New weapon

[CathodeRayTube]

LMG:

• Damage: 30 (4-shot kill)
  
• Attackdelay: 150 ms
  
• Reload: 2900 ms
  
• Ammo: 45 magsize, 90 base, 135 max
  
• Spread: Similar to SMG, probably less
  
• Recoil: Similar to AR, maybe more (?)
  

Probably not perfectly balanced, but an attempt.

LMG? why not just MGs. 100 bullets per round and 200 bullets in total

Because, assuming you use those stats, you can hold the trigger for 13 seconds straight. 100 bullets would be close to 30 seconds, and that'd just be overkill.

45 is significant enough to have a "big clip" feeling, while still staying in range with the other weapons

Like I suggested, make the thing overheat/jam if the burst is too long (e.g. at 15 rounds per second, make it overheat after 3-4 seconds, and provide a large clip).
