Airsoft adjustable iron sights on a NC22 upper?

[sierra77mk]

I bought the NC22 upper and have a scope to practice for 3gun shooting.

I would like to use iron sights on it from time to time to practice highpower but I have a budget too.

I thought I might use airsoft sights but know nothing about them.

Since the upper does not need a gas block, a clamp on front sight base and a carry handle or LMT type of BUIS is what I would want.

In pricing this out, I could do this for less than half the price of Yankee Hill or comparable iron sights.

Is airsoft stuff able to stand up to rimfire use?

What are the clicks worth on airsoft rear sights?

Is airsoft stuff able to handle and keep click adjustments on a rear sight?
