Will this fit the magpul front site? — 4 Answers

These fit the Magpul MBUS Gen 2 polymer sights, but for the MBUS PRO steel sights you need to get the MBUS PRO models of Blitzkrieg Sights. The new polymer MBUS Gen 3 sights are different than both of their previous models and require a new type of post specific to the Gen 3.

False. I have them on three of my mbus front sights. I have the tritium dot and painted chevron models (same as this).

The chevrons ARE in fact compatible with Magpul BUIS. They AREN'T compatible with Magpul BUIS Pro models though. You'd need the Blitzkrieg Components spike or post.
