The PTS KWA Bolt Carrier Set is a complete drop-in Steel Bolt Carrier Group with Nozzle. Like the original stock bolt carrier, it is made out of steel for durability and recoil mass. However, this PTS bolt carrier boasts angular flat cut surfaces for both a modernized appearance and for weight optimization.  With its lower mass, the PTS bolt carrier cycles faster,reduces friction and drag, and reduces the consumption of gas thus making the gun perform far more efficiently.
