The Rocky Mountain R38400 Hypodermic NC crossbow broadheads deliver the wide-cutting performance serious crossbow hunters demand in a 125-grain design engineered for flat trajectories and hard-hitting impact. These mechanical broadheads feature the Hypodermic hybrid tip—a needle-like ferrule profile that cuts through the air cleanly for field-tip accuracy, then unfolds on impact to create a devastating 2-inch cutting diameter. Built around a no-collar blade-lock system, they anchor securely in flight without shock collars or O-rings, so you get one less thing to tune and more reliability in the field.
The two .035-inch thick blades deploy on contact and sweep back into their wide cutting angle, designed to produce the kind of blood trails that end tracking jobs fast. The machined stainless steel ferrule handles the extreme speeds and G-forces of crossbow bolts, while the Hypodermic design trades brute cutting width for penetration efficiency—you get the wound channel serious hunters rely on without sacrificing pass-through potential. Each pack includes three broadheads ready to hunt, and replacement blades are available separately so you can keep your heads in the field longer.
Whether you're hunting whitetail at 40 yards or setting up for a longer-range opportunity, these 125-grain heads will group like field points and deliver the terminal performance that justifies a mechanical broadhead over fixed-blade alternatives. The no-collar retention system means less fiddling before the season and more confidence in your setup once you're in the stand.
