Best bipod adapter i have found - Versa-Pod HD Picatinny Rail Bipod Adapter

I have mounted one of these adapters to the bottom of each of my rifles varying from fiberglass bolt action hunting rifles to all ar platform rifles. The only requirement is at least 3" of pic rail on the underside of the forearm. This allows me to only have to buy one versa-pod bipod which can be carried separately and attached when or even if necessary making for much easier shoulder carrying while hiking and balance and swing while shooting off hand. As i hunt prairies for deer and mountains for elk this modular design gives me the best of all worlds. I highly recommend.
