To manufacture a suppressor, a class 7 or class 10 license is needed plus the SOT which has a minimum cost and a sliding cost based upon total $$$ revenue. The materials used in a quality suppressor are generally more expensive than steel due to a size/weight ratio. The baffles are hit by gas jets as it reduces the pressure before the bullet exits the muzzle, this requires different metallurgy than barrels. Finally, silencers are an art and a science, you can do all of the calculations and not get the results expected -- some small changes make significant differences.
