So I've searched through the forum quite a bit, and I've seen this question asked inside of a post, but never answered. Does a carbon fiber wrapped barrel meet the MDSP criteria for HBAR? The ones I've looked at have the same OD throughout the barrel, but of course are not stamped HBAR or advertised as one. Currently in the middle of a semi-lightweight build and don't want to shell out the money for one if they're not legal here.
