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 MK107 MOD 2-M Upper, equipped with the revolutionary PWS PicLok™ 6.9” 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 MK107 MOD 2-M Upper 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.
The use of 41V50 steel in the construction of barrels, such as the 7.75" barrel featured in this rifle, highlights PWS's commitment to providing top-notch performance. 41V50 is a high-quality, chromium-molybdenum-vanadium alloy steel known for its exceptional strength, toughness, and resistance to wear and heat. Our choice of this premium steel demonstrates their dedication to producing barrels that can withstand rigorous use while maintaining accuracy.
By selecting 41V50 steel, we ensure that our barrels offer a harmonious balance between durability and maneuverability. This steel's robust nature contributes to the barrel's longevity, making it well-suited for various shooting scenarios. Whether engaged in tactical operations or recreational shooting, users can rely on the durability of the 41V50 steel to withstand the demands of their chosen activities.
It's worth noting that our commitment to quality extends beyond material selection. The fact that all barrels are manufactured in-house speaks to their meticulous control over the production process.

Elevate your shooting experience with the dual-functional PWS CQB Compensator, designed for both recoil reduction and flash suppression. This top-tier compensator redirects sound forward, making it ideal for close-quarters combat situations, such as law enforcement and military units operating indoors and at short ranges. Gain popularity for use on short-barreled rifles, this compensator excels at mitigating sound and blast while improving overall weapon control. The patented design features unique port designs that effectively channel flash away from optics and the line of sight, ensuring a clear view and reducing overpressure. Expertly mounted for optimal performance, the CQB Compensator is a key component in the rifle's overall recoil management system, facilitating quick follow-up shots and providing improved shooter control. Opting for the PWS CQB Compensator delivers the best of both worlds—enhanced recoil management and effective flash suppression—making it a preferred choice among discerning AR15 enthusiasts.
Which muzzle device is the best for you?
Compensator: A compensator is designed to mitigate recoil and muzzle rise, enhancing overall shooter control. It achieves this by directing gases in specific directions to counteract the natural upward movement of the firearm during firing. While compensators can have secondary functions, such as flash suppression, their primary goal is recoil management. The PWS FSC 556 compensator, for example, excels in reducing recoil and features unique port designs to keep flash away from optics and the line of sight.
Flash Hider: A flash hider is primarily designed to minimize the visible muzzle flash that occurs during firing. It disperses the burning gases produced by the ignited gunpowder, reducing the intensity of the flash. Flash hiders are valuable for maintaining shooter visibility in low-light conditions and for preventing temporary visual impairment that can occur with larger-caliber firearms. However, they don't provide significant recoil reduction.
Muzzle Brake: A muzzle brake, like a compensator, is focused on recoil reduction and muzzle rise control. It achieves this by redirecting gases to counteract the firearm's natural movement during firing. Muzzle brakes are effective in reducing felt recoil but may produce more noticeable side blast and increased noise compared to compensators. They typically do not offer flash suppression as a primary feature.
