Perfect Aero Precision AR 15 upper 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.
Keymod gets its name from the slots in the system that look like keyholes. To use a keymod handguard, all you have to do is place the mounting lug in the keyhole and slide it to the narrower end to tighten your attachment securely to the firearm. It is extremely easy to use and nowhere near as heavy or bulky as the picatinny system. Overall, this system is probably the most familiar and the longest running system of them all. If the additional weight and bulk of the picatinny platform doesn’t bother you, then there is nothing wrong with this system and it is a tried and true design. You will be pretty much guaranteed mounting for just about any accessory and won’t need to spend extra for any parts. This is probably also the cheapest option out of all of them as well.
Cut rifled barrels have long been considered the standard for the AR 15. It is by far the most popular and still to this day one of the most cost-effective ways to create barrels. A cut rifled barrel is created just like the name says: a barrel blank is inserted into a rifling machine, which resembles a large lathe. The machine then pushes a single cutter attached to a long rod through the rough rifle bore, carving out each groove of the rifling. This entire process can be very time consuming, but given the right technique and equipment, produces the most accurate AR 15 barrels that you can find. Discover more info on AR 15 Parts.

For most handguards, the two most commonly used materials are polymer and aluminum. Both of these materials are very durable, and aluminum will usually going to be the stronger of the two. Aluminum can, however, emit a little more heat during an extended shooting session than a polymer handguard. Aluminum is much more resistant to heat, although it will heat up itself and can be hot under extreme conditions. If you do a lot of high volume shooting, aluminum is a great option for you. Polymer handguards will usually have a heat shield constructed of either steel or aluminum that will separate the actual polymer from the barrel. This helps dissipate the heat generated from the barrel, and there are also polymer handguards that will have a steel or aluminum framework to lighten them up and provide structural durability. Polymer does, however, have a lower melting point than aluminum. While it is super rare, under continuous and extreme firing, the heat from your barrel could warp or even melt the polymer handguard. Polymer does, however, provide a little more impact resistance than aluminum.
