Easton 4mm FMJ Match Grade Features The Easton 4mm FMJ Match Grade shaft combines a 4mm ultra micro diameter carbon core with a 7075 alloy metal jacket a construction aimed at maximizing penetration while maintaining structural strength. This full metal jacket design is built in the USA to a tight straightness tolerance of plus or minus .001 inches giving competitive archers the shaft-to-shaft consistency needed for tight groups. The aluminum jacket also adds a degree of durability against impact damage compared to bare carbon shafts. Each arrow arrives with 8-32 point half-outs weighing 55 grains pre-installed simplifying point setup for the shooter. Pre-installed 4mm Microlite nocks reduce assembly time and help maintain consistent nock fit from arrow to arrow. The shafts in this 6-pack arrive fletched with 3 inch AAE Hybrid vanes already applied so archers can shoot straight out of the package without additional fletching work. This ready-to-shoot configuration also makes target pulling easier thanks to the shaft s slim 4mm profile. The Easton 4mm FMJ Match Grade is built for archers who want match-ready consistency without extra setup time.
