There is no definitive answer to this question since there are variations in the design of AR-15 lower receivers. Generally speaking, however, most AR-15 lower receivers are roughly 7 inches long. There can be some variation in this measurement depending on the specific design of the receiver, but typically they range from 6.75 inches to 7.5 inches in length. So, if you’re looking for a general answer, most AR-15 lower receivers are between 7 inches and 7.5 inches long. However, it’s always best to double-check the specific dimensions of the receiver you’re interested in to be sure. Thanks for asking!
