Great Bipod! It works a little different than what I was expecting, ut this thing outperforms a lot of other bipods I've seen or used before. When you pull down on the legs they lock position automatically when they reach their full extension, and by hitting the little metal buttons (?) they retract back to their normal position. The legs are spring loaded, so they stay in place and require no additional buttons/ slides to lock the bipod in the up or down position. This thing looks completely bad$ss on any M4/16, but I would recommend to it to any/ all airsofters/ LE/ military personnel. For airsofters though, it gives your AEG that nice operator look and gives you a sturdy platform to rest the weapon on.
Well built, high quality metals
spring loaded (though sometimes a bit scary and noisy)
quick extend/ retract legs
i personally like the rubber ends at the bottom cause you can use it on any surface
comes with a swivel stud mount in case you don't have RIS/RAS for that sniper of yours.
Bolts on via thumbscrew, not Allen key... a lot easier to change loadouts in between matches.
none really, unless you want to say it makes too loud of a noise when putting the bipod up or down.
