The little green laser that couldn't - Sun Optics Tactical Fore End Grip w/ 250 Lumen Light

The Light component is fine on this unit , but its my fault for not thinking hey the laser is on the Right. Not above or below the the rifle Barrel. So imagine you have 2 lines, one is the barrel the other the laser.If you want the green and or red laser to be perfectly zero you have to adjust the laser line to the left. Now the two lines aren't parallel so to put it short you can only match the zero of the laser to your sights at one specific distance, you go past whatever zero distance and the laser is off zero to the left. I use a trs-25 with this unit I zero the red dot to 100 yards and the laser to 25 ft. for CQB, I can say this unit saved my friends sons life when he broke in my house drunk at 1 am. without the flashlight on gun, I would have shot him. But it turned out ok he was just super drunk and cold, I let him sleep on the couch instead of shooting him. what a mess. But my advice is buy 2 separate units a light integrated Vertical fore grip and a separate laser that you can mount above or below the laser.
