PWS UXR: DEEP DIVE
UXR Modified Long-Stroke Piston System
Elevate your shooting experience with the groundbreaking UXR, a marvel of firearm engineering that seamlessly marries revolutionary technology with time-tested excellence. Witness the prowess of the Modified Long Stroke Piston System, a hallmark of reliability and reduced fouling that sets the UXR apart. This innovative platform inherits the legacy of PWS products but is finely tuned and engineered specifically for the UXR, ensuring unparalleled performance and reliability. Typical pistons use a tap-it or short stroke that strikes the carrier and moves it ½”, and relies on the inertia strike to complete the cycle. The UXR uses a modified long stroke where we gave a 1” shove to the carrier completing the camming process and moving the carrier rearward with less recoil impulse.
Why Use the Long-Stroke Piston System?
Opting for a Primary Weapons Systems gas piston system over a traditional Direct Gas Impingement (DI) system on an AR-15 can be motivated by several advantages, particularly in terms of safety, cleanliness, and performance, especially when considering the use of a suppressor. Here are key reasons why you might want to choose a PWS gas piston system:
- Reduced Gas Blowback: In a piston-operated system, like the one offered by PWS, the gas is not directed back into the upper receiver, minimizing gas blowback towards the shooter's face. This design enhances the overall shooting experience, particularly for those who prioritize a cleaner and more comfortable shooting environment.
- Enhanced Reliability: The piston system typically provides enhanced reliability, especially in adverse conditions or when the rifle becomes dirty. Since the operating components are not exposed to the combustion gases to the same extent as in a DI system, there's less chance of fouling affecting the rifle's function. This can be a critical factor for users who require consistent performance in various environments.
- Cooler Operating Temperature: The piston system tends to keep the operating components cooler than a DI system, as the hot gases are vented away from the action. This can contribute to prolonged barrel and component life, reducing wear and potential heat-related issues during extended firing sessions.
- Cleaner Action: PWS gas piston systems contribute to a cleaner overall firearm because the fouling from burnt powder and carbon is not directed into the receiver. This can result in less maintenance and easier cleaning, which is particularly beneficial for users who prefer spending more time shooting than cleaning.
- Suppressor Use: When using a suppressor, a piston system is often preferred due to the reduced gas blowback and overall cleaner operation. Suppressors inherently increase backpressure, and a piston system helps mitigate this effect, providing a more pleasant shooting experience and minimizing the risk of gas and debris reaching the shooter's face.
- Adjustable Gas Systems: Many piston systems, including PWS, come with adjustable gas settings. This feature allows users to fine-tune the gas flow to accommodate different ammunition loads, suppressor usage, or adverse environmental conditions. This level of adaptability is valuable for shooters seeking optimal performance under various circumstances.
