Swiss Arms Black Special information

[stefofthenorth]

Does any one know if it is possible to find out twist rate and date of manufacture for a Swiss Arms Black Special.

I don’t think it’s much help but it is possible to “measure” twist rate.

Date of manufacture is sometimes on the left side of the receiver and on the bolt carrier. It will look like an NB with a 2 figure number. The twist rate usually corresponds to the muzzle geometry. The 1/10 is shorter and does not have threading inside the muzzle and the 1/7 is longer with the internal threading. There's someone who can probably chime in and give you more info than I.
