Distinct from simple shoulder stock kits, full carbine conversion kits are not classified as short-barreled rifles. By replacing the pistol barrel with one at least in length and having an overall length of at least , a carbine converted pistol may be treated as a standard rifle under Title I of the Gun Control Act of 1968 (GCA). However, certain "Broomhandle" Mauser C96, Luger, and Browning Hi-Power Curio & Relic pistols with their originally issued stock attached only may retain their pistol classification.
