Lightweight & strong, but flawed - GG&G Extreme Heavy Duty Swivel Bipod

Quality built, and will withstand typical abuse during the course of use. Legs extend utilizing gravity as they're not spring loaded, and do not allow for partial forward positions as they lock either raised up or turned down. The mounting base is quite strong, and occupies about two inches of rail but stays in place with a single recoil lug. The thumb knob used for adjusting cant and legs is rather small. On my unit the cant could not be locked, or tightened enough to prevent accidental rifle cant. Overall I rate the quality very high, but the features and functionality are a bit lacking.
