If you are buying fiber optic inserts for your sights by the inch, you are getting screwed.
If you are anything like me, you prefer a fiber optic front sight on your competition pistols. Being that the fiber optic insert is just a small piece of plastic, they tend to break fairly often. I recently noticed some cracks in the fiber optic insert on the front sight on my S&W M&P Pro, and decided to order a new insert. What I found was shooting related retailers were selling 3-4″ of the stuff for $5-$10 a piece!
What a ripoff! I started looking a little deeper and found a retailer that sells fiber optic rod by the meter, for less than the unnamed shooting related retailers were selling a measly couple inches.
After a couple google searches, I found that my M&P Pro uses a 0.06″ (1.5mm) insert, and my Glock 17 with Sevigny sights takes a 0.040″ (1mm) fiber optic inserts.
Anyways, I came across a website called www.fiberopticproducts.com that sells fiber optic “fluorescent fiber” in 3′ sections for about the same price the other guys are selling a couple inches for. I ordered late last week, 3′ of red fiber showed up today. Awesome!
