Manufacturer claim
- The Bolt Series is rated to 500 F.
- Stealth Project publishes 27.5 dB of sound reduction for the Bolt 5.56.
- Stealth Project's caliber compatibility chart rates the Bolt 5.56 for .17 HMR through .224 Valkyrie, including .22 Long Rifle, 5.56 NATO, 5.7x28mm, .220 Swift, .22-250 Remington, .223 Remington and .223 WSSM.
- Stealth Project suppressors use a patented canted helical design in place of conventional baffles, with a single attenuation chamber to control muzzle blast.

- The baffle-less design eliminates the chance of a baffle strike; Stealth Project states there are no baffle strikes, ever.
- The design is self-tightening: force from high pressure gas on the canted helix creates a rotational force that tightens the suppressor.
- Stealth Project states first round flash is eliminated near 100%, because combustive ambient air is retained in the attenuation chamber rather than escaping through the muzzle before combustion.
- The Bolt suppressors use Accelerated Gas Technology to keep the suppressor cleaner and quieter, and take caliber inserts to reduce wear.
- Point of impact shift is minimized from unsuppressed to suppressed shooting in the field.
- The Bolt 5.56 is direct thread, 1/2x28.
- The Bolt Series is Stealth Project's helical aluminum series of suppressors.
- The one piece core has no welds to fail and no multiple baffle chambers, so the system heats evenly along its entire length with no hot spots.
- Stealth Project lists its suppressors as user serviceable.
- Stealth Project designed the Bolt Series for the hunter: ultra lightweight, shorter in length with larger volume, and maximized recoil reduction, primarily for hunting and precision shooting applications.
- The Bolt Series is only available in Direct Thread.
- Stealth Project's caliber compatibility chart specifies a minimum 16 inch barrel for the Bolt 5.56.
