After last year’s SHOT Show (2009), DefenseReview published information on the Primary Weapons Systems (PWS) Diablo 7″ (barrel) 5.56x45mm NATO (5.56mm NATO) long-stroke gas piston/op-rod AR (AR-15) SBR/complete upper receiver assembly. Well, this year, at SHOT Show 2010, PWS had a new Diablo SBR on display.

It’s called the PWS Diablo 7.62x39mm (Russian). We have no idea how the new Diablo runs, but we’ve been told that the 5.56mm Diablo runs like gangbusters. That said (or written, in this case), we’ve never fired it, ourselves. It looks cool, though.

Anyway, wanna’ know more about Diablo 7.62x39mm? Ahh…I’ll let PWS tell ya’…

From the PWS website:

Product Details:
Continuing the evolution of the venerable Diablo upper, PWS is proud to offer this fanstic system in 7.62×39. The Diablo is Primary Weapons Systems’ answer to the 7” AR-15/M-16 series upper. Rather than simply bolting on an existing product and calling it revolutionary, PWS stepped back and designed a system from the ground up to work specifically with the extreme pressures of the 7” barrels.

Utilizing the same 7″ barrel as the 5.56, the 7.62×39 version boasts the same stainless steel polygonal bore barrel that is also chrome lined to minimize friction when using steel bullets. A MUR-1 (mil-spec) upper receiver with a billet machined charging handle and low profile quad rails give the most possible room for accessories and rail covers are included for added comfort when shooting.

The Diablo upper utilizes a long stroke piston system for additional dwell time and smooth recoil. The system is rounded out with the new CQB comp from PWS – a comp designed for short barrels that compensates, suppresses flash and directs all the blast forward.

System Features:

– Polygonal Bore, chrome lined, stainless steel barrel and Bolt
– PWS Billet Machined Charging Handle
VLTOR MUR-1 Upper Receiver
– QPQ Coated Internals
Tango Down SCAR Rail Panels
PWS CQB Comp

Simply put, the Diablo upper was designed for those in harm’s way. We built it with quality in mind, instead of price. If your operational requirements call for a small package with a lot of punch, choose the Diablo, by PWS.”
