Easton loves a challenge. And there's no bigger challange than improving on their hugely popular Full Metal Jacket arrow shaft. But they've done it by packing all the power of the original into a new 4MM micro diameter (.166" inside diameter) shaft. The FMJ 4MM will give you unmatched knockdown power!

The Precision 7075 alloy jacket is bonded to a carbon core to provide minimal friction and extraordinary strength. Pair that with the included outserts for increased FOC. You'll get deeper penetration and increased likelihood of pass-throughs on even the toughest of big game.

  • Straightness: ±0.002"
  • Weight: ±2 grains
  • 4MM micro diameter carbon-fiber core with 7075 aluminum metal jacket
  • Increased kinetic energy
  • Better penetration
  • Lower friction
  • 4MM MicroLite™ nocks are installed
  • 4MM 8-32 aluminum half-out inserts (50 grains each) are included
  • Sold by the 12-pack

Services Available
Standard Fletch:  Our experienced fletchers will 3-fletch your carbon shafts with 5" shield left wing TrueFlight feathers. The cock feather will be traditional barred and the 2 hen feathers will be your choice of white, yellow, red, or fluorescent lime (same color for all arrows). Hen feather color can be requested and will be fletched on a CLEAR cap wrap. No substitutions. Allow 4-7 additional business days for your order to be processed.

Cut Shafts to Length:  Have your carbon arrows cut to length. The length is measured from the throat of the nock to the back of the point. Minimum length is 27½".

Install Inserts:  Choose this option to have our experts install your Point Inserts in your shafts. Please Note: If you select this service without selecting the "Cut to Length" service, your shafts will be cut to the stock length (as specified in the chart above). Please Note: We use epoxy style adhesives on all inserts and most points. Once they are installed, they are permanent.

If you prefer to customize your shaft with additional options, please use our Arrow Builder
