One of the main issues with the SCAR series of rifles, is setting them up with lasers. The folding front sight always seems to get in the way. This particular setup works very well however. A Kinetic Development or Midwest Industries extended rail allows the laser unit to be mounted out near the muzzle and lower in relation to the optic.
The problem with running a shorter extended rail is that you can’t have the front sight stowed AND the laser mounted. So the front sight has to be in the upright position, or… simply folded onto the PEQ. I shot this configuration for a few hours and the front sight never popped up. It’s a pretty slick setup. Although it triggers a lot of people’s OCD. haha
