This scope adapter allows you to mount a micro sight (T-2, T-1, H-2, or H-1) to the tube of a magnified optic. It's available in two sizes: 30mm and 34mm (should match up with scope diameter).
We had the opportunity to provide a training video and a 'train-the-trainer' course to US Special Operations Command (SOCOM) on behalf of Aimpoint for the 'Enhanced Combat Optic Sight- Optimized' or 'ECOS-O' program. That program provided special operations soldiers with an Aimpoint Micro T-1 piggybacked onto the tube of a Leupold scope. The T-1 serves two purposes in this system. first, it allows the shooter to use the rifle in close quarters. Second, it makes acquiring distant targets MUCH faster. This mount, coupled with an Aimpoint Micro sight, is an excellent way to dramatically increase the capabilities of your sniper rifle, particularly in urban environments.
