The PWS UXR Magwell Assembly is the medium-frame piece that lets your User XChange Rifle run standard AR-15 style magazines. If you've got a UXR and you want to shoot .223 Wylde or 300 Blackout, this is the magwell that gets you there. It's built for the XChange platform, so it drops right into the ecosystem without any drama or extra fitting.
What makes the UXR so interesting is the whole concept behind it. The upper receiver is the serialized part, and you change calibers by swapping just three components: the barrel, the bolt head, and the magazine well. This magwell is that third piece for the small-frame chamberings. It's outwardly sized to fit the AR-10 footprint of the rifle but built internally to accept STANAG magazines, so your standard AR-15 mags rock right in without slop.
Southpaws and righties both get treated equally here. The magwell is designed for ambidextrous use, so no matter which hand runs your reloads, the geometry works the same. It's a polymer assembly that keeps weight down while holding up to the kind of high-round-count sessions PWS builds its reputation on.
Think of this magwell as one leg of a three-legged stool. Pair it with the matching .223 Wylde or 300 BLK barrel and bolt head, and you've got a complete caliber configuration on a single lower. Because the UXR uses a universal recoil spring and bolt carrier, you're not fighting the gas system every time you switch. The parts are marked with a dot system to keep the right pieces grouped together, which takes the guesswork out of a swap.
This is the AR-15 medium-frame magwell in black, matched to the .223 Wylde chambering. It's a smart add for anyone building out a UXR into a true multi-caliber rig without buying a whole second gun.
It's the magazine well that lets your UXR accept AR-15 pattern magazines for .223 Wylde and 300 Blackout. It's one of three parts (magwell, barrel, and bolt head) you swap to change calibers on the same serialized upper. Think of it as the piece that tells your rifle which magazine family to feed from.
Yes. Although the magwell is outwardly sized to the AR-10 footprint of the rifle, it's filled in internally to accept STANAG magazines, so your standard AR-15 mags drop right in. That means you can run the mags you already own for the .223 Wylde and 300 BLK chamberings.
No, this listing is the magwell assembly only. To complete a caliber configuration you'll also need the matching UXR barrel and bolt head for .223 Wylde or 300 BLK. PWS marks its XChange parts with a dot system so the right pieces stay grouped together.
It is. The assembly is designed to be ambidextrous, so the layout and reload geometry work the same whether you're right or left handed. Nobody gets shortchanged based on which hand runs the gun.
