INTEgRATED SAFETY WINgS & FORE-gRIP
DANGER
on your fore-grip hand below the string and
arrow flight deck when you fire your crossbow.
Otherwise, the bow string will severely injure or
amputate them when you pull the trigger.
The Storm RDX comes standard with rubber
safety wings which are designed to help keep
the shooter’s fore-grip fingers and thumb safely
below the flight deck while shooting. The wings
are bedded between the fore-grip and barrel.
If for any reason they are lost or damaged,
contact Horton for replacement immediately at
www.hortoncrossbows.com or 330-628-9245.
Keep your fingers and thumb
Safety wings are bedded between the
stock and barrel. They help prevent
thumb and finger injury and they
dampen noise.
