The Magpul MBUS Pro Offset Sight – Rear mounts to an M1913 Picatinny rail and deploys at 45 degrees to the right-hand side, giving a back-up iron sight that stays out of the line of sight of a magnified optic and is ready for close-range work. Built from case-hardened steel with a QPQ salt-bath nitride finish, it stows at about 0.18 in above the rail and 2.0 in long and weighs 2.0 oz with hardware. The flip-over aperture offers 0.07 in and 0.19 in openings, and windage adjusts without tools at about 0.5 MOA per click on a 14.5 in sight radius (0.4 MOA at 20 in). It pairs only with the MBUS Pro Offset Front (MAG525). Made in the USA.
Can the MBUS Pro Offset rear be used with a standard front sight?
No — Magpul states it pairs only with the MBUS Pro Offset Front (MAG525).
Which side does it deploy to?
45 degrees to the right-hand side, for a right-handed shooter canting the rifle.
How high is it when folded?
About 0.18 in above the rail.
