PUSH VS PUNCH
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.

ADJUSTABLE GAS BLOCK
The 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.
 
QPQ ISONITED® BARRELS
Utilizing only the highest quality chromoly barrel blanks, PWS .223 and 300BLK MK1 barrels are turned in house then Isonite QPQ® treated for increased surface hardness and corrosion resistance.

PROFILE
Our barrels are designed with a heavier profile that increases longevity and accuracy, creating a balance between weight savings and sustained durability.
 
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.

MASS
Features an 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.

CONTACT POINTS
Gaps and channels between skid pads allow for fewer points of contact. This results in less friction and keeps debris from interfering with function.

BOLT
The PWS bolt system is Nickel Teflon coated and optimized for the .223 wylde chamber. It features a small assist spring for system assembly.
