➲ .936 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 phosphate finish, this .936 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.
➲ 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.
➲ 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.
➲ Rifle Length Gas Tube
An essential component to your AR15 is the gas tube, which keeps your build up and running. This rifle-length gas tube is constructed from corrosion resistant stainless steel ensuring a lifetime of service.
➲ Spiral Fluted 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. Due to being machined from 4150 chrome moly steel, this barrel contains a better cut, higher-definition rifling, crowns, and chambers, resulting in the ability to stay more accurate over its usable life. This barrel utilizes the popular and versatile .223 Wylde chamber, which allows for the safe usage of 5.56 NATO ammunition and enhance reliability. This is the perfect barrel for an AR build, keeping weight to an absolute minimum due to the fluting, while still offering a significant ballistic advantage.

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.

First time customer. Arrived in a timely manner. Customer service with Chris is superb.
Good quality and professional made product. Craftsmanship is flawless! Definitely recommend CBC to anyone!
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.

Ordered this expecting standard ar barrel what I didn’t expect is this beast, mounted it on a plum crazy synthetic lower it fit flawlessly took it out to the range and after sighting the scope in I was shooting 1″ groups at 100 yds then went out to 200 yds still a 1″ group very nice upper I will recommend to all my friends.

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.
