➲ Upper Receiver

The foundation of all good AR's 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.

➲ Rifle Length Gas Tube

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

➲ .875 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 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.

➲ Keymod Handguard

Your AR-15 handguard has huge implications in terms of how much you enjoy your shooting experience. Our seven sided Keymod handguard is built to handle the hardest use and abuse of tactical and competitive shooting while offering more versatility than other handguards. It features a full-length picatinny top rail that sits flush with M4 flat top receivers allowing you to have more space for optics and back up iron sights. Due to the “7 sided design”, this rail has more than 200% more attachable surface area of a standard keymod rail. This AR-15 handguard is machined from 6061 aluminum, has a hard coat anodized black finish.

    She arrived on time and in packaging that was far superior to what I expected. The company was quick to respond to emails.

    This has to be one of the nicest looking uppers that I have seen. Tight and thorough workmanship. I am still waiting to get her to the range, but I know that I’ll be pleased. Between product and contact I have to say that CBC is an awesome company. I highly recommend!

    I have not been able to take it to the range, but when I do, I’m sure I’ll be pleased. Shipped out no later than the lead time, and i received it 3 days later; keep in mind there was a hurricane that week as well. I will definitely be shopping here again, thanks to everyone there CBC for providing an excellent upper for an excellent price.

    Order placed Oct. 1st, arrived Nov. 7th well packed. Upper is good, keymod handguard is good, bcg is excellent. This is my 3rd barrel and every one has had minor scratches through the finish from the installation of the gas block, most notably on the spiral flute edges. Chamber and rifling look good. With the exception of minor assembly marks, this upper is very good quality and is a bargain for the price. Shoots good groups. If you’re more on performance than looks, you’ve found a good deal. Four stars for assembly marks and long lead time.

    Received the upper in the stated lead time and was very pleased to find no issues whatsoever in quality or workmanship. Paired it up with a Bushmaster lower and it fit tight to the lower. I achieved groups of 1 inch or less at 100 yards, and with about 250 rounds through the upper so far, it is proving to be a very good buy. I will definitely buy from CBC again and would recommend friends to do the same.

    Have had my new upper on my rifle for about 2 months now and about 500 rounds through it. Only been shooting at 100yds so far and I’m amazed. Shooting just plain jane 55 grain federal I’ve been easily and consistently getting 1 moa or less at times. And even not having a threaded barrel/brake it’s so heavy that it soaks up all of the recoil. Great job gentlemen!!! I’m excited to get some nice loads and start shooting the legs off a ticks ass!!! Thanks again!!!

    I ordered this complete upper a few weeks ago on a sweet sale. Arrived pretty quickly. This upper is an outstanding value. Sighted it in at 100 yards and it’s shooting sub-moa straight out of the box. It’s now become my go-to varmint gun. Shots up to 300 yards so far and it’s money in the bank. I’d recommend this upper to anyone. It’s a great quality upper for a great price.
