New 1301 Tactical Marine features the addition of several integral improvements in response to feedback from the marketplace. We have redesigned the bolt release lever to allow for a more solid function and eliminating the chance of a double feed. We have also added an aluminum picatinny rail on the receiver in order to support heavier optics. Lastly we have threaded the barrel for Optima Bore HP Chokes which will allow for you to use any of our 12ga OBHP chokes to get the most performance out of your 1301 Tactical. The Marine edition features a high visibility corrosion resistant finish and Aqua-Tech coating ideal for maritime environments. - Barrel length (in): 18.5 - Chamber (in): 3 - Choke: OCHP - Gauge: 12 - Lylium: Y - Overall length (in): 37.8 - Receiver: Aluminum
