The Twang Buster from DoubleStar is an accurately named part that removes the annoying “twang” from the buffer tube. Historically known in rifle length tubes, the Twang Buster goes on the opposite end of the buffer spring to provide a sound dampener for the rear of your firearm. Just snap it in and no more twang. It’s the part you didn’t know you needed and will change the way you feel about firing your AR. Order yours now!
*Depending on QC, some collapsible buffer tubes are slightly shallower which will not allow the bolt to lock to the rear when Twang Buster is installed. This part was designed to work with RIFLE BUFFER TUBES. It will work with most collapsible tubes, but not all.
