My interpretation, which may be entirely incorrect, was that in order to qualify as a "pistol" and therefore be eligible for use with the then legal brace, it had to be under 26". I wouldn't think that there would be a minimum or maximum length for an SBR, only that with a barrel less than 16" it would be an SBR, unless it met criteria for a pistol? (See what I did there @OkieStubble?)
