5mm Component System – Strength Meets Versatility

The K2 Arrow Co. 5mm component system is designed to give hunters the perfect balance of strength, precision, and adjustability. Using a two-part construction—a precision-machined post paired with a durable sleeve—this system provides dependable alignment, maximum durability, and consistent broadhead flight.

Choose from four weight options to customize your arrow build:

• Titanium Post / Titanium Sleeve (Ti/Ti): 65 grains – Maximum toughness with full titanium construction

• Titanium Post / Aluminum Sleeve (Ti/Al): 55 grains – Strong titanium post with a lighter aluminum sleeve for balance

• Aluminum Post / Titanium Sleeve (Al/Ti): 45 grains – Lightweight design reinforced with a titanium sleeve for added durability

• Aluminum Post / Aluminum Sleeve (Al/Al): 35 grains – Lightweight, cost-effective option without sacrificing consistency

Each component is built from Grade 5 Titanium and 7075 Aluminum, machined to exact tolerances, and requires adhesive installation to ensure long-term performance. Whether you’re building for speed, penetration, or balance, this system delivers the consistency and reliability K2 Arrow Co. is known for.
