This is not a comprehensive list. Some of my builds may not be optimal since I just threw these together in the mech lab because I was bored, but they're close.
Clan Long Range Mechs -
HBK-IIC-A (4 ERLL):
https://mwo.smurfy-n...3de5dffbd5dbce6 Very long range, great punch for it's weight. A bit of a glass cannon, but still deadly.
HBR (4 ERLL):
https://mwo.smurfy-n...ff9e597d8a2ad88 Same build as the hunchback, but 15 tons heavier. For those tons it gets more armor and ECM, but loses jump jets. I generally think the hunchie is better in this role.
HBK-IIC-A (2 ERPPC):
https://mwo.smurfy-n...2c856078618e445 Another long range hunchie... this time with ER-PPC's! It's a very versatile mech. You can drop the ER Smalls and a heatsink or two for a TCOMP if you want to get better velocity.
SMN (2 ERPPC):
https://mwo.smurfy-n...46d98e120ec4fea A staple clan mech... ER-PPC summoner. Very good poptart mech. The HBK-IIC can do the same thing though at 20 tons lighter.
NTG (2 ERLL + 2 Gauss):
https://mwo.smurfy-n...3781e05847e2215 Night Gyr is a tough mech to play, but it's got some powerful long range ability. 2 ER large + 2 Gauss is deadly if you can get used to this mech's slow speeds. It handles like an assault mech, but doesn't have the armor of one.
WHK-PRIME (4 ERPPC):
https://mwo.smurfy-n...1eff8b5c4d37083 4 PPC Warhawk. Really fun mech to play, can do a LOT of damage from very long range. Nearly the stock configuration too, so not much extra to buy on it.
Inner Sphere Long Range Mechs -
BSW-X1 (3x AC5)
https://mwo.smurfy-n...c2fe65a528dc2e2 Maybe not "super" long range, but it's one of my favorites to play. Unexpectedly good DPS from ~600-700 meters out.
BSW-X1 (2x Light Gauss)
https://mwo.smurfy-n...08113f73c7a28aa Twist on the above build... I've been playing with it, and it is doing better than I thought it would. Maybe one of the few light gauss builds out there I've tried that I actually liked.
TDR-5SS (5x ERLL)
https://mwo.smurfy-n...d1d668a7971d4ce Runs hot, and is dangerous with the XL engine, but packs a hell of a long range punch. I use one in my long range faction play deck, it serves me quite well. Maybe tone it down to 4 ERLL and put a light engine in it if you want a cooler, more survivable mech.
WHM-6R (4x ERML, 2x Gauss)
https://mwo.smurfy-n...f030e8d2397f99a The "Gausshammer" build... one of the best mechs in the inner sphere. Great damage, good agility, decent speed. My most played mech in faction play.
BLR-1G (5 ERLL)
https://mwo.smurfy-n...4e141271363a3bc The best long range sniper mech in the inner sphere. Very high mounts, very long range, decent hitboxes. Builds vary for it, but I like using the LFE350 and a bigger targetting computer to get the most range possible.
ANH-2A (6 AC2)
https://mwo.smurfy-n...14c6ca3cf7e0d6c If you're good at landing shots on target at range, this thing is a monster. Started using it more after solaris, but in terms of just laying fire down range, this thing is unbeatable.
