Black Rifle Depot AR 15 lower parts by blackrifledepot.com? 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.

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. Read additional info on AR 15 Parts.

Depending on the laws in your state and your willingness to do extra paperwork, a Short Barreled Rifle (SBR) can make for a very handy package. Obviously, NFA rules do apply. You’ll most certainly need to research that. That said, instead of an SBR, many builders today are opting to build AR pistols. If you have decided to go that AR pistol route, then Black Rifle Depot offers a few different short 5.56 AR 15 upper assemblies that are both affordable and reliable. Our shortest option is a 7.5″ 5.56 NATO Pistol Upper Assembly that features a 4150CMV steel barrel, a 7″ M-LOK handguard an A2 flash hider, 7075-T6 Forged Upper Receiver, a forward assist and dust cover, and our lifetime warranty from 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.
