My spring tensioned 6-9" Shooters Ridge 'rock mount' bipod spring snapped. Called Russels where I bought it, and they gave me the 1-800 number for Shooters Ridge. The girl was really nice and helpful. Says they are all out of springs, so she is just going to send me out a new bipod, even though its 4 years old, on their dime. Just thought I'd let you all know, just in case you all have broken bipods all of a sudden.
