This review of the Primary Weapon Systems Mk111 Pro piston AR pistol highlights its "wonderfully different" design. Key takeaways include the benefits of a piston system for cleaner and cooler operation, the unique pistol storage device (legally distinct from a brace/stock), and its controllable recoil impulse despite the short barrel. The adjustable gas block is noted, though not tested with suppressors in this review.

This video details an accuracy test of the Primary Weapon Systems MK 111 PRO piston AR pistol at 100 yards. The test involved shooting five different ammunition loads, ranging from 35 to 77 grains, to assess the pistol's ability to stabilize various bullet weights and the impact of ammunition quality on accuracy. The results indicate the 11-inch barrel can achieve useful accuracy, with heavier, match-grade ammunition performing significantly better.
