Trinity Force AR 15 upper 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.
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.

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.

Early model handguards for the M16 were triangular in shape, and extended down the length of the barrel to the front sight block. At the time of its inception, this was a huge leap forward in firearm design as the handguard, the buttstock, and the pistol grip were all made of lightweight plastic instead of the traditional wood furniture used in guns like the M1 Garand. This was the beginning of the lightweight and functional handguards that we now know and use today. Handguards make a huge difference when it comes to each individual AR 15, from things such as appearance, weight, and function. While we mentioned that the main function of a handguard is to protect a shooter’s hand from the heat from the barrel while shooting, many accessories can also be added to aid in shooting such as angled back up iron sights, lights, lasers, or forward grips. Taking the time to find and use the right handguard for you and your shooting style is very important to having the perfect AR 15!
