Rainier Arms (http://www.rainierarms.com) finally has some of their new Nickel Boron Thunder Bolt Carriers (http://www.rainierarms.com/?page=shop/detail&product_id=3651) available. These were originally expected several months ago, but due to the panic, they were pushed back. They are currently sold out online, but I hear they have a limited number on hand for in-store walk ins. Best to check with them prior to making the trip.

The bolts are HPT & MPI tested & Marked to give you ultimate confidence in your weapon system.
