MK1 PRO

Introducing the PWS MK1 PRO Line with the renowned PWS long-stroke piston system, tailored specifically for suppressor enthusiasts. If you're in search of a budget-friendly piston system firearm that upholds the exceptional quality synonymous with PWS for over a decade, look no further.

The Long-Stroke Advantage
Inspired by the reliability of the AK rifle, our long-stroke piston system ensures consistent performance. It effectively places combustion forward of the carrier area, reducing wear and tear on critical components. At the heart of the MK1 PRO line is our Long-Stroke piston system, engineered with precision. It offers a 3-setting adjustable gas system, making it ideal for users who employ suppressors. By providing this level of customization, we ensure that your shooting experience is not only smooth but tailored to your preferences.

Adjustable Gas Piston with an Innovative Restrictor System
The MK1 PRO line offers an adjustable gas piston system, allowing you to fine-tune your firearm's performance. Dial down the gas to delay the cycle, pushing more gas forward and mitigating gas blowback to the upper receiver. This not only enhances reliability but also helps manage recoil. Most piston systems feature a vent in the gas block area to release excess pressure, resulting in the dreaded "Piston pop" and increased noise. Our Restrictor system, on the other hand, seals the piston system, significantly reducing noise by 2-3 decibels compared to systems with venting. This not only enhances your shooting experience but also contributes to reduced recoil.

Premium Features
The MK1 PRO line boasts an array of premium features that cater to shooters of all skill levels. Equipped with a free-float MLOK handguard, Radian Raptor charging handle, and an extruded upper receiver with a robust handguard attachment system, this lineup is designed to impress. Whether you're interested in a complete upper or complete firearm (available in both pistol and rifle configurations), the MK1 PRO line has you covered.

Seamless Compatibility
Our commitment to convenience continues with these complete upper receivers, seamlessly fitting into any AR15 lower receiver without the need for additional accessories. It's all about simplifying your shooting experience.

Unmatched Value The MK1 PRO line delivers exceptional value in the piston-driven operating systems market. It combines high-end features with custom components, all backed by our performance expectations and lifetime guarantee, a hallmark of PWS products.

Elevate your shooting experience with the PWS MK1 PRO line, where innovation meets reliability, and value knows no compromise.
