THE PWS LONG STROKE PISTON
The PWS long-stroke piston system combines the agility of the AR-15 with the reliability of the AK-47 into a sleek and efficient design.
ADJUSTABLE GAS BLOCK
Our four position adjustable gas block restricts gasses, rather than venting them from the side. This allows the unused gas to exit from the front of the gun, rather than the sides of the gas block, resulting in a more quiet operation..
SMOOTH RECOIL IMPULSE
By utilizing a one piece design, the PWS piston system creates a purely gas to metal operation, rather than metal on metal contact that you may see in other designs. That, in addition to the longer dwell time from the increased mass in the Enhanced Bolt Carrier, creates a pushing action rather than a punch. This results in dramatically reduced felt recoil.
QPQ ISONITED BARRELS
Utilizing only the highest quality chromoly barrel blanks, MK2 barrels are turned in house then Isonite QPQ treated for hardness and corrosion resistance.
Our barrels are designed with a heavier profile that increases longevity and accuracy, creating a balance between weight savings and sustained durability.
TWIST & CHAMBER
MK2 barrels are button rifled with a 1:10 twist, and are chambered in .308 WIN
BOLT CARRIER GROUP
PWS bolt carrier groups are machined from tool steel at strict tolerances, then nickel-Teflon coated for durability and to reduce friction.
PWS engineers increased carrier mass to extend dwell time and delay unlock. As a result the PWS bolt carrier group allows chamber pressure to be greatly reduced for easier extraction.
MINIMIZED CONTACT POINTS
Gaps and channels between skid pads allow for fewer points of contact. This results in less friction and keeps debris from interferring with function.
The PWS bolt system is Nickel Teflon coated and optimized for the .308 Win chamber.
PWS engineers designed a handguard which is ergonomic as well as durable. Featuring the KeyMod interface, the MK2 series handguard eliminates unnecessary weight and allows for a wide range of accessory placement.
Handguards are extruded, then machined from aircraft grade 6061 aluminum.
PICATINNY TOP RAIL
Impact extruded, then machined from aircraft grade 6061 aluminum, every handguard comes standard with a full-length Picatinny top rail and two 2 inch Picatinny sections.
Integral sling swivel attachment points round out the front and back of the handguard.
The KeyMod Interface System was developed for multiple accessory compatibility without the need for Picatinny rails surrounding your handguard. This improved design enhanced the rail’s comfort and functionality without sacrificing strength and durability.
UPPER & LOWER FORGINGS
Understanding the importance of an ultra-reliable package that is as light as possible, mil-spec 7075 aluminum forgings are used for the upper and lower receivers. Each upper and lower are meticulously CNC-machined for perfect fit and function.
After machining and blasting, all aluminum parts are Hardcoat Annodized at Type III Mil-Spec, for corrosion and wear resistance.
All MK2 rifles ship with durable Magpul furniture.
ENHANCED BUFFER TUBE
Machined from one piece of 6061 aircraft-grade aluminum, PWS engineers were able to pack more features into the PWS buffer tube.
GOODBYE CASTLE NUT
Eliminating the castle nut, the PWS EBT’s unique indexing screw & plate system ensures secure fit and precise alignment.
Features a lip that extends into the receiver to support the back of the carrier to compensate for carrier tilt.
Unlike aftermarket items, PWS EBT QD attachments are machined directly into the aluminum for durability and weight savings.
MK1 buffer tubes are fluted, creating channels for debris, and feature four drain holes on the bottom to allow for faster water drainage.
Low contact points allow debris to fall into channels, while the Nickel Teflon coating keeps carbon from sticking. PWS machinists engrave the PWS logo directly into the 4140 carbon steel.
