The V-Tac Valken Mini Riser Mount 3/4 Inch High- 3 Slots allows you to mount scopes up high on the top rail of your gun. Slightly taller than other mounts.  Helps with using a face mask and lining up sights on the field. Mounts on all standard top rails for all AEGs.The 3-slot larger style is good for very small minimal scopes/reflex sights, etc. All metal construction.  Skeleton see-thru bottom for iron sights.

Very small footprint on your gun.  This is just a little bit taller than the 1/2 inch mount (pics are similar).
