Ncstar's gen2 ar15 riser raises your picatinny rail platform by.75" which aids in getting low profile optic mounts to a more comfortable cheekrest height and shooting position.It mounts onto the picatinny rail of your ar15/m4 receiver by a locking quick release, which allows you to quickly attach and remove your optics and maintain zero.The gen2 model has an updated shape, a locking quick release mount with shorter lever, and is lighter than the previous version.A see-through channel below the rail keeps the mount lighter, and allows you to use factory iron sights.
