The high performance laser built into a rear sight specifically designed for all GLOCK pistols features a simple, ambidextrous "press and go" activation. The laser is easily programmable to either constant on or pulse mode. Another great feature is the "auto-off" feature that displays a unique flash after 5-minutes of operation and automatically turns the unit off after 6-minutes.
Made from heavy-duty, high carbon steel for added durability, the LaserLyte® RTB-GL rear sight laser has a black chrome finish for corrosion prevention. A great benefit of the LaserLyte® RTB-GL rear sight laser, besides the single-laser-fits-all-GLOCKS, is that the customer will not have to replace grips, internal stock parts or holsters. The LaserLyte RTB-GL rear sight laser is compatible with all Level 1 and Level 2 holsters including the BLACKHAWK! SERPA holster system. MSRP on the LaserLyte RTB-GL rear sight laser for all GLOCK firearms is only $139.95
