Still looking for input of anyone ' s got any . <| sep |> It takes years to learn all the skills required to play certain strategy games at even a high level . <| sep |> I kinda agree with the first point , like , we get it , lgbt people suffered hard , we know , stop telling the same story , make new happy ones , please . <| sep |> A lightning link works differently than an auto sear , but that ' s completely believable . With an auto sear , the auto sear itself catches the hammer in position 3 and the disconnector in position 2 . A lightning link requires no change in the trigger group and can be dropped into any nonblocked AR 15 off the shelf . The link pulls back the disconnector , dropping the hammer . An M 16 A 2 trigger group modified for use with a lightning link will have one disconnector that cannot be pulled back by the link , giving it safesemiauto . An unmodified M 16 A 2 trigger group with an auto sear works just like a normal FA assembly , but the second disconnector engages after the hammer drops three times . Thus , it has three instead of the two timing devices two disconnectors and an auto sear . Technically you could get FA in any AR 15 just by removing the disconnector or even adding weight to the firing pin , but you run the risk of an out of battery detonation maiming you . If you ' d like I ' ll send some pictures to explain .
