A handguard or other cover for a firearm includes a shell or body with a hollow interior cavity and a retaining structure configured to engage the forearm and retain the shell in place on the forearm, where the retaining structure is releasable to permit removal of the shell from the forearm. The shell extends between first and second edges around an angular range greater than 180° and less than 360° to define the shell in a semi-tubular shape or a C-shape. The shell may have a concave inner surface and a convex outer surface extending between the first and second edges. The first edge is spaced from the second edge to define a gap providing access to the interior cavity, and the shell is configured to be connected to a forearm for the firearm by inserting the forearm within the interior cavity.
