Desert Tech Quattro Lower receiver with the PSA JAKL upper receiver

Sneak peek at this new project. I'm taking the Desert Teach Quattro lower receiver that has an expanded magazine well that uses a 51 round magazine. Then we are pairing it up with the Palmetto State Armory JAKL upper receiver that uses a buffer less system that allows us to use the JMac folding stock. its going to be epic!!!!
