The Nock On Full Metal Jacket Pro Series delivers heavy-hitting performance with match-grade precision. These 5mm Easton arrows feature a carbon core wrapped in an aluminum outer jacket, engineered for maximum penetration and less wind drift.
I’ve used FMJs for over a decade during countless hunts and target competitions because they deliver when it matters most. Each arrow has +/-.001 straightness tolerance with weight and spine consistency that eliminates the tedious process of arrow sorting. The pre-installed brass 50/75 grain break-off HIT inserts and Broadhead Adapter Rings (BAR) create a deadly accurate system right out of the box.
Available in 250, 300, 340, and 400 spine sizes, these arrows are built for hunters who demand field-proven reliability.
Core Benefits
- Superior Durability: Carbon core with aluminum jacket creates a robust shaft that withstands impact
- Match-Grade Precision: Guaranteed +/-.001 straightness with spine and weight consistency
- Deep Penetration: Heavier overall weight combined with brass inserts that deliver knockout power
- Wind-Defying Performance: Aluminum jacket minimizes crosswind drift for better long-range accuracy
Premium Construction and Performance
Carbon Core With Aluminum Jacket
The Full Metal Jacket Pro Series combines a carbon inner core with a precision aluminum outer jacket. This hybrid construction delivers the best of both worlds: carbon’s lightweight strength and aluminum’s consistency and durability.
The aluminum exterior provides unmatched straightness while minimizing wind drift during flight. When passing through targets or game, the smooth aluminum exterior reduces friction for superior penetration.
Match-Grade Selection Process
Every arrow in your dozen is guaranteed to be within +/-.001 straightness tolerance.
These match-grade arrows eliminate the frustrating process of sorting through shafts to find the most consistent performers. Each dozen is weight-matched and spine-consistent, giving you ballistic precision that produces tighter groups downrange.
These are literally twins cut from the same three-mile continuous arrow manufacturing process, ensuring identical performance from arrow to arrow.
Brass HIT Inserts
Standard with every FMJ Pro Series is a break-off brass insert system.
Each arrow comes with a 75-grain brass insert that can be easily broken down to 50 grains, giving you the flexibility to customize your front-of-center (FOC) weight distribution. This higher front weight percentage maintains momentum and minimizes wind drift to boost long-range accuracy and penetration.
The brass inserts are installed with a specialized hot melt that allows for broadhead indexing when needed.
Broadhead Adapter Rings (BAR)
The included Broadhead Adapter Rings provide three critical advantages: perfect broadhead alignment, increased durability, and shaft protection.
These precision-machined rings create a perfectly squared edge with a tapered bevel that aligns broadheads for true spin and flight. The BAR system dramatically increases shaft durability by protecting against linear tears and center plunges when hitting extremely hard bone or other dense materials.
Pre-Installed Green 5mm Nocks
Each FMJ Pro Series arrow comes with pre-installed green 5mm X nocks.
These tried-and-true nocks provide consistent string release and are compatible with most lighted nocks on the market. The 5mm diameter creates the perfect balance between durability and weight while maintaining excellent component compatibility.
Field Performance
The Full Metal Jacket Pro Series excels in hunting scenarios where penetration and durability are critical. At 570 grains (300 spine with 75-grain insert at 29.5″ length), these arrows provide knockout power for elk, moose, and other large game. The heavier overall weight quiets your bow and delivers more momentum downrange for pass-through shots on big game.
For whitetail hunters and mid-range shots, the FMJ provides match-grade accuracy with devastating terminal performance. The aluminum exterior makes these arrows easier to pull from targets than all-carbon shafts, perfect for winter practice sessions and 3D competitions when temperatures stiffen target foam.

The Right Arrow for the Hunt
The FMJ Pro Series is ideal for hunters seeking maximum penetration and durability. The heavier overall weight makes these perfect for elk, moose, and other large game hunts where knockdown power matters most. They’re also excellent for whitetail hunters who want quieter bow performance and easier arrow removal from targets during practice.
For those who want all the benefits of the FMJ system with maximum consistency, the Match-Grade Pro Series delivers premium performance that eliminates guesswork. Stop wasting time tuning and sorting arrows. Grab a dozen FMJs and experience the confidence that comes from shooting what I use in the field and on the podium.
