Get Into a Piston-Driven AR At a Price You Can Afford
Fans of the AR-15 have long admired the piston-driven options on the market, since these designs don't dump fouling and muzzle gases back into the receiver. This makes the guns run a bit cleaner, but consumers have often paid premium prices for the design. Enter the Primary Weapons MK-111 Pro Pistol.

Chambered in .223 Wylde, the PWS MK-111 Pro Pistol is built with a long-stroke gas-piston system, which makes the platform affordable while still providing the benefits of a piston-driven AR. The long-stroke system offers three different adjustable settings, allowing users to fine-tune its use with suppressors and different ammunition loads. The barrel and gas system are surrounded by a free-float handguard with M-LOK attachment slots.

- Barrel length: 11.85 inches
- Overall length: 28-31.5 inches
- Ships with one 30-round magazine
- All-black finish

For those looking to get the benefits of the long-stroke system on the MK-111 Pro Pistol without buying an entirely new firearm, the lineup is also available as a standalone upper that fits onto any standard AR-15 receiver. Other features found in the unit include a Radian Raptor charging handle, as well as a pistol-buffer tube for today's popular, non-NFA stabilizing braces.

I own this pistol and I love it, no issues with the 6061 but then again I don't "operate" with my guns either. I agree with you on the sba3, bought one and had it installed before I even left the gunshop.
