I started using the dragonov for the first time yesterday,and had a blast. I used,BE,Hardline and stalker,as i had it equipped with an ACOG scope.

The Sniper Rifles you should be using are either the Dragonuv or MSR. The MSR is more powerful, but the Dragonuv is better for spamming and it's very accurate now. A little tip since you're using 'Overkill', use the G36C. I know that you want to use the ACR as your secondary, but the G36C has a faster swap time than most weapons in the game (except the Five Seven, which only raises faster). Next, use 'Speed'. You'll have a rifle in your hands, but you'll move at the speed of an SMG. However, I won't deny that 'Kick isn't a bad choice either (for the Dragonuv). Despite that I recommend using the G36C for fast swapping, I think that Sleight of Hand Pro is still a good choice. If you're OK with the switch speeds then go with Blind Eye. For your third perk, you either want Marksman, Sitrep (if you have a headset), or Steady Aim (I don't completely recommend it, but it's there for those moments where you get caught in CQC with the Sniper Rifle out). Equipment is completely your choice. For attachments, I'd recommend using either the Silencer, Ext. Mags, or the Variable Scope on the Dragonuv (Ext. Mags and V-Zoom for MSR), and for the G36C I'd recommend either using Red Dot with 'Kick' or Red Dot with Ext. Mags via 'Attachments' (if you can control the strong vertical recoil or learn to burst fire it). You're 'Strike Package' should be determined by your play style with the Sniper Rifles. That's all I can really tell you.

I'm another dude who's gonna proclaim their love of the RSASS but I thought i'd float the silencer and vari scope setup. It's perfect for the smaller maps and lets you work at all ranges giving a good increase to the spots you can just drop and shoot plus with the lowest zoom it lets you work up close much like an ACOG freeing you up to carry a launcher/ machine pistol also letting you use QD or assassin.

it's crazy

MSR or L118A is the best and only ones to use they get less hitmarkers (meaning more one shot kills) than the overrated 50cal and you can run with them pretty fast.the rest of the sniper guns are weak and a joke. use the zoom scope after you unlock it the stock scopes are too zoomed in also use either focus or impact. if you are gonna run around a lot i would say use overkill (mp7 or pp90m1), steady aim and quickdraw. if you are gonna lay around hardscopeing use blindeye,assassin and marksman. lethal c4 is beast after you learn to use it double tap (fast) square to make it explode quicker also blow it up before it hits the ground or a wall the blast is 3x greater. use a portiable radar or trophy system if you gonna lay around or use flashbang if if you gonna be moving around.  I run n gun with my MSR/L118A this is how i set it up . Primary MSR or L118A with impact and v. zoom scope, Secondary MP7 or PP90M1 with range and rapid fire. Lethal C4 EVERYTIME, tactical i mix it up with a portiable radar and flashbang. Percs, Slight of hand pro, overkill pro and steady aim pro. deathstreat (its rare i get rewarded these) i use juiced. killstreaks i use Predator missile, chopper and ac130.  NEVER USE A SUPPRESSOR they make sniping pointless you gotta shoot em 2 and a lot of times 3 time to kill em
