Very Nice with or without color...

Very nice lower looks great with or without paint, but a little color fill and paint takes it over the top.. The only issue I've had is with the 60rd drum mag it won't fit unfortunately if the drum mag was 1/2 longer, it would work, but other than that, it's awesome...

Just the sight of it gives you the creeps!!! (in a good way). Awesome looking! Great detail! Definitely superior material! Way worth it!! Definitely will buy another.
