Primary Weapons Systems
The PWS UXR Magwell in 7.62×39 is a modular magwell assembly designed for shooters building or customizing rifles chambered in this popular intermediate cartridge. Primary Weapons Systems engineered this component around the UXR XChange system, which lets you swap calibers without a complete rifle rebuild—change the barrel, magwell, and bolt, and you've adapted to a different cartridge. The ambidextrous magwell design works for both right and left-handed shooters and accommodates the magazine type specific to 7.62×39, making it a key part of a truly adaptable platform whether you're setting up a hunting rifle, tactical carbine, or range gun.
This magwell represents the modular philosophy at the heart of the XChange ecosystem. Instead of owning multiple rifles or permanent modifications, you maintain one lower receiver and swap upper components as your needs change. The ambidextrous layout means lefties get the same functional access as righties—no compromise, no dedicated left-hand builds required. Magazine changes are swift and intuitive, and the magwell is engineered to the same exacting standards PWS applies across their catalog.
If you're already invested in the UXR platform or considering it as your next rifle project, this magwell unlocks the full potential of 7.62×39 in a modular setup. It's a straightforward, high-quality component that does exactly what it's designed to do: feed reliably and play seamlessly with the rest of the system.
The UXR XChange is Primary Weapons Systems' modular rifle platform that allows you to change calibers and barrel lengths by swapping the barrel, magwell, and bolt assembly. This magwell is the 7.62×39 component of that system.
Yes. The UXR Magwell is ambidextrous, designed to work intuitively for both right and left-handed shooters without any sacrifice in function or ergonomics.
This magwell is designed for 7.62×39 caliber magazines compatible with the UXR platform. Always verify magazine compatibility with your specific rifle configuration.
To convert to a different caliber, you'll need to swap the barrel, this magwell, and the bolt assembly. The lower receiver remains the same, which is where the UXR system saves you time and money.
