Odin Works AR 15 upper parts by blackrifledepot.com? By the year 1959, the Armalite Company was in the middle of some extreme financial problems, and were unable to manufacture or experiment more with their new rifle. To combat this, they ultimately sold off the design of the AR 15 to another gun manufacturer, Colt. Colt would later go on to become one of the biggest producers of the AR 15 platform for a great length of time. Around that same time, gun manufacturer Remington Arms was in the process of developing a new, small diameter cartridge with increased velocity, specifically for use as a medium-range rifle caliber. This .223 cartridge was then used as the basis of Stoner’s designed scaled-down AR 10 that he was experimenting with. This later went on to be named the Armalite Rifle 15, or AR 15 as we commonly know it as today.
Keymod vs M-LOK: Which One is best? While each system has its own set of advantages, disadvantages, and style, it will really come down to personal preference which one is better. In 2016, the United States Special Operations Command put the two systems through a series of tests to see which one was better. The purpose was to see which one survived rough handling, drop tests, failure loads and endurance tests. In the endurance and rough handling tests, both systems had zero issues. A difference came with a repeatability test, and M-LOK came out on top when it came to least amount of MOA shift when removing, then reattaching a rail with laser sight. Another difference was found in the drop test, when it was found that M-LOK accessories remained attached 100% of the time while keymod accessories only remained attached 33% of the time.
A common misconception about cold hammer forging is the “cold” part of the process. These barrels are usually done at room temperature. The pressure that is then generated creating these barrels does heat them up a bit, and the barrels must also be stress-relieved by further heating after forging. While this whole process can be done by heating up the barrels to extreme temperatures, today’s technology does not require it and is why it is called “cold” hammer forging.

16” AR-15 Upper Assemblies : For many first time builders, the 16” AR-15 Upper Assemblies are the sweet spot. I’d go so far as to say, for most people, in most circumstances, a 16″ upper assembly is the ideal all-around choice. With this size you get the most out of the rifle from a ballistic standpoint. The gun will be softer shooting, the concussive blast present in the shorter barrels is not a huge factor, and it’s an overall very practical length for a wide variety of uses. If pressed on what length to go with, we always recommend the 16” AR 15 upper assemblies over any other length we sell at Black Rifle Depot.

Many polymer drop-in handguards will be made of two different pieces that will fit around the barrel. They are generally fastened together by a handguard cap towards the front, and secured by a delta ring assembly in the rear. They get their name from how easy it is to install them, or to “drop-in” a new one. Installing them is super easy, and can literally be done in less than a minute. Simply pull back on the spring loaded delta ring to remove the current handguard, follow the instructions on the new one and put it in almost in reverse of removing one and there you go! Brand new handguard in no time! Most drop-in polymer handguards are offered in different lengths, in order to accommodate the varying gas system lengths of whatever AR-15 they are going on. They are generally the cheapest option, but they do have one slight disadvantage. Because of their design, they incorporate a handguard cap that is usually in contact with the forward portion of the barrel. This can possibly affect accuracy, especially if using fore grips or bipods with the handguard. This is not always the case, but something to be aware of if precision accuracy concerns you.
