Hmmm, FAC only. Only just looked it up on the titnterwep after reading your post. I think it may be pretty new as I thought they only made the storm, shadow and stealth. From reviews ive read of the stealth they vary greatly from gun to gun. some peoples are fover back and forth to the shop and need to be modded, others say theirs shoot perfect from the box.
That is what ive read about the stealth , hopefully they will have addressed it for the SSS.
