MR556 A4 compatibility and related handguards
Model name and length alone do not confirm fitment with every upper assembly, production variation, or altered configuration. Confirm the SKU, mounting interface, clearances, and manufacturer documentation.

Identification considerations
Check the SKU, model suffix, nominal length, mounting features, and current upper-receiver configuration. Similar-looking rails from other model families are not automatically interchangeable.
Safety and professional service
Unload the firearm, remove the magazine, and verify the chamber is clear. Handguard removal or installation can affect fit, clearances, and mounted equipment; use a qualified gunsmith and follow the manufacturer’s manual.
