Jason169, you can use the Express fully rifled and cantilevered barrel on your wingmaster. They fit just fine. The finish isn't as nice on the express barrels as they were on the wingmaster but they function very well. If you aren't planning on mounting a scope then just get the one with rifle sights. They are anywhere from 50 to 90 bucks cheaper than the cantilevered anyway. At least they are at midway.
