Maxim Defense PDX Complete Upper Kit For AR15 – Black | 300BLK | 5.5″ Barrel | Hate Brake | SCW PDW Brace

At the heart of the PDX™ KIT is our newly developed Maxim SCW™ PDW brace system. This patent-pending design cuts down the length of the brace to 4” and offers an integrated BCG with interchangeable buffer weights to give you the flexibility to maximize performance and versatility without sacrificing functionality or form. The PDX™ KIT is also equipped with newly invented Maxim HATEBRAKE™ Muzzle Booster. This patent-pending device significantly reduces recoil, decreases the flash signature, pushes gasses and concussion waves downrange away from the operator improving overall execution in short barrel pistols and rifles. The PDX Kit uses a Direct Impingement system. The PDX Kit comes with everything you need to turn your lower receiver into a Maxim Defense PDX.
