Manufacturer claim
- EOTECH lists the DCBL 556 as Not Rated for full auto, and its warranty excludes damage related to full-auto firing.
- EOTECH publishes a dB rating of 133.6 for the DCBL 556.
- EOTECH publishes both a suppressor-body figure and a with-hub-and-flash-hider figure because the industry follows no standard: some makers publish the body weight alone and leave out components that are required to use the suppressor.
- EOTECH's Vent-Forward design vents gas forward, away from the shooter, which it says cuts back pressure and the blowback of gas and fumes into the shooter's face on semi-automatic hosts, for smoother cycling and less carbon buildup.

- 3D printing lets EOTECH build internal baffle geometry that could not be machined conventionally, which it credits for the sound reduction, the lower weight and the improved gas flow.
- The DCBL 556 uses the industry-standard HUB thread pitch of 1.375"-24. EOTECH states that any HUB adapter, including other companies', will mate with it.
- EOTECH publishes a bore diameter of 0.283" and an overall diameter of 1.75" (44.5 mm) for the DCBL 556, with a published maximum cartridge of .22 Creedmoor.
- Per the DCBL manual, the hub threads onto the suppressor body counter-clockwise and torques to roughly 35 ft/lbs with an armorer's tool; the KFM flash hider goes on the barrel at roughly 30 ft/lbs and the suppressor tightens onto it hand-tight, roughly 20 ft/lbs. The KFM adapter uses reverse threads, so removal turns clockwise.
- The DCBL 556 is a monolithic Grade 5 titanium body 3D printed from titanium powder, treated with a high-temp Cerakote finish and offered in matte black or tan.
- Residual titanium powder from the 3D-printing process makes a new DCBL spark on the first rounds fired; EOTECH says this drops off sharply after roughly 200 rounds and is a harmless byproduct of the material.
- EOTECH covers the DCBL line with its NoBS Lifetime Warranty: it will repair or replace any issue related to materials and workmanship free of charge, for the original registered owner.
- EOTECH says the monolithic, corrosion-resistant construction is built for harsh environments including salt air, extreme temperatures and prolonged courses of fire, and that the greater mass acts as a heat sink while thicker walls resist warping and erosion.
- The DCBL manual states the suppressors are manufactured in the USA and licensed by EOTECH for sale within the USA only.
- EOTECH considers its rifle suppressors self-cleaning under the high pressure of firing; it recommends inspection for wear and an ultrasonic cleaning every 2,500-3,000 rounds rather than routine user cleaning.
- The DCBL 556 ships with a hub and a KFM flash hider. EOTECH publishes the suppressor body at 7.1" (180.4 mm) / 13.7 oz (387 g) and the assembled suppressor with hub and flash hider at 7.9" (200.7 mm) / 19.6 oz (554 g).
- EOTECH publishes a minimum barrel length of 10.3" for the DCBL 556.
