It is a red dot sight, just like a "No Peep" only using a digital readout. Seems pretty cool, and I might be in the market for a different sight already. With the quality issues Apex Gear has, it might be better to just avoid them, return it while I still can and get into a new sight. This is a no peep sight, so that brings that variable into play also, but would you ever try it? $150 for the whole set-up...just get the fixed position sight and have it at 20 yards. Anyone?
