Precision Reflex Inc. co-witness mount. This mounts secures to the carry handle via a thumb screw. The mount then extends forward from the carry handle, drops down, then extends over the handguards, and provides a rail over the handguards for mounting optics so that they may co-witness with iron sights. I tried this with the Holosight and the A1 sights. The fatter base of the Holosight didn't allow it to quite co-witness with the A1 sights. I'm not sure how it would work with a different type of red dot sight or A2 sights. Very good condition Paid over $100 for it. Will sell it for $50.00 Shipped.
