Yes, I would like to receive special offers, and to hear about new products and brands. The AR is a rifle comprised of two halves; the upper and lower mated together, each responsible for their own essential functions.

The upper contains the bolt carrier group, and is the half of the AR the barrel attaches to, so making the right selection of upper parts to match your desired performance is critical. Buy Now. A significant advantage of the upper — unlike a lower receiver — is it's not considered a firearm by the Bureau of Alcohol, Tobacco, and Firearms.

This means you can purchase the upper and have it shipped right to your door, no FFL transfer and no paperwork. A shooter can assemble a variety of upper configurations and use all of them with the same lower. Meaning you only have "one" serialized firearm.

Having two dedicated rifles is certainly an option, and if you want to get the absolute best performance from each specialized set-up, that is probably the way to go. Many manufacturers offer a number of options when it comes to AR uppers, so what are the most important things to consider when choosing your next one? What makes a good upper receiver? While there are many versions of the AR upperthe most commonly available version on the market today is the flat-topped A4-style upper that does not feature a carry handle.

So, what are uppers made of?

BCM Cosmetically Blemished Complete Lower

They come in a few different types of material and use different construction methods. This makes it easier to work with in the manufacturing process, but it is not as stress-resilient or as strong as T6 which can be as hard as steel.

Receivers, both upper and lower, are made one of two ways; they will either be a forged receiver or a billet receiver.

A CNC machine completes all the work, taking the solid block of material and trimming it down to the exact size and shape required. After the initial size and shape has been achieved, the receiver is then finished on a CNC machine. It is generally agreed upon by metallurgists that, because of the compressive forces involved in the forging process, a forged receiver is stronger than a billet receiver.

The shaping of the receiver under pressure causes the grain of the metal to follow the same shape as the receiver itself, providing for continuous grain characteristics in the overall product.

These are by far the lightest of any aluminum receivers, but also very much the weakest. They are made by pouring liquid aluminum into a form, or cast, and letting it solidify. These are usually finished on CNC machines as well. There are also a few special cases where companies will offer polymer uppers, usually reinforced with metal in key places.

These are far less common than lowers made of polymer which are rising in popularity and viability as a cost-effective option, and they are only a viable option for uppers if you are looking to build or convert an AR in. When it comes to uppers, there are three ways to make your purchase.Forums New posts Trending Search forums.

Jun 1, 49 NC. Thinking of using one of these to build a short 5. I have used a couple of the standard BCM upper receivers and they have always been great. What is your experience with these? May 27, 7 22 38 north carolina. Reactions: Dan M. KZP P. Mar 11, 69 Raleigh, NC. I bought one and the blemish was insignificant. My only complaint is my barrel daniel defense would not fit in the upper, even when heated up first.

I put my barrel in the freezer for an hour then blasted the upper with a heat gun. Still no go. I had to spend some time sanding down the interior of the upper so the barrel would insert. Once it did go in, it almost immediately locked in and wouldn't come out by hand. Going to be a real pain to change if I decide to.Electroless Nickel Teflon has continually proven to outperform traditional Anodizing and Phosphate coatings by leaps and bounds!

The increased reliability, corrosion resistance and ease of maintenance make this upgrade a no-brainer. These imperfections are very common but are usually hidden when anodized. Nickel Teflon does not hide them as well. In no way shape or form will these blemishes affect functionality.

When using a clamshell type receiver block, the contact points may cause slight discoloring on the exterior of the receiver. This of course is strictly cosmetic. However, if you're trying to avoid discoloration then we recommend using a pin type receiver vise. The inside diameter for barrel extension is slightly undersized for a tighter fit to the barrel and a more accurate rifle. Email me when Back-In-Stock.

Benefits: Run it longer and harder - Lubrication optional. If you decide to use lube you won't notice when it dries up. The natural lubricity of Nickel Teflon has a much lower coefficient of friction than phosphate treated steel with lube applied. Lubricity and wear resistance - Lubricity plays an essential role in optimizing wear resistance and longevity. Nickel Teflon has a. Longevity - Has a Hardness of Rockwell Guaranteed not to peal or flake Ease of maintenance - No scrubbing required.

Carbon fouling literally just wipes off with a rag. Corrosion resistance - We apply a proprietary Electroless Nickel substrate with a higher than average phosphorus content, giving the coating a barrier that's practically impenetrable by corrosion.

Send Transcript Close.Upper receivers with baked in carry-handles and iron sights have been relegated to history. Optics are now synonymous with forward deployed combat carbines, featuring modular "optics ready" flat top upper receivers. Driven by a sense of urgency to improve lethality and save American lives in real-time, this innovation has inadvertently introduced a degradation in the rigidity of the upper receiver, with the weakest point being the area around the ejection port.

Shifting mass from non-critical to critical areas; the BCM Mk2 Upper Receiver reduces barrel deflection and enhances bore tolerances improving barrel alignment, consistency and accuracy.

This enhanced rigidity aids accuracy by limiting barrel deflection from external loads such as a bipod or vertical grip. Also prevents unwanted deflection of moving components, reducing the chance for premature damage and wear of the bolt and barrel lugs which results from misalignment. In addition to weapon optics, suppressors have also become standard in modern combat operations.

With added gas expansion areas and new channels added around the charging handle opening, vent gas away from the end user's face, reducing distractions when employing the weapon system with a can. Fine tuning the positioning of the forward assist creates additional clearance for right hand sided charging handle manipulation and clearance for end plate mounted slings. All of these improvements come without affecting the manual of arms employed in manipulating a Mil-Spec upper receiver.
