Novel noise suppressors to attach to firearms designed to minimize weight, maintain strength, increase accuracy, and improve usability. Disclosed embodiments include a blast chamber designed to withstand greater internal pressures than other suppressor components; a first baffle and spacer formed as a single component and subsequent baffles and spacers formed from separate components; a first baffle comprising a substantially semi-hemispherical dome and subsequent baffles comprising a substantially conical shape; and exterior bi-directional flutes formed on the exterior surface of the suppressor.
