The lightweight, streamlined design of the Daniel Defense A1.5 Fixed Rear Sight makes it the optimum back up iron sight for shooters using today’s most popular reflex optics. Its well thought out design does not impede the use of the charging handle on AR-15 style rifles. The one-piece design makes it easy to install to any Military Specification flat-top upper receiver and the sight is secured to the upper using a slotted fastener which is threaded into a self-locking steel thread insert.
