Magpul's infamous Flip-Up BUIS. Now even smaller and cooler.
Maybe "cool" wouldn't be the word you use to describe your AR's bolt-ons, but Magpul's reinvented MBUS Gen 2's are certainly slick. They're made from that same magically indestructible polymer that's practically claymore-proof. They're only 1.3 ounces installed, and now they're even smaller: Measuring just 0.5" tall stowed, 1.5" long when deployed, and 2.6" long when stowed, the BUIS Gen2 Magpul irons are about as compact as it'll get.
Spring-loaded auto deploy with easy-click adjustments.
The MBUS gen2 sports a spring-loaded button push that allows the sight to lock upward instantly. Dual apertures provide near and far sight pictures, and a detent knob provides simple windage adjustments, no tools needed.
