D.C. Mun. Regs. r. 24-2324
Section 101 Paragraph 3A of the Act (D.C. Official Code § 7-2501.01(3A) (2013 Supp.)) defined the term "assault weapon" and § 202(a)(6) of the Act (D.C. Official Code § 7-2502.02(a)(6) (2013 Supp.)) declared that an "assault weapon" may not be registered in the District.
In those instances where the definition of "assault weapon" refers to a firearms manufacturer or description without including a specific model reference, the term "assault weapon" shall be interpreted to include only those firearms produced by such manufacturer, or possessing such description, that share characteristics similar to the firearms enumerated in § 101 Paragraph 3A(A)(i)(I) through (III) of the Act (D.C. Official Code § 7-2501.01(3A)(A)(i)(I) through (III) (2013 Supp.)), or possess any of the enumerated characteristics listed in § 101 Paragraph 3A(A)(i)(IV) through (VIII) and 3A(A)(ii) through (iii) of the Act (D.C. Official Code § 7-2501.01(3A)(A)(i)(IV) through (VIII) and (3A)(A)(ii) through (iii) (2013 Supp.)).
A firearm that is produced by a manufacturer or possesses a description that is included in the definition of "assault weapon" referred to in § 2324.1, but which does not share characteristics similar to the enumerated firearms or the enumerated characteristics described in § 2324.2, may be registered; provided, that the firearm is not otherwise prohibited from registration under District or Federal law or regulation.
