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:
Allows the user to finely tune the weapon's gas flow in order to get maximum performance in diverse shooting conditions as well as optimizing for suppressor use.
Position 1 is normal operation with standard and some military ammunition.
Position 2 is for suppresser use with hotter loads such as military ammunition.
Position 3 is for suppressed use when running standard ammunition.
Introducing the MK118 MOD 2-M Upper, equipped with the revolutionary PWS PicLok™ 15.05” Handguard, showcasing our commitment to innovation and user customization. Crafted with dimensions of 1.7” width and 2.25” height, this handguard strikes an ideal balance between ergonomics and functionality, offering a comfortable and customizable grip for shooters.
The PicLok technology embedded in this handguard allows users to effortlessly mount Picatinny or MLOK accessories, enhancing the rifle's adaptability to individual preferences. We recognize the evolution of rifle rails with the advent of MLOK, and while our handguard embraces this modernization, we acknowledge that Picatinny rails still hold significant advantages. 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, 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.

This choice of material not only ensures exceptional barrel longevity but also maintains accuracy under rigorous shooting conditions.
By opting for 416SS steel, we guarantee that our barrels strike a perfect balance between ruggedness and agility. This robust steel enhances the barrel's lifespan, making it ideal for a wide range of shooting applications. Whether engaged in tactical operations or recreational shooting, shooters can trust in the durability of 416SS steel to withstand the demands of their activities.
Furthermore, our commitment to quality extends beyond material selection, as all barrels are meticulously manufactured in-house. This hands-on approach enables us to maintain precise control over the production process, ensuring that each barrel meets our stringent standards for accuracy, reliability, and overall performance. Ultimately, the combination of 416SS steel and in-house manufacturing exemplifies our unwavering dedication to providing shooters with barrels that offer exceptional performance and durability, establishing them as a trusted choice for discerning firearm enthusiasts.
