These aren't exactly new but I don't think they are that well known
GG&G makes a rail mounted bipod that competes with the BT Industries Atlas Bipod system.
It is a tough and rigid bipod that goes from 7"-9.5".
It folds up using the push levers on each side and locks in either the folded/closed and down/deployed position. However they have released a newer version that can fold to a 45 degree position and swivels as well as cants like the Atlas.
It is quite light at 11.5oz
MSRP is about 175$
For those that don't like the Atlas, which for me still stands as the best non-F Class bipod out there, it is a close second and provides an alternative for those looking for something different.
