High quality Aero Precision AR 15 parts? 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.

Once you decide on the type of handguard you want, what about the length? Luckily most handguards, regardless of design or material, are available in multiple different lengths. They come in a selection of standard lengths that will correspond to standard lengths made for the barrel and gas system. Figure out what barrel length and gas system you have or will be running, and make sure you get a handguard that will perform properly with the specs you need. While this test did not turn out very great for keymod, it does not mean that it is a bad system. Both mounting systems work great and are very popular and available. Whichever system you use, rest assured that it will successfully allow you to add whatever accessories you want to your AR-15. If this system has any disadvantages, it is that it can sometimes be a little tricky to properly align any attachments that you are installing. M-LOK is quickly gaining more and more popularity every year, as more and more companies are making accessories using this mounting system.

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.

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.
