need advice for iron sights

[rebrousse_poil]

I ordered a benchmark barrel and would like to put iron sight on it. It will be a #4 contour fin 24 ish. What kind of iron sights should I buy and what height (front and rear)? I really like the Tikka sights (with the front hood) and wonder if they could fit on the barrel?
