I recently bought a new Darton Maurader and with that got new sights the cobra sidewinder lx. I can not get this bow sighted in properly as my 20 yard pin is at the bottom of the sight and it is adjusted as far down as it will go and ihave no room for any other pins. The only thing i can think of is to raise my peep, but that will affect my achor point. Has anybody else had this problem? What can i do?
