Solid solution for rifle light - Streamlight ProTac Rail Mount HL-X Pro Long Range 1000 Lumens Gun Light w/Remote Switch

This is a good, complete package for a light for a carbine or rifle. It is BRIGHT and the light carries a long way out. The end cap has an on/off switch plus the input for the tape switch (because tape switches can fail). The light itself is a little bulky; however, the MLok mount will tuck it in pretty well on a normal handguard. The gizmos to attach the tape switch to a rail are not great - there is an aftermarket solution that I need to look into. That said, this is a helluva good light for the price.
