i was looking around for a bipod to put onto my r700 today. decided to check ebay. the harris bipods are quite nice but pricey. and then i found some harris knock offs for a third the price. some even made by ncstar. so my question is this. is a by pod a bi pod? essentially its just a place to rest the front of the gun, like a portable sand bag of sorts. so will i notice a difference if i use a harris bi pod compared to a cheap knock off like this one?
