Frequently Asked Questions

What makes the Primary Weapon Systems MK116 Mod 2-M unique compared to other AR-15s?

The MK116 Mod 2-M's primary distinction is its long-stroke piston operating system, a departure from the standard direct impingement. It also features a fully ambidextrous design and proprietary components like its gas system and receiver sets, often manufactured in-house.

How does the PWS long-stroke piston system address carrier tilt?

PWS mitigates carrier tilt through a combination of a 'ski' on the bottom of the carrier and a specially designed receiver extension. This extension has wings that keep the carrier engaged within it, preventing tilting even when the bolt is open.

What are the benefits of the OSS HUXWRK flow-through suppressor on the MK116 Mod 2-M?

The HUXWRK suppressor's flow-through design vents gas forward, significantly reducing gas blowback into the shooter's face and decreasing perceived recoil. This leads to a smoother shooting experience, especially during rapid fire.

What improvements were made in the new forged lower receiver for the PWS MK116 Mod 2-M?

The new forged lower receiver offers increased strength over the previous billet version. Key improvements include a fully ambidextrous bolt catch and release, a larger bolt catch paddle for easier manipulation, and a slightly flared magazine well.
