To answer a couple of questions:
We will be working on the schedule for MAX-11A1/15 and MAX-10/15 production when we get back from New Years shut down. We are closed for the rest of this week fir Christmas and will be open a couple of days next week.
A limiting factor for production will probably be availability of Barrels and AR Bolt Heads. Barrels currently have a 6 month lead time. They are currently on order.
Just like the MAX-11/15, the uppers will be available with one barrel length, 10-1/2". It is a standard AR barrel, so changing it out is fairly simple. For logistics, we only offer one barrel. It maximizes our throughput.
The first batch will be 20 each and then batches of 50 each. Until we work out deliveries for the AR parts, we cannot estimate how long it will take for each batch.
If we are lucky enough to receive parts on time and produce at the rate we did for the MAX-11/15, the lists should be knocked out in about 6 to 8 months.
