Similar in design to Harris bipods, these are good quality folding/extending bipods suitable for deacts, airsoft, replicas and airguns. We have also used one on a live .22 rimfire rifle without issue. All metal construction with rubber feet and extendable legs giving height adjustment from 6" to 9". Requires a QD stud on your rifle to allow attachment - can then be attached or detached in seconds. Sorry - no international sales.
