If you want to get more from your AR-15 without a lot of fuss, two parts from Moriarti Armaments stand out: the 762 upper and the ar pistol 7.62. Both use the reliable 7.62×39 cartridge but come in different shapes to fit what you need—whether it’s longer shots or tight spaces.
The 762 upper is a complete top half of a rifle that you can swap onto any standard AR-15 lower. Installation is simple—just remove your old upper and bolt it on. The heart of this setup is a cold-hammer-forged barrel, built to tight specs so you’ll get the same accuracy every time. A mid-length gas system keeps the cycling smooth whether you run light, fast rounds or heavier match-grade ammo. The barrel is threaded so you can add a brake, flash hider, or suppressor, depending on whether you want less recoil, less flash, or both. The handguard features M-LOK slots for lights, grips, or lasers, and the top rail runs the full length so your sights and optics stay in line. Choose barrel lengths from 14.5″ up to 20″ to balance how handy or fast your rifle feels versus how far it shoots.
For shooters who need a smaller, easy-to-move firearm, the ar pistol 7.62 puts the same 7.62×39 cartridge into a pistol form. This kit comes as an 80% lower receiver, which you finish out with your choice of brace, trigger, and grip. The ar pistol 7.62 uses a pistol-length gas system that tames recoil and slows the cycling just enough to extend the life of your parts. Barrel options between 8″ and 10″ give you a compact size without dropping too much velocity—so your rounds still hit with good energy out to normal self-defense ranges. Since it uses standard AR controls, training and handling feel just like your rifle, and the flared mag well plus enlarged bolt catch make reloads quick and snag-free.
Both the 762 upper and ar pistol 7.62 let you tailor your rifle to how you shoot. If you want to stretch your shots out to 200 yards or more, pick the longer barrels of the 762 upper. If you need something that’s easy to carry and maneuver in tight rooms or vehicles, build the ar pistol 7.62. Either way, your magazines, bolts, and lowers stay the same—so you only swap one part.
Customization doesn’t stop there. With the 762 upper, you can pick the gas block style, length of handguard, and barrel profile to save weight or add cooling. Swap in a two-stage trigger or a folding stock to match your style. On the ar pistol 7.62, you can choose different braces—arm, chest, or shoulder—add quick-detach sling mounts, or install compact red-dot sights right on the handguard. Muzzle devices like brakes or compensators help tame recoil even more.
Maintenance is just as straightforward. Both systems break down just like a regular AR—pin out the takedown pins, then clean and inspect your barrel, bolt carrier group, and gas tube. Spare parts for 7.62×39 builds are easy to find and cost less than many other calibers, so you can keep shooting without long delays.
Ready to upgrade? Choose the 762 upper for extended range and smooth shooting, or go with the ar pistol 7.62 for a compact, easy-to-handle package.
