Most people prefer the twist guns.  O-Ring guns are what people might call “old style”, they were the first ones.

The insert, plug, or adapter (whatever you want to call it, everyone calls it something different) is there so you can place the cut semen straw directly into the sheath and then into the gun. There is less waste with a “insert”.

You don’t have to use the insert unless you are using 1/4cc straws and then you have to use them

Twist sheaths only come with the insert.
