I ordered the HARRIS BIPOD HBRMS 6″-9″ on Sunday and it arrived on Wednesday. You cant beat that for service. I also ordered the #6 sling stud adapter at the the same time I placed the bipod order. This adapter allows you to install the sling stud in the Bell&Carlson stock T-Slot channel.
I has one reservation going in and that was whether or not the 6″-9″ was the correct working range for the bipod. I can now say it was in fact the correct choice. Ill get some pictures this weekend of the 10 22 with the bipod in place.
