Here's your chance to build your on own Sonic KE to SLICE THE WIND & HIT HARD for an awesome price! The Nock On Sonic KE is a 6mm super straight, extremely consistent high-performance arrow that comes standard with 75/50 grain break off brass inserts for the front. The Sonic KE is a custom engineered arrow that’s perfect for both Hunting and Target archery speeds while boosting FOC up to 25% when using the provided custom brass inserts. The Sonic KE is built in the USA using Easton’s seamless ACU-Carbon process for 100% weight and spine consistency from shaft to shaft and from dozen to dozen. Lighter overall mass weight provides for a wider-range of arrow build options using the provided 75/50 break off inserts. This shaft is perfect for anything ranging from the Total Archery Challenges to Bowhunting large game animals.
The Nock On Sonic KE is a SELECT GRADE shaft (+-.0015) that is pre-sorted from the factory giving you the highest quality shafts for straightness and weight.
Save Big, Lose Nothing
The Sonic KE gives you all the accuracy at the best price. These arrows are priced right, with you getting big benefits without losing on straightness or weight tolerances.
Sonic KE Arrows Core Benefits
-
Enhanced Kinetic Energy: Standard 75/50-grain brass inserts boost FOC up to 25% for superior downrange ballistics and momentum through your target.
-
Premium-Grade Construction: SELECT GRADE shafts (+-.0015) presorted from the factory for exceptional straightness and weight consistency.
-
Versatile Performance: Perfect balance of speed and impact for everything from Total Archery Challenges to taking down large game animals.
Maximum Front-End Weight Options
The Sonic KE comes standard with custom 75/50 break-off inserts, giving you control over your setup based on your shooting needs. These inserts allow you to boost your FOC dramatically while maintaining optimal overall arrow weight. The shaft’s lighter mass weight compared to Axis or FMJ arrows means you can run the full 75 grains up front and still maintain the total arrow weight you’re used to.
When you choose the full 75 grains of brass, you’ll get 25% more FOC compared to standard arrows with 50 grains of brass. This means better wind-cutting ability and increased momentum that carries through your target — exactly what you need when it matters most.
Spine Selection Tip: For maximum performance with the 75-grain inserts, select one spine size stiffer than your normal arrows with aluminum inserts.
High-Performance American-Made Shafts
The Sonic KE arrows are built using Easton’s proven AccuCarbon process right here in the USA. This means guaranteed straightness and weight tolerances from shaft to shaft and dozen to dozen. These 6mm shafts provide the perfect balance — stiff enough for consistent accuracy but light enough to maintain speed with the heavier front end.
Each arrow is a SELECT GRADE shaft (+-.0015) that’s presorted at the factory, giving you only the highest quality shafts for straightness and weight consistency. This tight tolerance control eliminates variables from your shooting equation, allowing you to focus on your shot execution rather than worrying about arrow inconsistency.
Versatile Applications
Whether you’re heading to a Total Archery Challenge, shooting 3D, or hunting big game, these arrows deliver the performance you need.
The lighter shaft weight combined with the heavy front end gives you options that weren’t possible before, maintaining speed for longer distances while still getting the penetration and durability benefits of higher FOC.
For hunting setups, the increased FOC dramatically improves flight stability and penetration on game animals. For competition, you’ll get the accuracy benefits of premium-grade arrows at a price point that won’t break the bank.
