What about this one? 100% American made striker fired semi-automatic VSS available in 300 BLK, 5.56x45, and 7.62x39 with a 16" barrel. Sounds like it could get a restricted classification, or NR with 18.5" barrel if they ever made one. But I'd be down for a restricted one. They've made some changes to the design and its supposed to use a standard AR-15 bolt which is pretty cool.
