Frequently Asked Questions

What are the primary design goals of the Exigent Defense Fire Team 5.56 suppressor?

The primary design goals for the Fire Team 5.56 suppressor were sound suppression and flash signature reduction. Low back pressure was considered a tertiary, though still desired, feature, reflecting a prioritization of signature management over minimizing gas blowback.

How is the Exigent Defense Fire Team 5.56 suppressor constructed and what are its key specifications?

The Fire Team 5.56 is constructed using Direct Metal Laser Sintering (DMLS) 3D printing with Inconel. It weighs 14.2 oz, measures 5.75 inches in length without the mount, and is rated for barrels 10.3 inches or longer, offering 32 decibels of sound reduction.

What features contribute to the sound and flash signature reduction of the Fire Team 5.56 suppressor?

Signature reduction is achieved through unique blast chamber baffling, forward venting gas holes (six square holes), and an integrated counter-rotation flash hider with diamond-shaped features. These elements manage gas flow and bullet interaction to minimize visible and audible output.

How does the Exigent Defense Fire Team 5.56 suppressor perform in terms of recoil management and return to zero?

The suppressor significantly aids in recoil management, providing a soft rearward push and consistent performance with minimal muzzle rise. Testing demonstrated a good return to zero after removal and reattachment, indicating reliable mounting and consistent performance.
