Easton 4MM AXIS Long Range carbon arrow shafts provide a precise foundation for building hunting arrows intended for extended-distance shooting. This package contains 12 bare shafts in the 250 spine configuration, giving archers the flexibility to select and install their preferred vanes and points. Each uncut shaft has a 33-inch stock length, a listed weight of 9.8 grains per inch and a measured spine deflection of 0.250 inch. The all-carbon construction and ultra-micro 4mm profile are engineered to keep shaft weight manageable while reducing friction during flight and penetration. A 0.244-inch outside diameter gives this configuration its narrow profile, while the black micro-smooth finish provides the familiar appearance of the AXIS Long Range series. Easton rates the standard-grade shafts for straightness within plus or minus 0.003 inch. Each shaft is supplied with a pre-installed 4MM Microlite nock weighing 6 grains, and the package includes spine-specific number 4 aluminum half-outs weighing 50 grains each. These half-outs use standard 8-32 threading, allowing the completed arrows to accept commonly available 8-32 broadheads and field points; Easton specifies a 5/16-inch field-point diameter for the 250 spine shaft. Because these are bare shafts rather than finished arrows, cutting, squaring, component installation and fletching can be tailored to the archer's bow setup and preferred finished-arrow configuration. Correct shaft length and spine selection should be confirmed for the bow's draw length, draw weight and point weight before assembly. Manufactured in Easton's Utah facility, this dozen-shaft package is suited to bowhunters and archery builders seeking a stiff, small-diameter carbon platform with included nocks and front components.Specifications and Features: 250 spine; 0.250-inch deflection 33-inch stock length; 9.8 GPI 0.244-inch outside diameter Ultra-micro-diameter all-carbon construction Black micro-smooth finish Straightness tolerance: 0.003 inch Count: 12 bare shafts Includes 50-grain 4MM 8-32 aluminum half-outs Pre-installed 6-grain 4MM Microlite nocks Compatible with standard 8-32 broadheads and field points Made in the USA Brand/Series: Easton 4MM AXIS Long Range Product Type: Carbon Arrow Shafts Manufacturer Part Number: 130110 UPC: 723560301102
