Received the production-run of aluminum moons from Wyvern Creations. They are even better than the ones He sent for testing previously. Now have a threaded hole in the back for a arrow puller. They look great, are much stronger than plastic nocks and, judging from previous accuracy tests, perform well too.
I highly endorse them for anyone shooting a bow requiring moons, esp fast bows like the 175 Terminator, Cyclone and the like.
