Is a 20-round fixed magazine prohibited?
It has always been assumed that any size fixed magazine was acceptable to ATF. However, ATF has recently taken to saying that “SKS rifles capable of accepting ‘large capacity ammunition feeding devices’ are prohibited from importation.” Therefore, modifying an SKS to use fixed high-capacity magazine is currently also a violation of 922(r). For more information, check out the discussion on the legality of fixed high-capacity magazines on the Survivor’s SKS Boards web site. Warning: It is unclear exactly when these restrictions on High-capacity Fixed magazines came into effect. This FAQ will assume that since 1998 it is a 922(r) violation to modify an imported SKS Carbine to use one.
