LBCs are a good way to break "customizer's block" and get the creative juices flowing. It's always nice to find a use for parts that go together well with minimal effort, and when you can make a quick batch of them it's even better. Here, only the neck needed to be drilled out a bit, and the rest came together quite seamlessly.
I see COBRA Bagmen as being utilized alongside Dreadnoks for small criminal operations to generate quick capital for larger operations. They're usually given a crash course in urban combat and intimidation tactics by Firely, and sent on their way with minimal investment in training and equipment. Those who are successful and show enough raw talent are often promoted into the Alley Vipers.
