Slacker, you can order them from Jon (That Guy) direct. Re: options, we're thinking of the following, it's structured in a manner to take price into consideration:
1. Single lever with end cap
2. Two levers
3. Three levers

With the free lever exchange program, there's no need to purchase the 3 lever kit

The 2 lever kit will become standard for the .223/.308 model this year as well.
