Helo, Fergus, welcome to WareWolf world!
I was introduced to Harris bipods in July,1976, not only our Nations 200th birthday, but also the year Donna and I packed up the kids and moved to Deer Lodge, MT!
My intorduction to the Harris product was rather rude - on a rockshuck shoot, in the scab-rock country of eastern Washington state, that summer, my old pal Joe had all of his rifles equipped with HARRIS bipods . . and though he cannot [to this day] "hold a candle to light my sights", on THAT trip, he shot rings around me at three hundred yards and beyond . . . I've never gone huntin' without a HARRIS bipod since that rockchuck shoot.
There are a variety of options/models to choose from; you may need more than one! ;) They are light weight, durable, quiet, deliver unexcelled field accuracy potential and are worth every penny! Good shootin'! R.G.
