Great offset flip-up sights - Ultradyne C4 Offset Flip-Up Front/Rear Sight Set

I have many off-set sights on AR platforms; but these are Number 1 on my list. Can hit targets well beyond 150 yards consistently with excellent front sight (circle) alignment within rear sight (circle) alignment. For long range shooting, these sights are much easier than trying to align a front sight post. When shooting short range targets, aligning the lower half of front sight (circle) with rear sight works.
In essence, the Ultradyne C4 Offset Flip-Up Front/Rear Sight Set is worth the money.
