The Primary Adaptive Solution Systems Leg Extenders, in conjunction with the PASS adapters, allow you to turn your standard 6"-9" Harris Bipod into a 24"-27+" Bipod. These leg extensions can also be used on an Atlas bipod and utilize any of the available Atlas style feet or accessories. The carbon fiber construction is not only rock solid steady, but its guaranteed to withstand almost anything you'll encounter in the field.
Where the Gen II differ from the Gen I is that they do not require the spring loaded detent on the feet/legs to be manually depressed for removal from the adapter. The Gen II adapters feature a keyed slot that allows the bipod feet/legs to be removed simply by twisting and pulling away from the bipod.
