What is the best AR15 caliber or what do you own? I have the 5.56, but think I want another upper.

My vote goes to the 6.8SPC. Another good choice is the 6.5 Grendel. For choices smaller than .224, the .204 Ruger is a good varmint caliber. Brass for all the non-.223 calibers is pricey, and the AR kicks the hulls out all over.

I would have to go with the 223 but would really like to have one in a big game hunting cal.
Heredoggydoggy if you are talking about the extration you know that can be modified to land right next to you

You can? That would be nice, mine eject forward of the firing line and are hard to retrieve.

Yeah, I've got a shell catcher. Works good at the bench, but makes an AR even more gagety to carry in the field. One solution is to build an upper in .20 Tactical: .223 brass necked down to .20. Almost as potent as a .204 Ruger, and brass is cheap. Not a readily available upper, though--at least not yet.

You (gunsmith) can lighten the extractor to where it falls right next to you, My neighbor did it to his so he doesn't shower the guy next to him at the range.

Ive got a 5.56. I no boring but its what they had. Just bought a dpms flattop .223 upper for it . I know its basicly the same thing i had ,only the 5.56 wasnt a flattop. Thought about a 6.8 or .204 but the funding wasnt there.

IronMike · « **Reply #7 on:** February 28, 2011, 08:12:12 PM »

My AR is a .308 and I like although I haven't shot it much, my other choice would be the 6.8

400out, if you are looking for an AR in .308 you can find mine in the classifieds.

Thanks

I would love to have it, but without a job I think I would be hung from my toes if I did

Wanttohuntmore · « **Reply #9 on:** February 28, 2011, 08:31:30 PM »

Might want to look at the 6.5 Grendel. I read that it's quite nice. I'm still using a 223 though. Would like to add a 204, and an ar10 in 308.

Any calibre other than 5.56mm is only built on an AR frame.

The AR-15 was developed as a lighter, 5.56 mm version of the AR-10

I thought it was the other way around. Didn't see AR-10s until a few years ago, but the AR-15 has been around for more than 50 years.

The 6.8 is the newest member of my AR family, I built it with the plan in mind to replace my Ar-10 during Deer season as well as for Coyotes. I just like the lighter smaller Ar-15 platform better than the 10. I have Ar's in 204,223,308 & 6.8 , but If I was adding a new upper & I already had a 223 I would jump up to the 6.8 just for the increased bullet weight & ability to carry force down range to 500 ish. The 20 tac & the 204 are distance shooter but if you don't get the pump station you might be loosing a dog.

I absolutely LOVE my 25 WSSM! Antelope hate it though. Mike Milli at Dedicated Technologies built mine and will do my next one as well.

Looking at one in 17 Remington, or one in 20 Practical. I like the 20 Practical better than the 20 Tactical as the brass is a lot easier to make...one step up, no annealing, and no shoulder change so there's no fireforming. Plus the guy that invented it lives in Vancouver.

I've got a 6.5 Grendel upper that I haven't had a chance to wring out yet, due to the weather.

My wife wants a 25 wssm in carbon fiber wrapped/tensioned so it won't be as heavy to carry.

chrisb · « **Reply #15 on:** March 03, 2011, 08:51:48 PM »

I have and voted for the .223 but am in the process (slowly) of building a 6.8 to hunt with

I thought it was the other way around. Didn't see AR-10s until a few years ago, but the AR-15 has been around for more than 50 years.

The AR-15 is based on the 7.62 mm AR-10, designed by Eugene Stoner of the Fairchild ArmaLite Corporation. The AR-15 was developed as a lighter, 5.56 mm version of the AR-10. The "AR" in AR-15 comes from the ArmaLite name. Armelites’ AR-1, AR-5, and some subsequent models were bolt action rifles, the AR-7 a semiautomatic survival rifle and there are shotguns and pistols whose model numbers also include the "AR" prefix. ArmaLite sold its rights to the AR-10 and AR-15 to Colt in 1959. After a tour by Colt of the Far East, the first sale of AR-15s was made to Malaysia on 30 September 1959 with Colt's manufacture of their first 300 AR-15s in December 1959. Colt marketed the AR-15 rifle to various military services around the world, including the U.S. Navy, Air Force, Army, and Marine Corps. The AR-15 was eventually adopted by the United States military under the designation M16. However, Colt continued to use the AR-15 trademark for its semi-automatic variants (AR-15, AR-15A2) which were marketed to civilian and law-enforcement customers. The original AR-15 was a very lightweight weapon, weighing less than 6 pounds with empty magazine, though later heavy-barrel versions of the civilian AR-15 can weigh upwards of 8.5 lbs.
Today the AR-15 and its variations are manufactured by many companies and have captured the affection of sport shooters and police forces around the world due to their accuracy and modularity
The trademark "AR15" or "AR-15" is registered to Colt Industries, which maintains that the term should only be used to refer to their products. Other AR-15 manufacturers make AR-15 clones marketed under separate designations, although colloquially these are sometimes also referred to by the term AR-15.

Interesting--I never really looked into the history of the AR, even though I own 4-1/2 of them. Thanks KB.

BlackRidge · « **Reply #18 on:** March 07, 2011, 08:25:40 AM »

Thanks for the info Billy, gotta love the history behind it

I chose 6.8spc simply because its an inexpensive round that still allows you to hunt big game in WA state with your AR, BUT if given the option, would have gone with the 6.5 grendel. The ballistics on it are absolutely amazing

Other than that stuff, the .223 seems to be ideal for it IMO

KillBilly · « **Reply #19 on:** March 07, 2011, 07:34:06 PM »

In reality, I own 1 AR in 5.56/.223 and my second is a .243 WSSM on an AR platform. The .243 is a caliber I like and I made this choice after Rainshadow killed a nice cougar with his. It is an awesome weapon especially with the AR Gold trigger assy. It pulls at a smooth as butter 1.5 lbs.

Kowsrule30 · « **Reply #20 on:** March 11, 2012, 03:02:02 PM »

I gotta go with wear my heart is... So the 243 is my choice... My friend has a 308 and is a tack driver as well...

That's what I said also, so I built one from various parts. I enjoy shooting the. 223 for plinking and accuracy, but there's a TON of gratification in pulling the trigger on the Beowulf and knowing whatever you are aiming at will explode!

JohnVH · « **Reply #22 on:** March 14, 2012, 03:27:52 PM »

6.5 Grendel!

thinkingman · « **Reply #23 on:** March 14, 2012, 03:41:24 PM »

6X45 is my next build.
Great ballistics, great bullet selection, brass is easy to form, run the same bolt, very efficient cartridge.

MichaelJ · « **Reply #24 on:** March 14, 2012, 03:58:56 PM »

Some guys been running them in .260 and loving them as well...

Since this topic started, I have a barrel on order for the .20 LBC in an AR 15 platform. It's the Grendel cartridge necked down to .20 cal. Should be a screamer, but talk about the ultimate wildcat. Info on it is practically non-existant!
