Everyone will say hidden hand and unflinching are must haves (and it's true) the scope and middle perks are preference. For scopes you want either Ambush: people tend to love this scope because it adds stability but it's hidden perk is it decreases aim assist Shortgaze: by far my favorite scope as it caters to my close quarters sniping and adds about 30 aim assist Long view slr10: this is the most underrated yet one of the best all around scopes. It has the highest added aim assist at 40 and slightly more zoom at 5 than the other two which are at 4.5. This is my second favorite scope and lots of people don't even know about it because they see the name and assume it's a long range scope. It's not to be mixed up wit the Long View slr20 which is indeed a long range scope. Now for the middle perk for me it's a toss up between handlaid stock and snapshot. I prefer snapshot for things like trials, skirmish or rumble because you need to aim in as fast as possible in the quick pace play. If I'm playing control or clash handlaid stock is preferable so I can kill more than one enemy without the kick of the rifle making me lose sight of where one shooting. The nice thing about these perks is you can get both and switch between since handlaid stock seems to fall a lot so if you get snapshot there's a great chance you got handlaid as well. Also a point should be made that if you run ambush scope with handlaid stock it almost maxes out your stability and makes follow up shots super easy.
