Attention all crossbow hunters ? this broadhead is for you. This insanely sharp mechanical broadhead produces a large 1-3/4″ cutting diameter starting with the bone crushing stainless steel tip and ending with three razor-sharp 0.035? stainless steel blades. The internal blade locking mechanism provides reliable blade retention and prevents the blades from prematurely deploying. Expect field point accuracy and reliability with every shot from the Siphon XB broadhead.
