I called Colt’s Customer Service and talked to a guy named Steve. Colt sent out a handful of Anacondas with the new optional rail to a handful of select media writers as part of the review and evaluation process. The new rail for the Anaconda will only be available through Midway USA and Brownells. The rail should be available for purchase by the end of Summer or early Fall. I directly asked for a specific date, but I was not given any dates. I asked if a pre-order could be done and was told not at this time. When I called both Midway USA and Brownells, both companies are aware of the new Anaconda ramp, but can’t take any order/pre-order because Colt has not gave the part number yet. No other updates on the brass bead front sights or prices for the new mount either. I guess we will have to stay tuned and keep checking back to Midway USA and Brownells at this time
