i got this laser for my TM 5-7 to make it look *almost* exactly like the 5-7 from the Splinter Cell series. This is a fantastic little piece of kit!! its pretty bright, bright enough for me to see it in daylight. the on/off lever is pretty nice, and is ambidextrous. if you have a small SMG that has a rail, such as an mp7, this thing look very good those as well. for 20 dollars, you really can't beat this little guy.
P.S. this is a RED laser, not a green laser.
-cheap price, yet very high quality
-easy to mount
-looks great on any pistol
-easy to adjust for windage and elevation
-look good on small smgs, such as an mp7, mp5, or maybe even an AR.
i cannot think of a single con!!!
i Highly suggest you buy one of these!
