PWS MK118 MOD 2-M UPPER

PWS Long-Stroke Piston System

The MK118 MOD 2-M Upper operates on the highly acclaimed PWS Long Stroke Piston System, renowned for its reliability and reduced fouling. The inclusion of a 3-setting Adjustable Gas System allows users to fine-tune gas flow, ensuring optimal performance in diverse shooting conditions. This innovative system not only enhances reliability but also provides adaptability to various ammunition types and environmental factors.

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.

At PWS, we pride ourselves on providing a unique blend of innovation and tradition. While MLOK offers a streamlined and lightweight solution, the robustness and versatility of Picatinny rails are unmatched. Our handguard design combines the best of both worlds, ensuring our consumers benefit from the adaptability of MLOK alongside the time-tested advantages of Picatinny rails, setting PWS apart in offering a truly comprehensive and versatile rail system.

Chambered in 223 Wylde

Chambered in .223 Wylde, the MK118 MOD 2-M is meticulously designed to offer outstanding accuracy and reliability. This caliber choice allows shooters to seamlessly use both .223 Remington and 5.56mm NATO ammunition, providing versatility without compromising on performance.

Why 223 Wylde?

Choosing a rifle chambered in .223 Wylde offers the best of both worlds for consumers seeking versatility and optimal performance. Developed by Bill Wylde, this chamber design seamlessly accommodates both .223 Remington and 5.56mm NATO ammunition, providing users with a broader range of options. The .223 Wylde chamber resembles the .223 Remington externally but incorporates a slightly longer throat to handle the higher pressures associated with 5.56mm NATO rounds. This design not only ensures compatibility with both cartridge types but also enhances accuracy by accommodating longer, heavier bullets commonly used for precision shooting. In essence, opting for a rifle with a .223 Wylde chamber means enjoying the flexibility to use different types of ammunition without compromising on accuracy, making it an ideal choice for shooters looking for a versatile and high-performing firearm.
