These moon clips are definitely better than the OEM moon clips; the slot between each round definitely seems to hold the rounds more securely, and allows a wider variety of ammunition brands/types to fit; for that I would give them 5 stars, but $40 for 5 moon clips seems like an excessive price for a simple stamped piece of stainless steel. I guess when you own the market, you can charge whatever you want; for value I give them 3 stars. So average is 4 stars.
