Product Details: AR-9 Complete Upper Assembly – 16″ / 9mm / 1:10 / 13″ CBC Arms Gen 2 Keymod AR-15 Handguard / Rail with BCG & CH

➲ Upper Receiver

The foundation of all good ARs is built upon a dependable upper receiver. CBC upper receivers offer best-in-class quality while providing you years of dependable service. Boasting a MIL-SPEC type III hard coat anodized finish and machined from 7075-T6 forged aluminum, this M4 flat-top receiver delivers a lifetime of superior function. You want your AR built upon a solid platform - this receiver gives you the confidence that your AR-15 will function when it counts most.

➲ Bolt Carrier Group

There is nothing more crucial to the performance of your AR-9 than the bolt carrier group. Manufactured to MIL-SPEC and finished with a superior quality nitride finish that protects against corrosion and heat, this 9mm (GLOCK STYLE) BCG will not let you down. To ensure that it will provide superior performance in your AR-9, each bolt carrier group undergoes high-pressure testing (HPT) and magnetic particle inspection (MPI). Designed for both standard and lock-back operating systems, this 9mm bolt provides heavy-duty performance and reliable cycling.

➲ A2 Flash Hider

The muzzle device is designed to perform a specific task, like suppress flash intensity or reduce felt recoil. This A2 Flash Hider is machined from quality steel and finished with an exceptionally corrosion resistant salt bath nitride for a lifetime of service. It provides effective flash suppression that preserves the shooter’s night vision by disrupting the muzzle flash when firing in low light conditions. While its closed bottom with top and side ports offers reduced dust signature when shooting from the prone position while additionally acting as a compensator.

➲ Barrel

The barrel is one of the few components that directly affect the accuracy and weight of your build. Designed for corrosion resistance, this barrel will not let you down. This barrel is machined from 4150 Chrome Moly Steel, heat treated to RC 28-32 hardness, and properly stress relieved. This barrel has a nitride finish for increased strength and durability. It is chambered 9mm chamber, with a 1:10 twist rate. This is the perfect barrel for an AR9 build, keeping weight to an absolute minimum, while still offering a significant ballistic advantage.

➲ Standard MIL-SPEC Charging Handle

A central component of your AR-15, the charging handle not only assists in chambering a round, but is your main tool to clear a round that won’t eject cleanly. The 7075-T6 aluminum design results in a rugged and capable charging handle for your AR-15. With lightweight aluminum construction and a traditional snag-free latch design, this charging handle provides superior function and reliability.

  1. Chris Little

    Very nice finish as usual from CBC. Cannot beat the price anywhere. This is my 7th upper from them and none have been the slightest disappointment. Lower is a NF Dedicated 9mm with Glock 33rd mags. Topped with a Vortex Venom and Hogan cartridge trigger. Nice combination.

  2. Kenan

    This upper is of excellent quality, I have fired 500 rounds so far without any issues. Using this upper on colt lower and it worked flawless. Way to go CBC, I really like the quality parts that you use for this upper.

  3. Bardownpilot (verified owner)

    Purchased to run in Steel Challenge. Runs well on a standard AR lower and MIL Spec trigger group. Ran mostly lead cast reloads, runs better than I can. Handrail is slim profile. BCG ran well on stock AR spring and standard minor power ammo, tested with ENDOMAGs. Works reliably (post magazine break-in, see Endomag website for details on that). Heck of a deal. Well done CBC

  4. Jared Reviea (verified owner)

    I bought this thinking for the price, I can’t go wrong. I’m glad I did. I’m running a spike’s dedicated glock lower with a Franklin armory fun trigger. I have a 6.55oz buffer, and it has eaten up anything I’ve thrown at it, including cheap steel cased ammo. Best $260 I’ve ever spent.

  5. timk444 (verified owner)

    I have fired only 80 rounds through this upper using a Angstadt dedicated lower, it works well with 1 FTF, but should be no problem after some more break in. Only 4 stars due to the charging block on the bolt carrier group not being staked. Overall good quality and a good buy.
