Daniel Defense A1.5 Rear Sight

Tuesday, April 28th, 2009

Daniel Defense set out to design a simple and reliable Back Up Iron Sight and they have more than succeeded with the A1.5 BUIS. The BUIS integrates the M16A1-style windage and elevation adjustments with a same plane small and ghost ring aperture. Once you adjust them, they are staying put.

The BUIS is manufactured from 6061 aircraft-grade aluminum and mounts to a 1913 standard rail. It slides on and locks in place via a slotted fastener which is threaded into a self-locking steel thread insert. Once it’s on, it isn’t going anywhere. The BUIS is fixed so no need to worry about it popping up at the wrong time or thin parts breaking off. Additionally, the BUIS was designed to not interfere with the charging handle.

Larry Vickers summed it all up when he said this about the BUIS, “Finally a rear sight that has everything you need and nothing you don’t”.
