The AR9 gun (occasionally hyphenated “AR-9”) is a novel 9mm version of the AR-15.However, this specific 9mm pistol is not merely an AR-15 with a 9mm Parabellum change kit connected. Transformed 5.56/.223 guns use different parts to adjust the factory lower and upper receivers for the 9mm cartridge.
The AR9 weapon instead utilizes a new lower receiver (pertinently named the AR9 lower) and an uncovered AR-15 upper receiver with a 9mm barrel, an AR-15 lower parts kit and buffer system, and a new bolt carrier group. To purchase your AR-9 pistol, reach out to Adventure Survivalist today.

Building an Awesome AR-9 Pistol
The most significant factor of your AR9 body is your barrel. Your AR9’s barrel, unlike typical ole’ black rifles, not only makes your pistol as accurate as possible. The AR9’s barrel length plays a major part in defining whether the rounds you’re shooting go supersonic or stay subsonic.
Do you need a subsonic, close-range AR9 that can be repressed and stay dead-quiet? Or a supersonic, medium-range AR9 that can reach targets at best 100 meters out? Or do you need to aim for someplace in between, somewhere you can play with velocity and hand loads? Let’s break the details down
Barrel length and velocity
To discover the best length of the barrel, we have to explore the ballistics of the 9mm cartridge and we have to learn some science. For a bullet to go supersonic, you need a velocity of over 1,125 feet per second (FPS). Any shot traveling quicker than 1,125 FPS will proclaim that classic “crack and echo” downrange. A bullet traveling under 1,125 FPS won’t break the sound block (it stays subsonic). The only sound made will originate from the gasses exiting the muzzle, which can then be alleviated with a suppressor. Transonic rounds just hardly approach 1,125 FPS. At this speed gray area, the subsonic sound signature gets louder.
The best barrel length
On average, across all nine loads, the best barrel length for 9mm is, aptly, 9 inches. Adding any more barrel for all loads 90 grains up to 147 grains, will only offer an extra 15 FPS, which just isn’t worth the extra flex and weight. Most pistol calibers can be repressed with amazing outcomes. Many shooters who fire suppressed cling to weightier (135- or 147-grain) loads. To keep these subsonic, you require a 5″ or shorter barrel.
The Best Twist Rate
Astonishingly, it is easy to choose the best twist rate for your AR9 pistol. Most handguns and submachine guns chambered in 9mm have by now helped us to know that a 1:10 twist rate is ideal. When Colt initially presented the AR9 platform, this is the twist rate they picked. Shooters have tried different twist rates extending from 1:10 to 1:20.
Most report insignificant variances in shot accuracy and placement. Unlike rifle shots which are fast, long, and require additional help to steady, the 9mm is slower, short, and stubby. Most of its powder is burned instantly, which implies that it reaches ideal velocity faster and steadies more readily with less rifling
