Fitment help is based on the information you enter and on manufacturer and published data. Parts, barrels, optics and receivers vary by maker, model and production year, so always confirm dimensions, thread pitch and clearances with the manufacturer or with us before you order. If we do not have verified data for your exact setup, we will say so rather than guess. This is not legal advice, and state and local rules vary.
