Reffering to a picture of this installed to my G&P Aimpoint.

It does the magnifying trick just right, and it makes the common Aimpoint look like a half ACOG, half Scope. Adds to the overall appeal of the gun very much.
I omitted a star out of the final rating due to that it couldn't be twisted all the way into the threaded tube.
