PWS - Primary Weapons Systems Mk116 Mod 2 Complete Upper w/ Mod 2 FSC556 Muzzle Device


The Mk1 Mod 2 Series by PWS is the latest iteration on their piston driven uppers and firearms.  The Mk116u Mod 2 is a 16" barrel with an attached FSC556 Mod 2.

The Mod 2 receiver is PWS' custom forged upper.  Forging produces a stronger piece than billet manufacturing because the internal grain of the metal follows the general shape of the part, making the Mod 2 both lighter AND stronger than a billet counterpart. PWS further improves the Mod 2 with their PICMOD technology. A unique hybrid between Keymod and Picatinny, PICMOD gives you the most flexible mounting options where it is present at the end of the rail.

An adjustable gas block offers three positions which can be adjusted easily through the cut-out in their proprietary rail system.  With this system, you can have a spare upper for any AR-15 lower, that has the benefits of an adjustable piston for use with suppressors.
