The FLUX MP17 changes all of that. They didn’t actually make a new firearm. Instead, they have made a new firearm host. The MP17 takes the fire control module, barrel, and slide of an M17/P320 and places them into the FLUX chassis. Once installed, you’ve now got a PDW that is optics-ready, has a spring-loaded arm brace that deploys with one finger, and has a storage spot in the front of the chassis for storing an extra magazine (don’t dare call it a foregrip).
