The MBUS Pro. The all-steel back up sighting solution that delivers maximum functionality and strength with minimum bulk at a price that’s even smaller than its size. The dual aperture, windage adjustable rear and no-tool, elevation adjustable front excel in all 1913 Picatinny rail mounting applications, including rail-height gas blocks. Positive detents keep the MBUS PRO front and rear at standard AR sight height when deployed, and so low when they are stowed that you’ll never notice them until they’re needed. Narrow width front is compatible with most IR aiming laser and light installations for the professional user.

SPECS:

All steel construction
Selectable large and small same-plane apertures
Positive detents in both the up and down positions
.375” height above rail at mid-point when stowed
Standard AR sight height when deployed
Windage adjustable with low-profile knob

Perfect for my needs (16/09/2013)

Small and solid. Locks well in the up and down position. Great BUIS.

recoil sensitive? (31/10/2013)

my S&W M&P10 application suffered from inadequate detent s with (so-far) commercial ammo shake-down.
I have as-yet to test after (VERY carefully) dismantled & stretched the main folder detent spring.
I'm afraid to take apart the aperture pivot to try the same on that aspect of the rear sight.
Otherwise, I am ecstatic with the fit & finish!

Solid rear sight. (14/06/2015)

Sold sight. Lays super flat! Build is very solid. No jiggling. Adjustable window for near and far shots.
