Frequently Asked Questions

What makes the PWS Mk1 Mod 2 'Diablo' unique compared to a standard AR-15?

The PWS Diablo's primary distinction is its AK-inspired long-stroke gas piston system, integrated into an AR-15 platform. This design enhances reliability and offers smoother operation. It also features proprietary components like a fluted buffer tube and an internal tension plunger for a tighter receiver fit.

What are the caliber options for the PWS Mk1 Mod 2 series?

The PWS Mk1 Mod 2 series is available in multiple calibers. The Mk107 'Diablo' features a 7.75-inch barrel and is offered in 5.56 NATO or .223 Wylde. Other models in the series, like the Mk109, are available in .300 Blackout, and variants exist for 7.62x39mm.

How does the PWS Diablo's gas system differ from other AR-15s?

Unlike most AR-15s that use a direct impingement or short-stroke piston system, the PWS Diablo employs a long-stroke gas piston system. This system is adjustable with three positions and features an enlarged gas block volume to optimize dwell time, resulting in lower carrier speeds and improved cycling.

What materials and coatings are used in the PWS Diablo's bolt carrier group?

The bolt carrier group (BCG) in the PWS Diablo is constructed from durable S7 tool steel. It is further enhanced with a Nickel Teflon 'LIFE' coating, which provides excellent wear resistance, lubricity, and makes the BCG easier to clean.
