Love profile sight set - NcSTAR Picatinny Low-Mounted Deployable Sight Set

These are just repackaged DLG Tactical Low Profile Sights and I'm totally cool with that since those were out of stock. I own several sets and they work just as good as any other absolute co-witness height back up sights. You have to manually flip them up but that's not a big deal to me. I own some high end BUIS that also need to be manually deployed. For the price you get a decent BUIDS set. I'll definitely be getting these again.
