I have about 250 drops in my sniper hunches and they are an absolute blast. They require a very strange loadout and you have to get used to using them, but once you do, they are absolutely hated by the opfor. I'll give you my design tips below.
Right up front, let me say that these mechs are not good as brawlers and are pretty useless against a light. You must be a good shot, and you MUST choose your locations carefully. I agree with posters above that the zoom module is of little use. The image is very blurry and not much of an improvement in real terms. For the price and xp, it should be 5x or better and the image should be crystal clear. One more note, speed is key. You need to be able to run away from a brawl and reposition quickly, so drop in as big an engine as reason and resources allow.
The tactic you'll employ is to just pop your head and the gun pod above a ridgeline. I suggest using thermal imaging at all times. These are DPS snipers, so staying on target is important. They are also useful to suppress and pin down an enemy, so don't worry so much about kills. Just chew through armor and make them keep their heads down. If your team is even marginal, they'll use this advantage to approach the opfor. These designs are also effective counters against ecm.
With that out of the way, let's move on to the builds. I use the 4p and the 4g for this role. I've tried just about every possible weapons combination and here's what is best. In both these builds I'm putting all or most of the weapons in the torso gun pod. I know that sounds a bit mental, but it's great as you just have to put the guns and your head into view. The other advantage in doing this is that there are no convergence issues as all the guns are along the same axis.
For the 4p, I put 3ERLL in the torso and that's it. I keep them on chain fire, so I can manage their heat. DPS is less than 7, but your alpha is 27. The key is to keep them steady, so they do damage to a single location. Headshots are not uncommon and they're very useful for knocking the ears off a cat.
I like the 4p, but the 4g is way more fun and even more crazy. I put 2xAC/2 plus an AC/5 in the torso and back that up with a medlas on the right arm. The medlas is just there for killing blows or to swat away a light. I carry about 9 tons of total ammo. I do not use these in chain fire. The greatest difficulty with this build is that the AC/2 and AC/5 rounds travel at different speeds and have different cooldowns (.5 and 1.7 respectively), making it difficult to put all rounds on target. Yes, your alpha is terrible at 14, and the ACs just do 9, but your DPS for just the ACs is 11, and that's a bunch. For example, that's higher than a twin AC/20 cat. You're up in LRM/20 territory assuming all the missles hit. I know that alpha sounds bad, but I have killed charging, undamaged Atlases several times simply by chewing throught their CT or head. If it takes 6 or 7 seconds for them to charge you, that's 60 to 80 points of damage. That's twin gauss, twin ac/20 territory from a 50ton mech.
Ok, a few notes before I close. Both of these mechs can have heat problems, but they are not serious. I run DHS in both and I can run on Caustic with no problem. Obviously the 3xERLL are the bigger issue and thus the reason for chain fire. The trick with sniping is that you often have several seconds between shots and during repositioning, so you can use that time to bleed off heat. Speaking of repositioning, do it, and do it often. These builds get you noticed because they're both very annoying. You will find that people will ignore an Atlas and focus on you because of the whap, whap, whap upside their head. If you keep poping up in the same place or, worse, stay still you will die very quickly. That said, it's a hoot to stand at a ridgeline and shoot people while counter fire impacts the dirt all around you. Friendly ECM is also very useful to you, so stand near a DDC if possible. Because of your minimal exposure and the reduced sensor range, they may not even know you're there until it's too late. Finally, I typically use adv sensor range and adv target info modules.
Good hunting!
