Holy crap. I just looked on Spike Tactical's website and 5.56 uppers are 6-8 months back ordered and the 300 BLK Out uppers are 12 months out! Crazy. I think I'll go hug my rifles now
You might be better off buying a whole rifle if you must have one in firing order in the next 6 months. I saw some on AR15.com classifieds for a little over $1000. That's about what they were going for 4 yrs ago. About a 200-300 premium in most cases. So you have to decide what it's worth to ya. Good luck.
