Assembled in Charleston, South Carolina, with high-quality materials and workmanship…delivering All-American hardware at an unbeatable value. The upper receiver is forged from 7075-T6 aluminum, the hardest and most durable material of any upper, then Mil-Spec Type III hard-coat anodized.

The barrel is made from 4150 chrome moly steel, and features phosphate coating to increase durability and reduce wear. The 15" Keymod handguard is made from aircraft-grade aluminum, and free-floated for maximum accuracy. It's a nice start to your build…that's also USA-made and super-affordable. Can't go wrong here.

CBC 5.56 NATO/.223 Remington AR-15 Upper Receiver, 24 Barrel is rated 4.8 out of 5 by 4.

Rated 5 out of 5 by Wess from Great shooter I bought this upper to shoot predators and have ended up also using it to take several deer, hogs, along with many other things. It is a bit heavy to carry but one should expect that from a 24” bull barrel.

Rated 4 out of 5 by T1959 from Went together easily. Received my CDC upper and it went together with my Vulcan lower easily. Attached a 6-24x50mm scope on it and will sight in the scope while breaking in the barrel. Good price for a lifetime warranty on a made in USA product. Will try and update after some range time.

This upper has no specified BCG that is meant for this combo. Like any upper receiver, I recommend all bolt carrier groups that do not come with the upper receiver need to be head spaced for max compatibility and this is done by getting checked by a gun smith. <div class="bvseo-author">Answered by: Joe Product specialist</div> <div class="bvseo-pubdate">Date published: 2017-07-04</div> </div> </div> <div class="bvseo-question-answer" data-questionid="2061646"> <h2 class="bvseo-question"> What is the actual weight of this particular upper assembly ? </h2> <div class="bvseo-question-detail"> </div> <div class="bvseo-author">Asked by: DWag</div> <div class="bvseo-answer" data-answerid="2328979"> Thank you for your question.
