Any combination like railgun with carbine scope and suppressor
Glitch weapons, eh? I’ve got two that stick out in my mind:
- Arclight + Spartan Laser - Sentinel BR / DMR + Railgun or Sentinel Beam
DMR and Prophets Bane
The smg with the promthean barrel is pretty sick to me but theres a lot 
Here’s a couple that I have created with the weapons glitch
Physical Weapon + Glitched Weapon Properties
Safeguard Sentinel Beam + Blood of Suban (Needle Minigun)
Safeguard Sentinel Beam + Pro Pipe (Fireworks)
Boltshot + Oathsworn (Pocket Shotgun)
Assault Rifle + Appetite for Destruction (Assault Rifle with 108 magazine size extended Clip)
