Magpul AR 15 upper parts with Blackrifledepot? The Colt AR 15 very soon found its way into military use in the early 1960’s, offering shooters in the United States Air Force and Special Forces a select-fire option. When the United States got into involvement with Vietnam in 1963, it soon became clear that Springfield Armory was not going to be able to keep up with the production of the standard M14 battle rifles. This was the perfect opportunity for the AR 15 platform. Many people proposed expanding the production of the M14 to some other companies, but the idea was eventually scrapped because of the high cost of the M14 to manufacture. It was a great rifle, but it cost a lot to make, its cartridge required more resources, and it was largely considered overkill for fights of 300 yards or less.

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.

There are plenty of misconceptions when it comes to the actual steel used to create an AR 15 barrel. To make things a little less complicated, there are basically 7 different types of barrel steels used to make these barrels, and they can be divided into two categories: carbon and stainless steel. Carbon barrel steels include 4140 steel, 4150 steel, and chromium-molybdenum-vanadium (CMV) which is also called 41V50. The different types of stainless barrels include 410 stainless, 416 stainless, 416r stainless, and 17-4 PH stainless. Most shooters will not want to get into the fine details about the subtle differences between each steel, but the biggest question most people ask is whether they should buy carbon or stainless for their barrels.

Early model handguards for the M16 were triangular in shape, and extended down the length of the barrel to the front sight block. At the time of its inception, this was a huge leap forward in firearm design as the handguard, the buttstock, and the pistol grip were all made of lightweight plastic instead of the traditional wood furniture used in guns like the M1 Garand. This was the beginning of the lightweight and functional handguards that we now know and use today. Handguards make a huge difference when it comes to each individual AR 15, from things such as appearance, weight, and function. While we mentioned that the main function of a handguard is to protect a shooter’s hand from the heat from the barrel while shooting, many accessories can also be added to aid in shooting such as angled back up iron sights, lights, lasers, or forward grips. Taking the time to find and use the right handguard for you and your shooting style is very important to having the perfect AR 15!
