When it comes to power and accuracy, the Primary Weapons Systems MK218 is a long-range rifle that lives up to its promise.

In this review, we’ll take a closer look at all that makes the MK218 such an attractive choice for those seeking an accurate and reliable long-range rifle.
Design
The PWS MK218 utilizes a patented long-stroke piston system to help ensure consistent and reliable operation. The long-stroke piston design helps to keep the action very clean, and ensures that the rifle is able to function well in any condition. The long-stroke piston system also helps to reduce barrel and receiver heat, further improving accuracy and reliability.
The MK218 also integrates an adjustable gas system which allows shooters to fine-tune the rifle’s operation to their individual shooting style and preferences. The adjustable gas system also helps to decrease the amount of felt recoil, making the rifle more comfortable to shoot.
The Mk218’s upper and lower receivers are made from billet aluminum, and the rifle is available in five different lengths — ranging from 16” to 24” — which allows shooters to customize the rifle to their specific needs and preferences. Additionally, the Mk218 is designed with ambidextrous features, including an ambidextrous safety switch, magazine release, and bolt catch, which makes it an ideal rifle for left-handed shooters.
Ergonomics
The Primary Weapons System MK218 is designed with an adjustable stock which allows shooters to adjust the length of pull and comb height to help ensure a proper fit. In addition, the MK218 is compatible with most popular aftermarket components, such as rail systems, pistol grips, stocks, and more, which gives shooters the ability to further customize the rifle to their specific needs and preferences.
The Mk218 also features a free-floating KeyMod handguard which allows for the attachment of various accessories, such as bipods, laser sights, etc. Additionally, the Keymod handguard helps to reduce the overall weight of the rifle, and provides a secure, ergonomic grip for the shooter.
Performance
The Primary Weapons System MK218 is designed to be a highly accurate and reliable long-range rifle. The rifle is accurate out to 800 yards when using match-grade ammunition, and is capable of shooting sub-MOA groups. Additionally, the MK218 features a mild-recoil impulse, which helps to reduce shooter fatigue when shooting for long periods of time.
The MK218 is chambered in 6.5 Creedmoor, which is the preferred round of many long-range shooters due to its superior accuracy and energy transfer. The MK218 is also capable of reliably feeding from a variety of magazine capacities, including 5-, 10-, 15-, and 20-round magazines. As such, this rifle is well-suited for target shooting, hunting, and tactical/takedown situations.
