So…6.5 Creedmoor or .260 Remington? Potato, potahto? Do you you reload or shoot factory ammo? Either way, DoubleStar has you covered. Their STARB10-BX rifle is now available in both the uber-popular 6.5 Creedmoor or .260 Remington if you’re so inclined. Here’s their press release . . .

Winchester, Ky. (March 2018) – DoubleStar Corp, manufacturers of high-quality, US-made AR components, rifles and pistols, is proud to introduce the American-made STAR10-BX™ rifle line with two new calibers: 6.5 Creedmoor and .260 Remington. The STAR10-BX line is based upon the popular STAR10-B™ Rifle, which elevated the power and precision of the AR-10 platform to a new level.

The STAR10-BX utilizes a 22″ stainless steel, free floating, heavy barrel with a 1:8 twist rate for added velocity. It also incorporates the STAR10-B billet aircraft 7075 TC aluminum upper and lower receivers anodized to MIL-SPEC. The flattop upper receiver features a brass deflector and dust cover, while the lower receiver features an integrated trigger guard and enhanced magwell. The STAR10-BX also features a CMC 3.5 lb. Trigger Group and the ACE™ Hammer™ Buttstock.

At an overall length of 45.5″, this semi-automatic rifle comes equipped with a low-profile gas block, Bullseye™ Muzzle Brake, Samson .308 Evolution (15″) Handguard, BCMGUNFIGHTER™ Charging Handle with MOD4 Latch and a Hogue® pistol grip. It also features a Nickel Boron Bolt Carrier Group and comes with a 20-round magazine. MSRP $2,549.99.

“Our new STAR10-BX is not only a piece of art, but when you get on the range with it you will see why it is one of our favorites. It will easily rule any range, shooting match or hunting field,” Nick Collier, director of special operations for DoubleStar, said.

      • That and it’s less than half the cost of the Doublestar. I’ve been wanting to collect No. 1s, and the RSI is kind of next up, but I’ve been watching the auctions and the M77 Hawkeyes with the full length stock seem to be really rare. These can be had for ~$900 shipped. I need to hurry up and finish a project so I can have some extra cash to invest (squander).

      • Shop around and you can find a S,R&Co Precision Rifle in 6.5 Creedmoor for around a grand. Considering the cartridge’s intended purpose, that’s probably hard to beat.

  1. It’s a nice looking rifle. 22″ is a good length for a Creedmoor barrel. My biggest gripe here would be the rifle gas length. I tend to lean toward JP’s school of thought with the XL gas length.

    Should you choose to build your own AR10, the Aero M5 upper is free with the purchase of the Aero lower at Primary Arms for the next few days. Pretty sweet deal.

  2. “Do you you reload or shoot factory ammo?”

    At this point 6.5 CM ammo is more popular and easier to find than .260 Rem.

    • I think that was the point. If you reload you can get (very slightly) more performance out of the .260, and find the accuracy sweet spot for your particular rifle. If you don’t reload, the 6.5 makes much more sense.

  3. Doublestar? Double no. Got burned with their .223 model and while I like the .260 this model will not even be in the running.

  4. For that price I would expect an adjustable gas block, a premium trigger such as Geissle or Timney, and a stock for long range shooting like a Magpul PRS. I did not look to see how heavy the rifle is, but, if for hunting you can build a rifle in the 7-8lb range minus optics or a heavier precision build for a few pounds more, depending on barrel profile and BCG choice at the same price point. 6.5CM is a long range cartridge, and I would expect a high dollar build like this would reflect that.
