Magpul MBUS Pro Flip-Up Front and Rear Sight Set
The MBUS Pro (Magpul® Back-Up Sight) is a corrosion resistant 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.

My only choice on backup sights now, hands down.
Had the MBUS polymer setup and liked the quick flip up feature but hardly ever used them due my EOTech taking the bulk of the job of aiming on rail. Upgraded to PRO for the flush low profile and black semi-gloss look compared to the polymer's general look. Though, some may ask "Why pay more if they're just gonna sit and only be used as a backup?" and I'd reply "Because I got a sick price on them from GunMagWarehouse!" Hahahaa!
The finish is a little delicate (scrapes right off), the electro-welds seem too small but product works well - the comparison being made to last century's Chinese and Russian products, only time will tell if premature breakage is a design feature. The mag even worked for about 60% of capacity when I forgot to wind it - using only the residual spring winding pressure to set the follower for loading. This just may be the ticket if the Z virus kicks in.
