Oem AR 15 parts with 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 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. See extra details at AR 15 Parts.

10.5” 5.56 NATO Pistol Upper Assembly: If you’re still liking the idea of an AR pistol build but don’t like the idea of a super short 7.5” barrel, an obvious solution is the 10.5” 5.56 NATO Pistol Upper Assembly. This is a length where, ballistically, with the right ammo, it could make for a very mean little defensive AR pistol. You’re only adding 3” to the gun, but that length addition, in our opinion, bumps it out of ‘range toy’ category and into an area where you could seriously consider this as a trunk or behind-the-nightstand pistol, depending on your needs. Our 10.5” 5.56 NATO Pistol Upper Assembly has the same features as the 7.5″ 5.56 NATO Pistol Upper Assembly, and paired with one of our bolts, you have a very handy, reliable and practical AR 15 pistol. One caveat: Even at 10.5”, these upper assemblies are still loud. As long as you know what to expect going in…carry on.

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.
