BlackHeart Crossbow Rail Lube

Every crossbow shot drags the string across the rail. Ignore that friction and it takes speed, accuracy, and string life from you.

A dry rail wears on your serving with every shot, and most shooters do not notice until the damage shows.

Same Shot, Every Time: The lube creates a slippery surface for the string to glide across. Shot consistency improves because the string meets the same rail every time.

Serving That Lasts: Less friction means less wear on the center serving. The part of the string that takes the most abuse gets protection.

Speed You Keep: A slick rail means increased velocity. The energy goes into the bolt, not into drag.

In the Blind: You put a thin line down the rail before you cock the bow. The scent-free formula gives a deer downwind nothing new to smell.

Goes On Right: The viscosity is tuned for application, so a small amount spreads along the rail. Made in the United States.

A hunter who cares about the shot cares about the rail it rides on.
