accuracy ??? front sight mounted on rail.

any issues with this setup?
i’d like to do a 10" rail, a 12 o clock light, and a fixed front sight mounted on the rail. probably a Daniel Defense rail…
will this suffer from a wandering zero?

Not if you use a decent rail, and DD definitely falls under that category.

cool…
i’ll put a red dot on it eventually… but those things are $$$
i kinda like shooting irons anyway.
