Stream light pro tac tail mount 2 - Streamlight ProTac Rail Mount 2 Long Gun Light

The light is easy to mount if you use the 1913 rail or the enclosed m-loc mount. I used the m-loc mount and found that easy to mount and install the light. After putting in the batteries I found it’s bright enough for pretty much anyone’s needs for the cost. About the only downside is that the instructions are in such small type that those of us who need glasses might struggle to tell what to do.
