This is a simple idea that makes a lot of sense. Knight’s Armament Company has a new rail mounted front site out called the Micro Flip Front Sight. It is becoming more popular to use an extended handguard over a low profile gas block on AR-15s. Along with this trend has come a need for rail mounted front sights. Rail mounted front sights are not unique. Many companies like Troy and MI already make similar items.
What makes this one unique is that the elevation adjustment without tools! You no longer need special tools or to struggle with a bullet tip to dial your elevation at the front sight. You can simple turn the low profile dial to adjust the front sight up or down. The dial also appears to be shielded to minimize the chances of losing your zero to an impact or snag on the dial.
The price is $125 (MSRP) which is comparable to other folding rail mounted front sights.
