It's a Picatinny laser sight. Believe it or not, it clamps on really securely with no special adapter. I love it. $24 on thinkgeek. Actually, there's a whole bunch online as cheap as $4

It's totally for intimidation purposes, but the EXDAT does shoot within a foot of the laser at a range of 27 feet. So yeah, it works !
