BB gun belongs to "Rifles" category and it two-handed weapon so it got 5AP.And, if i remember right i done topic about making pipe rifle craftable.http://fodev.net/forum/index.php?topic=7784
Also I think it was LagMaster who suggested that pipe rifle should be able to use any kind of ammo. Anyway bb gun does not have any kind of use beside cripple trolling and still any pistol is still better because of lower ap usage.
Why should it have lowered AP? It's damn rifle.Action points are translated to time needed to aim weapon and fire it, not the time needed to pull trigger. Otherwise every weapon would take 1ap to shoot.Just like in hunting rifle, you need to look down the ironsight of bbgun. This is shitty weapon to hunt with, and every newbie knows that. Also almost every other weapon for begginers is easier to get, so it is not an issue.I bet you just want to be able to disable whole enemy team with crippler character in first turn. Cunning plan I must admit. Black Adder would be proud.
i enjoyed using the bb to slowly attack a thief in NCR, chased them around the bazaar doing 6-8 dmg at a time
