New from Colt Competition: AR-10 in .308

Colt Competition is the brand of Colt products designed specifically for the competition shooter. Until now they’ve only offered 5.56 AR-15 style rifles, but they’ve just introduced a rather nifty design in .308 . . .

Those who know me know that I hate it with a passion when a company makes a minor change to something and calls it a whole new rifle, and normally this would fall under the same category. But thanks to some engineering from the guys at Warne (yes, the scope mount people) this rifle comes with a remarkably adjustable gas block.

A normal switchblock gas block has two options — on, or off. So when you pop a silencer on the front of the gun, you’ve either got an over-gassed rifle that puts extra strain on the parts for no good reason, or a rifle that works more like a bolt action that anything else. Colt Competition and Warne came up with this fantastic solution: an adjustable gas block with 22 settings and adjustable without any tools at all.

The gas block is also available on their existing line of 5.56 caliber rifles. For those of us with cans its perfect, and even if you don’t have the stamp in hand you can tune your rifle to work precisely with the ammunition of your choice.

I have to admit, I want one.

    So is this an Armalite? Than it isnt an AR-10
    Call me picky… Maybe Colt should make a new name up to go with their new rifle and stop pulling AR-10 from Armalite’s name brand..

    1. avatar Ralph says:

      The AR-10 and AR-15 trademarks were actually owned by Colt, purchased from Armalite in 1959 when Colt bought the rifle designs from Armalite. Armalite sold out, making it Colt’s brand.

          About the AR-18, not the 10 or 15, but whenever I see “armalite” written out it makes me think of this.

      2. avatar brigo50 says:

        Can i put a Colt .308 upper on my Armalite lower and vice versa?

      You just got lawyered…

    Any idea on a price?

    1. avatar Joe Grine says:

      Street price: $1750-1800 for the 5.56 version shown above. The .308 version is not in stores yet.

  3. avatar Chris Dumm says:

    Do you use a bullet tip to adjust the gas system? I sure hope they don’t expect you to use your fingers on a sizzling-hot gas regulator.

  4. avatar Pascal says:

    Would you guys choose an AR-10 style .308 or would you with a Springfield M1A National Match/Super Match in .308?

    I was hoping for something for CMP or otherwise just for the range now that 400yrd one is available to me.

    waiting for a piston version

    1. avatar Joe Grine says:

      probably be a long wait.

    2. avatar GunDOc says:

      POF – pricey but sub-moa piston goodness.

    3. avatar Accur81 says:

      The POF Armory and LWRC Piston .308s are pretty accurate, although I would imagine that they are a tad heavier than this platform. They are also in the $3000 plus range…

      1. avatar Joe Grine says:

        That’s the beauty of this Colt – very light and points well. The weight of the can on the 5.56 version completely changed the feel of the weapon – I was surprised by this. Even so, both of them ran really nice, and the adjustable gas system allowed you to dial down the bolt snap.

  6. avatar Dyspeptic Gunsmith says:

    An adjustable gas block isn’t exactly a difficult or wildly new idea.

    The only reason why it hasn’t been seen more previously is that suppressors weren’t much of an issue before. Now people are starting to consider the knock-on effects of putting a can on a rifle.

    AR-10 is a trademark of Armalite Inc. Colt does not, and _*CAN*_ *_NOT*_, make an AR-10.

    Eugene Morrison Stoner (November 22, 1922 – April 24, 1997) designed the AR-10 while at Armalite. “At the request of the U.S. military, Stoner’s chief assistant, Robert Fremont and Jim Sullivan designed the AR-15 from the basic AR-10 design, scaling it down to fire the small-caliber .223 Remington cartridge. The AR-15 was later adopted by United States military forces as the M16 rifle.” (the notoriously inaccurate Wikipedia 🙂

    Colt is responsible for policing their trademark, but anything called an AR-10 had better be made by Armalite 🙂 .

      “AR-10 is a trademark of Armalite Inc. Colt does not, and _*CAN*_*_NOT*_, make an AR-10.”

      And yet – they _*DO*_. (Sorry to pick up your over-the-top emphasis style. Do you have it trademarked? Oh! My bad!)

      Hmmm. Then you badly need an explanation for why they do make an AR-10, and why there has been no action against them by Armalite. Without that, your sea-lawyering goes up in smoke.

      1. avatar BB says:

        Colt doesn’t make an AR10. Armalite makes AR10s. Colt makes 901s.

    The rifle is actually called the Colt CR-Pro 308.

  10. The Colt Competition Rifle Model CRL-20, caliber .308 Win., is listed on the Colt Competition website as the CRL-20, and is part of the CCR high-end PRO-Series. As far as I know, Colt Manufacturing Company LLC, Colt Competition Rifles, and Bold Ideas (now Bold Ideas Texas) have never referred to the CRL-20 as anything but a CRL-20. It is not a true AR-10 pattern anyway, but a SR-25 pattern and so uses the Magpul polymer .308 mags. According to the Vice-President of Bold Ideas Texas: The CCRs have always been products of Bold Ideas, not Warne Scope Mounts; Warne was a sister company of Bold Ideas until February 2013; Warne now has new ownership and is not affiliated with Bold Ideas Texas; The CCR fully-adjustable gas block is patented, all nitrided heat-treated stainless-steel, fully finger-adjustable, and has 24 settings as does the same gas block on the CCR .223/5.56x45mm Pro-Series rifles; Bold Ideas has no intentions of producing any CCR gas piston rifles in any caliber. And that is all I know about that!

      This is a very we’ll informed post, except for the gas block, that is a chrome-moly based steel that is phosphated, not nitrided. It IS an SR-25 platform, not a metric based AR-10 platform.

    Would you ladies put on your big girl panties and talk about the gun instead of who has what patent rights to what freaking name.
