➲ Muzzle Brake

A muzzle brake effectively cuts recoil and muzzle rise which permits you to make rapid-fire hits without having to fight to control your AR. This muzzle brake does an excellent job of keeping your rifle accurate and on target. 

➲ CBC Keymod Handguard

New for 2020, these AR-15 handguards are built to provide rugged, reliable performance. Designed with the advanced shooter in mind, these handguards are both sleek and ergonomic in the hand and that translates into faster on-target performance and ease of use. These AR handguards provide Keymod slots for mounting attachments and feature robust steel mounting hardware to ensure an easy rock-solid installation.

➲ Pistol Length Gas Tube

An essential component to your AR15 is the gas tube, which keeps your build up and running. This gas pistol-length tube is constructed from corrosion resistant stainless steel ensuring a lifetime of service.

➲ .750 Low Profile Gas Block

The gas block is a critical link in the chain that is too often overlooked. This component ensures that your AR runs reliably. Made from high-quality steel with a smooth nitride finish, this .750 low-profile gas block is efficiently designed to stay put with the percussion of gunfire. With its low profile this gas block allows it to fit under the most ergonomically designed handguards and rails on the market.

➲ Pistol Buffer Tube Assembly

This AR-15 Pistol Buffer Tube Assembly comes with everything you need to get your next ar pistol build ready. Assembly includes buffer tube, castle nut, endplate, spring & carbine buffer. The tube is extruded from 6061-T6 aluminum and has a matte black hardcoat anodized finish. This assembly features a snug fit to ensure no unwanted brace movement during pistol operation. In addition, it allows for any desired brace position with zero restrictions giving you the most comfortable fit and versatility. 

➲ AR-15 Lower Parts

The lower parts are integral to a reliable AR firearm. Our AR-15 lower parts provide rock-solid performance in demanding conditions.

➲ 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.

➲ 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.

➲ Bolt Carrier Group

There is nothing more crucial to the performance of your AR-15 than the bolt carrier group. Manufactured to MIL-SPEC and finished with a superior quality nitride finish that protects against corrosion and heat, our BCG will not let you down. To ensure that it will provide superior performance in your AR-15, each bolt carrier group undergoes high-pressure testing (HPT) and magnetic particle inspection (MPI). Whether you’re looking for a drop-in Mil-Spec quality replacement for your current AR, or are going for a new build, this bolt carrier group provides you with the reliability and performance you expect from a premium product.

➲ Barrel

The barrel is one of the few components that directly affect the accuracy and weight of your build. This barrel has a nitride finish for increased strength and durability. This provides not only an impressive barrel life but ensures excellent accuracy. The barrel threads are carefully threaded to the .308 standard. Optimized for stability with a 1:8 twist rate, this 300 BLK barrel can handle heavier bullets used for subsonic loads with ease.

    This kit is rock-solid! I bought two. Both came securely packaged. The upper assys are fully assembled. All you have to do it build the lower and match it to the upper and you’re done! I used Anderson no-logo multi-caliber receivers and they were a perfect match. No reaming required. Each pistol took about 30 or 40 minutes to complete. Well pleased with the kits and the price! Thanks!

    Bought this kit. All I can say is its AWESOME. Even used it in a YouTube video I made on 80% firearms. Several hundred rounds thru it. Performed flawlessly right out of the box. Installed the lower parts kit in my already milled Dayton Tactical lower popped on the pre-assembled upper and off I went. I recommend CBC for ALL 80% rifle and pistol builds anyone talks to me about. Quality for the price in unbeatable.
