NOTE : Calibers are approved based on suppressor caliber, not suppressor length. For example, a Plain 30cal Short and 30cal Long have the same caliber and barrel length restrictions.
Barrel length restrictions apply across all suppressors regardless of the caliber of the suppressor. For example, a Plain 9mm can be used with 5.56mm, however, it still retains the 10.5in barrel restriction.
This list will change and grow as we can test with new calibers. If you have any questions, please contact us.
