We’re very familiar with the PWS MK111 Pro pistol from Primary Weapons Systems. You should be too. We say that because we gave you all a chance to win a custom pair of them back in June 2020. If you missed the boat, sorry, but take the time to learn about the pistol anyway. Trust us: it’s a good one.

PWS MK111 Pro Details

Primary Weapons Systems does a lot of things right. Perhaps its biggest feat is the PWS long stroke piston system. We’ve spoken about it at length before. But to quote our review of the PWS MK116 MOD 2:

“PWS is unique and has its own niche in the AR marketplace. This is largely in part due to its proprietary long stroke piston design and three-position adjustable gas block. The best way to describe it is that the PWS long stroke piston mimics the piston design of the legendary AKM series of rifles.

“Most, if not all of the AR piston variants offered on the market today, are a short stroke piston design. You will not find any of the dreaded ‘carrier tilt’ or piston slapping in the PWS that have been common in some of its short stroke piston cousins. This is due to the way the long stroke gas piston is designed to move, as a unit rather than several moving parts that are slamming around.”

All of that comes in the PWS MK111 Pro pistol. We got a chance to take it for a spin on the range at the 2020 Athlon Outdoors Rendezvous. Watch the video above to see the pistol out on the range. For even more info, please visit PrimaryWeapons.com.
