NOTE: This upper assembly has a barrel less than 16” in length. These uppers are intended for use in AR pistol or legal short-barreled rifle builds. Other configurations may violate Federal law.

This Bravo Company AR-15 Barreled Upper is made from high-quality materials and assembled with an attention to detail to ensure you get an upper that is reliable, accurate, and durable. This 5.56 barreled upper features an 11.5” barrel that is machined from Mil-Spec steel with an increased percentage of Vanadium and Carbon, which keeps the barrel rigid in all types of environments and temperatures. The bore and chamber are chrome lined to further increase the lifespan of the barrel while the outside dimension is finished with Manganese Phosphate for additional corrosion resistance. With a 1:7 twist, this barreled upper receiver group is optimal with 62 grain 5.56 Mil-Spec ammunition and is high pressure tested and magnetic particle inspected to ensure it will stand up to the higher pressures. If you are looking to build an AR pistol or SBR, the BCM AR-15 Barreled Upper is one of the best options.

Money well spent - No regrets

Super stoked that I could finally scoop one of these up as they sell out all the time...and for good reason. It's BCM so that means it's top quality and ready for anything. Primary Arms has the best price by far and their shipping is incredibly fast. Thanks Primary Arms, always a pleasure!

As expected from BCM, this is a spectacular product. You can tell immediately, even before picking it up, that it is going to be awesome. It not only came with the barreled upper, but it also came with some cool little free items like a BCM hat, some posters of BCM rifles, a QD m-lok piece to attach a QD sling, a m-lok rail attachment for mounting picatinny items, and some BCM stickers and decals. Then you tear open the bubble wrap tightly wrapped and taped around and at both ends of the upper, furiously ripping it up like you are 5 years old on Christmas morning. You get this beauty out and revel at how sweet it is. It is lightweight, perfect fit and finish, has the proud BCM logo stamped on it. It just feels right in your hands. You will never regret buying one of these, you just feel proud to have one. At least I do. BCM is not paying me to say this for the record, but ya know if they wanted to I wouldn't say no lol.
