Rocky Mountain R38100 Hypodermic NC 100GR Broadhead Arrow Tips

The Rocky Mountain R38100 Hypodermic NC is a 100-grain broadhead designed for bowhunters who demand a compact ferrule profile without sacrificing cutting diameter or blade deployment reliability. The hybrid hypodermic tip combines a needle-like point with a streamlined body that improves in-flight accuracy compared to traditional broad-profile designs—useful whether you're hunting from a stand or practicing at distance before season.

What sets the Hypodermic NC apart is its collar-free blade lock system. Instead of relying on a shock collar, O-ring, or dental band, finger-like tabs on the Slip Cam pivot point anchor the blades securely in the closed position. This design eliminates one more potential failure point while keeping the broadhead compact and field-tip accurate. On impact, the two blades deploy instantly to a full 2-inch cutting diameter, creating the wide entry wounds that matter for blood trails and ethical, efficient kills.

Built with a machined stainless steel ferrule and .035-inch thick blades, the R38100 is engineered to handle the speeds and forces of modern compound bows. The package includes three broadheads, with replacement blades available separately (SKU R38105) so you can practice and hunt without constantly rebuilding the entire head.

Frequently Asked Questions

What arrow shaft weight and spine do I need for the 100-grain Hypodermic NC?

You'll need to match your arrow spine and total weight to your bow's draw weight and length. A 100-grain broadhead sits in the mid-range, so confirm your arrow manufacturer's recommendations for your specific bow setup. Do not guess—incorrect tuning affects accuracy and safety.

How is the blade lock different from other Rage broadheads?

The Hypodermic NC uses finger-like tabs on the Slip Cam pivot point to anchor the blades in the closed position, eliminating the need for a shock collar, O-ring, or dental band. This design simplifies assembly and removes a potential weak point while maintaining reliable blade retention until impact.

Can I buy replacement blades separately?

Yes. Replacement blades are available under SKU R38105, so you can keep the ferrule and resharpen or swap blades without replacing the entire broadhead.

What's the difference between the Hypodermic NC and other hypodermic tips?

The NC model features a narrower, more needle-like ferrule profile than standard hypodermic designs, which improves in-flight accuracy and field-tip performance. The 2-inch cutting diameter and 100-grain weight remain consistent with the broader hypodermic line.
