Primary Weapons Systems
The Primary Weapons Systems UXR 7.62x39mm Magwell Assembly in black is a precision-engineered component designed for shooters who've invested in the modular UXR XChange platform. This magwell replaces the standard magazine interface, enabling you to run 7.62x39 ammunition on your UXR rifle by pairing it with the appropriate barrel and bolt for that caliber. It's part of PWS's approach to true caliber conversion—swap the barrel, bolt, and magwell, and you've got a completely different rifle configuration without needing multiple complete guns.
The ambidextrous design accommodates both right and left-handed shooters, ensuring that magazine insertion and charging handle ergonomics work naturally regardless of your dominant hand. This matters if you're building a rifle for yourself or equipping a platform intended for mixed-handed use. The magwell is finished in black and built to the precision tolerances you'd expect from a dedicated PWS component, not an aftermarket band-aid.
If you're already running the UXR XChange system—or planning to—the 7.62x39mm magwell opens up a practical intermediate cartridge option for hunting, training, or lower-cost range work. Compatibility is straightforward: this assembly works within the UXR ecosystem as PWS designed it. Installation and function depend on having the matching barrel and bolt for 7.62x39; the magwell alone doesn't make a complete conversion kit, but it's the critical piece that ties everything together.
| Caliber | 7.62x39mm |
| Platform | PWS UXR XChange |
| Handed | Ambidextrous |
| Finish | Black |
This magwell assembly is designed specifically for the PWS UXR XChange platform and integrates with that system. It is not a direct fit for standard AR-pattern rifles.
The magwell is one component of a complete 7.62x39 conversion. You'll also need the matching barrel and bolt for that caliber. The magwell handles magazine compatibility; the barrel and bolt handle the actual cartridge chambering and function.
Yes, the ambidextrous design accommodates both right and left-handed shooters without additional modification.
This magwell assembly is available in black.
