246 Heavy Inserts by Altra
The 246 Heavy Inserts by Altra are engineered to enhance arrow performance by adding front-end weight and improving overall balance and penetration. Precision-machined from durable brass, these inserts are designed as a heavier upgrade for standard 246 diameter Altra arrow shafts. Their added mass increases front-of-center (FOC), helping stabilize arrow flight and deliver more consistent downrange accuracy. Built for a secure, concentric fit, these inserts ensure reliable alignment with field points and broadheads, making them an ideal choice for archers looking to fine-tune performance for hunting or target applications.
