We take pride in our efficient and stylish design, trying our best to make sure that Yuan and Stern Tri-Regional Engines/Ballistics is your first pick when it comes to anything and everything Errant!

We'd love to share what we're working on, but our elite team of designers, testers, and engineers has deemed this next project simply too good to spoil! Remember, YaSTRE/B does what we do for YOU!
