The Maxim PDX was developed from the SOCOM PDW solicitation and was designed to withstand the rigors of the Tier 1 community. With its ultra compact 5.5″ barrel, the PDX dominates at close quarters applications. At only 18.75″ in length it delivers rifle cartridge firepower in a subcompact platform.


Outfitted with the new SCW pistol brace which cuts down the length to a mere 4″. An integrated BCG with interchangeable buffer weights allows the user to fine tune the weapon system. The HATEBRAKE muzzle booster allows for improved performance in short barreled applications while reducing recoil, flash signature and sends concussion forward.
