PWS MK116 MOD 2-M Complete Upper Receiver 5.56 NATO 16.1" – AR-15 Platform

The PWS MK116 MOD 2-M is a complete upper receiver in 5.56 NATO chambering with a 16.1-inch barrel, designed for the AR-15 lower receiver platform. This upper features PWS's long-stroke piston operating system, which eliminates direct gas impingement carbon buildup in the upper receiver and bolt carrier group while reducing heat and fouling transferred to the shooter's face during sustained fire.

The upper receiver is machined from forged 7075-T6 aluminum and finished in black. It includes PWS's free-float handguard with M-LOK attachment points, an adjustable gas block for tuning to different ammunition loads and suppressor use, and a Radian Raptor ambidextrous charging handle. The barrel is cold hammer forged with a 1:8 twist rate. This is a complete upper ready to install on any mil-spec AR-15 lower receiver—no additional components required. Basic armorer knowledge recommended for installation and gas system adjustment.
