From Holosun, the LE420 Green & IR Laser is a class IIIa visible green laser aiming device with a coaxial mounted class 2 IR laser and IR illuminator for use with night vision devices. It features a 600-lumen white light. The LS420G has a titanium housing with a quick release Picatinny rail mount. Another feature is a mode/intensity selector switch.
I chose this for my T7 specifically because I wanted an all-in-one unit to go on my Hydra mount. It fits perfectly. So far the lasers are holding zero and everything works as designed. Only 2 complaints. I wihs is was a little smaller and the location for the remote SF switch is very tight so I had to trim my the plug a bit to fit. Oh, and the included pressure switch is too bulky which is why I replaced it.
