Knights Armament KAC "vintage" Taupe front sights

At Charlie's, we have collected, or curated some vintage anodized front sights over the years.  For Knights, the term "taupe" is and has been very subjective.  It runs from a light tan to an FDE, desert sand, medium brown to a dull green. And, trying to capture these nuanced shade differences in photos is very hard.

Most clone collectors are looking for the vintage browns and dull gray-greens for a perfect Mk18 clone, for instance, and KAC has not made that color in years.

The current new model 99051 front sights are more of a medium tan Cerakote, or that is how my eye sees it.  The older colors were anodized aluminum, and that gives you different hues in every batch.

Note on parts at Charlie's:  We stock these, purchased from KAC and collectors, and LE trade-ins, etc., for the purpose of using on our very specific custom and production builds.  When we have some extra parts, we make them available to you to purchase.  We spend a fair amount of effort in sourcing, tossing out the bad ones, and storing in inventory special parts like this.  Our pricing reflects that.  We are not trying to make a market in spare collectibles, but if that is what you want, you came to the right place.  Just, please, no complaints on the price.  This is mostly for our manufacturing inventory, and make it available when we can.

Pricing on these is much higher than a new front sight, as they are hard to find, and Charlies ends up paying much more for the sights.  We source these from individual collectors, and other KAC dealers who have very old inventory.  The price given below is for the best quality and best colors.  We will have a few different colors, quality (used and new) and price points.

Charlie's grades anything used that we sell.  These sights are Excellent to Very Good Quality, A+ (new), A / A- (Excellent Used) and B+ (Very Good Used).  The used sights show extremely little signs of use or wear, but might have a small pencil-mark sized scratch.  Considering that you will place these on real weapons, they are all perfect. Some sights have NSN and part numbers, some are older and do not have.  Let us know your preference.


The colors are:  Chocolate Brown, Dull Green-Gray, and Dark Taupe / FDE.  When you order, put your preference in the comments section, and we will fill your order.  If we don't have your request, we will contact you and tell you what is available.  If you are not happy, you can cancel your order without penalty.  If you order and you are not happy on delivery, you can return and pay only for shipping.  We think you will be happy.  We cannot take pics of the individual sights.  We have done our best to give you representative pics here.


Also, note that Charlies also has truly used sights with varying degrees of bumps and bruises, that we sell below the price of our new and excellent quality sights.  If interested, email us.  What is listed here we prefer to call "vintage"
