New AR15 caliber...

[fly-by]

If only somebody could come out with a new/unique cartridge for the AR platform that could throw a bullet with a BC of .5 or better at 2700 fps from a 20-22" barrel. I might even consider owning an AR then!

LR-308 in .260 or 6.5 Creeedmoor.  7.9lbs with light profile 20" barrel and carbon fiber handguard.  Not that much bigger/heavier than an AR-15.  This one is in .260.

Yes, that would be really cool

You can get an AR-10 that should do what you ask.

I think the AR-10 style is the future of the AR market.  More manufactures are making parts and prices are coming down.

I've been trying to decide on buying a bolt action 6.5 creedmore or building a 6.5 creedmore AR

I hope you're right. I really want to build a 6.5 Creedmoor.

Having used both, I'm a huge fan of the AR-15 platform in lieu of the AR-10 platform due to size and weight.  Sure a .308 is nice and useful, but especially for hunting applications, this is a bit more than I think most people want to lug around.  The 6.5 grendel in the ar-15 platform is, in my opinion, the best of all worlds.  Low recoil, good for deer and maybe black bear sized game and smaller.  Probably a little light for elk.  Shells are getting pretty cheap... $0.35 a round for 6.5 right now for wolf ammo.

.308 is right in the same price ballpark, but its just a lot to carry that isn't needed most of the time.

Everyone's got their own thing though...

Yorke, There are AR-15s (not 10s) that chamber .243 WSSM.  There are .243 bullets that are .5+ BC, and the cartridge should exceed your 2700 even with the short 20 in barrel.

I built my dad a 6.5 Grendel. I love that thing. That's on my list of ARs I'm going to build myself.

I forgot about those! Anyone have any word on the durability of the WSSM uppers?

As far as the AR-10, they're just big enough to be too much. I'm only luke warm on the AR-15 because of the size and weight. The newer AR-10s are better, but still not doing it for me.

OK, fess up, that 7.9lb has to be without the scope & mount, or the bipod, right? That thing has to be close to 11 lb as pictured.

Yes, 7.9lbs bare.  Everyone will accessorize differently.  When I used it for High Power it just had irons and a sling and was less than 8.5.  My point was you are only starting out about 1.5 lbs heavier with the base rifle.  It's not my first choice to carry on a long hike but works great for camping out and glassing a big cut.   

I recently e-filed a form 1 to build a 10.5" SBR in 300 Blackout which will wear nothing but an Eothech.  Expect it to come in well under 7lbs loaded.

I hate to break the news to you but all form1 for SBR's were denied back in May and any not denied are on perma hold right now.  Even form4's and Can submissions are locked up right now.

Thanks for the heads up.  I just checked eforms and it still appears to be in process.  Created and submitted 5/8.  I'm actually more upset about the form 4 issue.  I was days away (based on current lag between check cashing and approval) from taking posession of a Specwar 7.62.  Sorry to get off the AR topic.
