Overview

Nordic's +3B MXT kit is the published flush-length tube geometry for an 18.5-inch Benelli M1 or M2. The current kit is 8.35 inches long and includes the extension tube, cap, and full-length spring. It still cannot mount to an M2 without NUT-BN-12-00. This guide also pairs it with BCL-12 to keep the barrel and extended tube supported as one system. Final shell count varies with shell length and the gun's original magazine configuration.
