About the real Diablo:Produced by PWS Primary Weapon Systems
The Diablo Upper 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.

We started with the barrel and after careful research decided on a 7” (not 7.5”) stainless steel polygonal bore barrel with a 1:8 twist.  A match bolt carrier assembly is housed inside of a MUR-1 (mil-spec) upper receiver with a billet machined charging handle.  Low profile quad rails give the most possible room for accessories and XTM rail covers.

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.
