Semroc Kits

Semroc is now under new ownership and we have new stock of Semroc kits slowly coming in. Limited availability, but it is great to see Semroc back! We will get in what we can when we can as production slowly ramps up and we can get our hands on them. Semroc is now made by rocketry lovers in Dayton, Ohio. Welcome back Semroc!
