DDC anodize M4 feed ramps
Reviewed on April 29, 2026Verified with Build

Geisseles Super Duty upper has the right combination of M4 feed ramps, properly cut barrel extension shelf, and the DDC color was the whole reason I bought it. Matches their handguards exactly. Forging is clean, no tooling marks visible. Worth the premium over a basic forged upper.
