possible while still being short enough to get into the mag well/chamber of an AR15. Why an AR15? Because 6 pounds is less than 9 pounds, the recoil, and particularly the muzzle blast from an 18" barrel is substantially less. Seriously, I, too, was once a .308 fanboy. I sold my G3 to finance a 6.5. |

Go to a ballistic calculator and run .308 vs .243 win vs 6.5 creedmor vs 6.5 Grendel and see what kind of numbers you're looking at. In similar length cartridges .308 gets absolutely smoked by 6mm 6.5mm 6.8mm 7mm. In shorter cartridges vs .308 you get extremely comparable numbers. The only thing .308 has going for it and HAD at the time too btw, Military studies BEFORE WWII recommend a smaller diameter (.276 Penderson to be exact), is that it's not 30-06 and we have alot of .30 cal components available. Don't kid yourself that .308 is in anyway a good cartridge, just about the only thing it's got going for it is it's ubiquity. |

And then I go on a 20 minute diatribe about how if I wanted a round that did what .300 BLK does id pull bullets from wolf AK rounds and reload them with 200 grain pills and fire them through my VZ-58 and enjoy sucking at life. Hell, You're better off ballistically with a lever action .45LC Marlin and hot loads than a .300 BLK. View Quote I like the idea of being able to shoot relatively quiet subsonics, or relatively effective supers with only a mag change. I also find it amusing that the ballistics are almost a dead match for the 7.92kurtz that the original STG was chambered for. It tickles my "everything old is new again" funnybone. What I don't find amusing is the near total lack of sub $1 per round ammo, and the very small variety and high price of even just bullets for reloading. I'm trying to figure out how stupid it might be to hard cast some heavy lead bullets for it. I've never contemplated shooting lead out of an AR, and I have no idea whether it's even feasible. Fortunately, I have a few options and some of those chamber very cheap ammo for plinking. Maybe by the time the HPA finally passes the variety will be greater. Meanwhile, I've got the 6.5. |

True, and now you got me thinking.... (And I'm genuinely curious I don't mean this snarky) What kind of barrel life difference are we looking at for 6.5 vs 7.62? Best info I could find was around 5k for the 6.5 and 9k for the 7.62 Though I read that some could get as much as 30k with 7.62 with mediocre accuracy View Quote View All Quotes View All Quotes Quoted:

You talk like the .308 went head to head with the 6.5 in military trials. The .308 was adopted in 1959. AT THAT TIME, it was a breakthrough because it performed just about as well as the longer .30-06 in a slightly shorter platform. And still, even then, there was controversy, since most nations were looking for something with a smaller bore, while the US stuck stubbornly to our .30 cal doctrine. Things have advanced just a little bit since 1959. 6.5 bullets perform markedly better than 7.62 even in .308 sized cases. The 6.5 grendel was designed from the ground up to get as much benefit from that as possible while still being short enough to get into the mag well/chamber of an AR15. Why an AR15? Because 6 pounds is less than 9 pounds, the recoil, and particularly the muzzle blast from an 18" barrel is substantially less. Seriously, I, too, was once a .308 fanboy. I sold my G3 to finance a 6.5. True, and now you got me thinking.... (And I'm genuinely curious I don't mean this snarky) What kind of barrel life difference are we looking at for 6.5 vs 7.62?

I'm going to bet ZERO.... |

You can fit it into a standard lower, GAME CHANGA for those who can't afford a $110 aero M5 lower

Good to see people are emotionally-attached... Yes the OP was why isn't it more common, and lists major AR manufacturers .... So pointing out disadvantages to the 5.56 seems pretty reasonable.... as that's its main competitor Point was missed about the 7.62 apparently... ... that people who want something more powerful tend to go with a much cheaper 7.62x51 rifle in the first place View Quote Much cheaper? Not really, unless we're talking about DPMS. |

View Quote As far as the super loads go, I really don't see any difference between them and 7.62x39 loads, which I can get for stupid cheap steel, or I can buy high end hunting Ammo that actually works. |

You guys got me all disappointed about my new 300BO build.
Good thing I'm also doing the 12" Grendel. Get both |

Your information is very dated and biased. .30 cal bullets are absolutely terrible, they're simply too fat to be aerodynamic. Go to a ballistic calculator and run .308 vs .243 win vs 6.5 creedmor vs 6.5 Grendel and see what kind of numbers you're looking at. In similar length cartridges .308 gets absolutely smoked by 6mm 6.5mm 6.8mm 7mm. In shorter cartridges vs .308 you get extremely comparable numbers. The only thing .308 has going for it and HAD at the time too btw, Military studies BEFORE WWII recommend a smaller diameter (.276 Penderson to be exact), is that it's not 30-06 and we have alot of .30 cal components available. Don't kid yourself that .308 is in anyway a good cartridge, just about the only thing it's got going for it is it's ubiquity. View Quote My mag length 20" bbl .308 load still performs better than my single feed length 24" bbl 6.5 Grendel load. |
