A fiber optic (FO) insert in the front sight blade is one of, if not the, most popular sight options for action pistol competitors. Our Fiber is made with Polystyrene Plastic. They’re bright, fast to acquire, and now they are a common feature on many factory guns.We provide the Fiber Optic Refill Pack. It’s a convenient six-inch tube with multiple rods in red, green, or amber.


A set of fiber optic replacement rods is handy to have as replacement parts, too. With basic tools and replacement rods either is a two minute job, whether at home or on the range. These feature tough fibers that are both chemical-resistant and heat-resistant. They amplify light to ensure visibility at low-light conditions or even complete darkness. For an everyday-carry or home defense gun, this fiber replacement pack will take it to the next level.


All of our Fluorescent Fiber is made by PMMA. The standard diameter of the fiber is 0.5mm,  0.75mm, 1.0mm, 1.5mm, 2.0mm, 3.0mm.The sizes we carry will fit most Gun and Archery sights. Most manufacturers have their fiber made when the sight is designed so purchasing an aftermarket fiber may not fit exactly into your sight pins. You may need to heat or drill your sight to fit, but 80% of the time our fibers fit!  ALL FIBER IS SOLD PER METER. Discounts will apply based on volume.

All fiber will have a ± 5% and will not always fit your exact sights due to different manufacturing.
