Engineered for Tier 1 close-quarters applications, the PDX measures just 18.75" in overall length, making it the ultimate PDW for confined, urban, or vehicle-based operations. At the heart of the PDX is their patented SCW system-a 4" brace system with an integrated bolt carrier group and interchangeable buffer weights, giving you enhanced recoil control, faster follow-ups, and improved reliability across calibers. Out front, the PDX comes standard with the Maxim HATEBRAKE muzzle booster, installed under the handguard to reduce recoil, decrease flash signature, and redirect blast forward-ideal for use in close-quarters or suppressed.
