12 inches is a normal barrel length. Longer barrels like 14 and 16 inches don't mean accuracy. For you they may mean a sighting aide but for me they mean an aluminum tube batting against the bunker I am standing behind for cover. CCM Doesn't offer longer stock barrels but if you bought a T2 that with the body insert system it would give you a longer overall length (around 14 inches).
