4mm Stainless Steel Half-Out Insert (Break-Off 100–80 gr) –  6 Pack
Heavy-duty 4mm stainless steel half-out inserts engineered for high-FOC hunting setups where strength, durability, and front-end stability matter most.
Each insert features a break-off design, allowing shooters to run either 100 grains for maximum penetration or 80 grains for balanced tuning, providing flexibility across a wide range of draw weights and arrow builds.
Designed specifically for micro-diameter hunting shafts, these inserts deliver improved impact resistance and reliable alignment when shooting fixed-blade broadheads and heavy hunting points.
