Description
The PDX redefined compact firepower in terms of size, durability, and accuracy. The next size up in the MDX family is the 508. With the same heart and soul of the proven PDX, the 508 features an 8.5″ barrel, ideal for when maximum concealment and compactness are important, but not as crucial.
The 8.5″ barrel delivers higher velocities while the SCW system plays a key role in the compact size. The SCW stock or brace adds a mere 4″ to the end of the receiver with a full extension of 8.75″, providing complete comfort to the operator. Our proprietary bolt carrier group and buffer & spring options ensure extreme durability and smooth cycling.
Our MDX series firearms are also equipped with the Maxim’s HATEBRAKE muzzle booster. This patent-pending device significantly reduces recoil, decreases the flash signature, pushes gasses and concussion waves downrange away from the operator, and improves overall performance.Maxim Defense
