The New ARC 300 Rifle from DoubleStar

ARC300

Designed as a “go anywhere” hunting gun, the new ARC 300 from DoubleStar is a 300 BLK rifle that is built to be light and tough.  ARC stands for Always Ready Carbine, and it appears to be a good choice for home defense in addition to bagging Bambi.

As with the existing ARC rifles, this is a direct impingement style gun. DoubleStar designed the gun to run both supersonic and subsonic rounds reliably, both suppressed and unsuppressed. I’ve run into a 300 BLK rifle that would not cycle subsonic rounds, so I appreciate the company taking the time to make sure this one will run any factory ammo.

While suppressed hunting has been legalized in more states than ever before, adding a can to cut the noise is very appealing for home defense purposes as well.

The 16” barrel has a low profile block and uses a pistol length gas system. A Big Timber Brake is mounted on the end of the barrel. Threading is 5/8″x24 for a direct attach suppressor.

DoubleStar chose a Samson 15” SX rail with M-LOK attachment points for the ARC 300. The stock is a Mortar Plate with a standard adjustable included. With an unloaded 30-round magazine, the gun weighs in at 6.7 pounds. Samson manual flip up sights are included with the gun. The MSRP is $1,370.99.

    Make one at the price point of a s&w mp15 and we’ll talk.

    Interesting muzzle device.

  • Flounder

    This is made by who?

    AND WTF!!!! WHY is it a pistol gas system on a 16″ barrel?

    • Hoplopfheil

      .300 BLK is why.

      • JT303

        What makes the pistol gas system better for a 300 BLK than a carbine or mid-length one? Is it specific to the round itself?

        • Kris

          A number of 300 BLK systems and 16″ barrels won’t reliably cycle and/or lock back with sub-sonics and a carbine length gas system. ONE of the solutions to that is a pistol length gas system…good gas with long dwell time for sub-sonics. But downside is that they may be overgassed for supersonics. Thus, many people run a adj gas block and dial it down. With a shorty barrel, the pistol length is pretty much a must have.

          There’s lots of ways to solve the issue, as it is a balancing act between gas system length, gas port size (up to the gas tube size…then it doesn’t matter), bbl length/dwell time, buffer weight, spring weight. The best manufacturers spend a lot of time making them all work in harmony across a wide range of cartridges.

            I see. Thank you for that.

          • Hoplopfheil

            Yep that’s what I was gonna say! Except not nearly as detailed. Nice!

          • Tom Currie

            As you say “The best manufacturers spend a lot of time making them all work in harmony across a wide range of cartridges.” But what does that have to do with THIS rifle?

          • iksnilol

            Somebody should make a 300 BLK SBR with a rifle length gas system.

            9 inch barrel + rifle length gas system would be sooo cool.

          • Russ Kell

            Ghost barrel 😉

          • Hoplopfheil

            Venting all the gas from the barrel before it hits the gas system? That would keep the BCG and receiver very cool indeed!

  • jonp

    Nice design but nearly $1,400? In this market I doubt they are going to sell many of these

  • Dr. Longfellow Buchenrad

    So is this overgassed on supersonic rounds? Im no .300blk expert, but pistol gas system on a 16″ barrel with supersonics seems a bit much.

  • Tom Currie

    Considering Double Star’s stellar reputation for quality and customer service, I suppose we should all run out to buy this gun. Absolutely no reason to worry about overgassing with a pistol-length gas system on a 16″ barrel. And clearly the gun is a bargain at this price from this manufacturer.

    SWEEEEEEEET!
