Some States have length requirements for carbines and rifles, the HTA Bullpup stock with carbine installed is too short. So in these states the law requires you to lengthen the barrel with something pinned in place. If you pin something to the barrel you cannot breakdown your HTA bullpup to clean it or repair it. So I just added to the butt stock to make the overall length of the gun the required length.
