AR-15/M-16 Flip Up Front Sight

Looking for an affordable backup Iron Sight for your AR15 rifles? This AR-15/M-16 Flip Up Front Sight allows you to flip the iron sight up and down depending on your needs. The quick-detachable BUIS (Back Up Iron Sight) fits on Picatinny and Weavery Style AR15 Rails and it locks in place with retention thumb nut. MARFLF AR15 Flip Up Front Sights are designed to only fit the gas block rails. They are designed to fit weaver or Picatinny railed AR15 gas blocks.

There are basically two different heights of back-up flip up sights. They are designed to fit gas blocks or on quad rails. Since most gas blocks sit below the optics rail on an AR15 receiver, they are taller to compensate for the lower mounted rail on the gas block. Front sights are designed to fit on a handguard quad rail. The quad rails are usually at the same height as the receiver optics rail. The flip-up front sights are shorter in height vs the ones designed to fit on gas blocks. There are not designed to be mount on quad rails, as the front sight post will be too tall. If you need a tool to sight your AR-15 Rifles, we have AR15 Front Sight Adjustment Tool for sale.
