I disagree. Much faster to grab a leg and pull rather than finding a button (especially when cold and gloves or low light).
Accu-Tac is not a best all-around bipod, They're made for shooting .22s or free (modified free) recoil where you do not load the bipod. The guy who owns Accu-Tac comes from air guns, which is why they're so tight with no play. For heavy recoiling rifles I prefer Atlas or EI though.
Unless I'm shooting up and need elevation (or transitioning up and down), I almost never shoot prone with the legs straight out. I almost always put it on the spigot mount (as far forward as possible), put the legs forward at a 45 to get the rifle as close to the ground as possible, and use a small squeeze bag as rear support rather than a game changer or other big bag. I see lots of guys extending legs and getting the rifle high with a big bag, but I wasn't taught that way, and it seems less stable to me. If I need the gun high (like to see over grass coyote hunting) I go to a tripod rather than a long leg bipod,
Accu-Tac kind of sucks on a heavy recoil gun, because they're hard to load, don't stay put, and will jump on a hard surface even if you are perfectly positioned and do everything right. On low/no recoil rifles though they're damn near perfect IMO.
