Now till October 15, 2023, Easton Archery is offering a $30 rebate on select dozens of Full Metal Jacket Arrows ($10 on 6-packs). These are for fletched arrows only. Arrow shafts must be purchased with a standard fletch service to be eligible. See Easton Archery's web site for details.

Easton loves a challenge. And there's no bigger challenge 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.

Services Available Any service requested may delay shipment. Items with services applied are non-refundable.

Cut Shafts to Length:  Have your carbon arrows cut to length. The length is measured from the valley of the nock to the end of the shaft. Minimum length is 27".

Install Point Inserts:  Choose this option to have our experts install your Point Inserts in your shafts. We use epoxy style adhesives on all inserts and most points. Once they are installed, they are permanent. If you want us to use different inserts or adapters (i.e. brass point inserts), please put a comment on your order during checkout referencing what item numbers to use together.

Standard Fletch:  Our experienced fletchers will 3-fletch your arrow shafting with 5" shield left wing turkey feathers. The cock feather will be traditional barred and the two 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.

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