Oem AR 15 lower 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 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.
Cold hammer forged barrels are some of the most popular AR 15 barrels out there, and for good reason. These barrels are generally super durable and extremely accurate. Because of this, they are often highly favored among defense and military personnel. These barrels are made by taking a large-sized barrel blank and forcing a tungsten carbide mandrel through the unfinished bore. The mandrel has the shape and cut of the rifling on it, and once in place, the blank is pounded into its final shape by very large hammers. See even more information at ar 15 parts.
This 7.5” length pistol upper assembly makes for a very fun but boisterous range gun. We run our little AR pistol with a black nitride bolt carrier group and have put just over three thousand rounds thru our personal T&E gun without a hiccup. it’s a tiny package that runs and runs, and is about as much fun as you can have with a small AR pistol. I would stress that, in our experience, this is an upper assembly I’d go with for fun above practicality. I’d also warn you that 5.56 out of a 7.5” upper assembly is quite loud. Loud may even be an understatement. I’m fairly certain, that given a choice, I’d NOT want my home defense AR sporting a 7.5” barrel. That said, the next step up is a lot more practical in that regard.
The other type of handguards that are the most popular are free-float handguard options. Almost all of these are made out of aluminum instead of polymer. They generally also cost a little more, but they do offer a big advantage over drop-in handguards in that they do not contact the forward portion of the barrel, which can be a major benefit to the rifle’s accuracy. Free-float handguards usually come in one solid piece that will slide around the barrel and are generally attached with some sort of barrel nut. These types of handguards are usually equipped with different types of mounting systems and accessories, as well as being available in different sizes, lengths, and styles. Free float handguards will also sometimes require more effort and time to install, and some will even require the use of special tools or equipment as well. Free float handguards are quickly becoming some of the most popular handguards on in the market today.
