Light, slim, effective, awesome for the price - Leapers UTG Top Mounted Deployable Iron Sight

I bought a set of front/rear sights just for a handy option for having those very classic and versatile A2 style sights for at least one of my rifles, and honestly I really like these.
They are very light and slim, and the flush screw for attaching is WAY preferred compared to the huge knobs on other sights like the milspec.

The only possible downside is be careful about over tightening the screws. They can get pretty darn stuck. Maybe oil/clean up the threads a bit first. Or just never remove them. I had to fight with my torx set to loosen these up once torqued down.

All considered, these are awesome.
