I traded a few high end handguns a while back for a TROS PS90 SBR. It was on a form 4 and arrived at my dealer a few days ago. I finally put my biscuit grabbers on it and fell in love! I am installing a KAC QD flash hider for my 5.56 suppressor and I'll be good to go. I got to thinking, "would I have bought a PS90 if I didn't trade for it?" My initial response is no because this weapon BEGS to be a SBR. I'm not knocking the PS90 but the weapon true to its form is a SBR.
