The Magpul MBUS Pro Offset Rear is an all-steel 45° offset backup iron sight, clamping to any 1913 Picatinny rail alongside a primary optic.
The rear half of the fastest optic-to-irons transition in shooting — 45° offset, all steel, always ready.
The Magpul MBUS Pro Offset Rear Sight (MAG526) completes the offset sighting system: mounted at 45° beside your magnified optic, it pairs with the offset front to give a full iron-sight picture the instant you roll the rifle. Close targets, failed optics or fogged glass stop being problems — the irons are simply there, zeroed and waiting, without a single control to operate.
Like every MBUS Pro, it is machined from steel with a corrosion-resistant finish, folds to a tiny snag-free profile, and locks up with no discernible play. Windage adjustment is tool-less with positive clicks, making zeroing at the range quick work.
Why shooters choose the MBUS Pro Offset Rear
-
45° offset geometry — instant transitions from magnified glass
-
All-steel construction — survives what breaks polymer offsets
-
Tool-less windage adjustment — crisp, positive clicks
-
Tiny folded footprint — clear of the optic, clear of your hands
-
Play-free lockup — dependable return to zero
What the MBUS Pro Offset Rear fits
Fits 1913 Picatinny rails and sits at 45° so it runs alongside a primary optic rather than under it. You need rail space clear of your scope mount and rings, which usually means the front half of a continuous top rail. Zero it as a pair with the MBUS Pro Offset Front (MAG525) at your preferred close-quarters distance — an offset rear only works with an offset front set at the same angle on the same rail plane.
