I don't know about you guys, but I find the irons hard to use for long range. They are fine for short-med
I find the irons difficult without silencer when you're talking long range kills, as they don't work well with muzzle flash when it comes to staying on a moving target at long range. But with silencer the irons are amongst the best in the game in my opinion.
I love this gun with stock, suppressor and fast mags (and Toughness perk).
