Rainbow Six Siege – Best Barrel Attachments

These are the best barrel attachments (in my opinion). Every gun was tested with angled grip (if available) and the highest magnification possible, 10 meters away from a wall.

I love two things in life, games and sports. Although sports were my earliest interest, it was video games that got me completely addicted (in a good way). My first game was Crash Bandicoot (PS1) from the legendary studio Naughty Dog back in 1996. I turned my passion for gaming into a job back in 2019 when I transformed my geek blog (Re-actor) into the gaming website it is today.


  1. It turns out I’ve been playing Wong all these years, although I still manage to get 1.0 ratio or a slight beyter for kills.
    Using the correct attachments gave me immediate confidence and has allowed the game to be funner. Thanks for the article and recommendations.
