On the off chance that anyone that bought an M4 would rather have an Airmarksman Backbone instead of the factory FX Top Rail I'd be interested in a straight up trade..
The Backbone I have is the long version in Black in perfect condition. Let me know if you're interested... but I won't hold my breath
