Getting 7.62x39 to be reliable in an SBR has been a challenge … until now. The Maxim Defense PDX is one of the coolest guns to hit the market recently, and we got a chance to take it for a test drive at F.I.R.E. Expo in Florida this year. This little gun features the firepower of an AK while reaching just 18.75 inches in overall length. It’s designed for close-quarters combat and first response, with the small size making it easy to maneuver in tight spaces. It is offered in three calibers: 5.56 NATO, 300 BLK, and 7.62x39.
