The 7.62x39mm cartridge is most closely associated with the AK-47 family of firearms. In the United States, this caliber is also available for AR-15s. Traditionally, 7.62x39mm ammunition is less expensive than 5.56mm NATO or .223 Remington, making it cheaper to shoot in high volumes.

Typically, converting your AR to 7.62x39mm requires nothing more than a new barrel, BCG, and magazine. However, you may find it more convenient to have an entire dedicated upper receiver, as it is much faster to swap out than partially stripping your rifle and replacing the requisite parts.

1. Ghost Firearms Vital 7.62 Upper Receiver

ghost firearms vital 7.62 upper receiver

Ghost Firearms is a parts manufacturer specialized in AR-15s and AR-10s, offering a range of barreled upper receivers, lower receivers, and build kits in various calibers.

The Ghost Firearms Vital 7.62 Upper is part of the company’s AR-15 upper receiver line. This specific model is chambered in 7.62x39mm and is available with either a 10.5” or a 16” barrel. The 10.5” barrel is an ideal candidate for an AR pistol, braced pistol build, or an SBR, whereas the 16” barrel is an excellent choice for a standard carbine.

Regardless of the barrel length you choose, you will get a high-quality barrel forged from 4150 chrome-molybdenum steel, granting your AR-15 build accuracy and long-lasting performance.

The barrel comes out of the box fitted with a removable A2-style birdcage flash hider. If you want to upgrade your barrel with a muzzle brake or a suppressor, this barrel features a ⅝x24” thread pitch, as is typical for .30-caliber AR platforms.

The 16” model is what Ghost Firearms refers to as a Light HBAR, possessing a barrel profile similar to a traditional heavy barrel but with a slightly reduced overall weight. This profile helps keep your firearm weight down, making it more convenient to carry.

The railed upper receiver is mated to an M-LOK handguard, extending the top rail length and offering you M-LOK attachment points on the 3, 6, and 9-o’clock positions.

Pair this upper receiver with the 7.62x39mm BCG and charging handle of your choosing, and it will be ready to install on any lower receiver.

This assembly features a 4150 chrome-moly-vanadium (CMV) steel barrel with Melonite finish, conforming to military specifications and full-auto rated. This alloy gives your barrel superior durability and heat resistance compared to standard chrome-moly models.

4. Faxon Firearms ARAK-21 Upper Receiver

faxon firearms arak-21 upper receiver

Faxon Firearms is a well-known firearms manufacturer, most famous for the ARAK-21 XRS, an innovative firearm combining the controls, ergonomics, and lower receiver of an AR-15 with an upper receiver and a gas piston operating system resembling the one used in the AK platform.

This product is the ARAK-21 upper receiver with a 7.62x39mm barrel. Installing this product on any mil-spec AR-15 lower will convert it to an ARAK-21.

The core of the ARAK-21 system is the long-stroke gas piston system with an adjustable, four-position gas system. The available settings include three gas flow levels, ideal for adjusting your rifle to dirty ammunition, suppressor usage, or adverse conditions.

You can also shut off the gas system entirely, disabling the semi-automatic action and turning your rifle into a straight-pull bolt action.

The 16” barrel uses high-durability 4150 CMV GBQ steel, heat-treated, and coated in a QPQ nitride finish. Like most .30 caliber AR-15 barrels on the market, the ARAK-21 barrel features a ⅝x24” thread pitch. It ships with a proprietary flash hider.

Due to the gas piston operating system, you don’t need to install an AR-15 charging handle or BCG. As this design does not feature a buffer tube, you can install it on a lower receiver compatible with folding stocks without issues.

The entire upper receiver assembly is machined from a 6061-T6 aircraft-grade aluminum billet. It features a one-piece design, a full-length Picatinny top rail, and three additional Picatinny rails, making it a true quad-rail handguard.

This upper is also fully ambidextrous, featuring an ambidextrous charging handle and a proprietary 8-lug bolt with a reversible cam pin.

  • Model: ARAK-21 Upper Receiver 7.62×39

The upper receiver and handguard employ standard 7075-T6 aircraft-grade aluminum billet in their construction, coated with a hard-coat anodized finish.
