Dinger's Review of Q Sugar Weasel, 5.56x45mm NATO, 16 inch, Upper Receiver

purchased the upper because I like to cry first and think later. upon wiping the tears and working the overtime to keep the billsharks off me for the 3rd time this month, Q makes a quality product, so naturally I mated it with a budget Resilient Arms Simple Man. After watching a video where the upper melted after the first 190 rounds of cyclic fire (i mean that’s bad bad) I cried on the inside some more. I watched a few more videos where the far less spongebrained of our kind took the upper out of the box and youtubed some instructions on adjusting the gas block. Watch the videos, adjust the gas block, lubricate liberally. The pros, its light, its sleek, it cycles well, the details The only downside I have is, Q and not per se OpticsPlanet does not give any kind of simple instruction manual on the adjustment, or maybe the allen keys neccessary to do so.
Pros:
  • Lightweight
  • sleek
  • Performs as advertised
  • sharp features
Cons:
  • No instruction
