Midwest Industries (MI) and US-PALM have expanded their line of optic mounting topcovers for the MI Universal AK Handguards. The newest topcover, the ML2 Topcover, will allows shooters to mount the 30mm Aimpoints like the M2, ML2, M3, ML3, and others.
The best thing about the ML2 Topcover is that it allows the Aimpoint to be co-witnessed with the iron sights. The cowitness height will vary based on the tolerances of the particular AK on which the topcover is mounted. It will vary from an absolute cowitness to a lower 1/3 cowitness.
You can read more about the ML2 Topcover on the MI website.
