We carry a huge selection of upper receivers for your next AR-15, AR-10, AR-9 and everything in between. The upper receivers sold by Click-Click-Boom are uppers we’d put on our own firearms. We carry the biggest brands on the market. Your upper ends up taking the biggest beating overall from firing. That’s why it’s important to buy a quality upper the first time so you don’t have to revisit later.
The uppers below are considered stripped uppers, meaning they won’t come as a complete upper with the barrel, handguard, or bolt. Just the metal upper receiver portion, and occasionally a dust cover and forward assist. Some of the AR uppers below will be side charging upper receivers. These require a different type of bolt carrier and charging handle than a standard AR-15. Be sure to check your build before buying your next upper.
