The Maxim Defense PDX AR Pistol Kit comes with everything you need except lower to build out your own version while having most of the parts shipped right to your door. This PDX AR-15 Pistol Kit is chambered in 5.56 and is compatible with standard AR style lower receivers. The PDX 5.56 features a 5.5” barrel while still being a traditional AR style gas system and retaining all the reliability. The Maxim Hatebrake muzzle brake directs gas and concussion down range away from the shooter and decreases the flash signature making it more bearable for the user when used in close quarters. If you are looking to build the ultimate PDW, check out the Maxim Defense 5.56 PDX AR-15 Pistol Kit.
