If memory serves me right they used to stamp them with MAG or an M in the serial number ? I ordered a new one, Last November, and waited 12 months, it arrived on the 14th. In the mean time, I bought a used one, that is only stamped 2 3/4 in. The new one is stamped 2 3/4 or 3 inch. ' I am offering it for sale, and was ask if its a MAG ? Do they no longer offer it with wood stocks as a MAG ? Looking at Remington's web sight, I only see MAG's offered in the Express models, with up to 3 1/2 inch shells. Does the new ones, receivers handle shooting 3 inch shells consistently ?
