Identification considerations
Confirm the MP5 .22 LR Rifle marking, 16.1-inch barrel, rimfire caliber, stock configuration and factory package ID. Use receiver markings, caliber markings, serial-number records, packaging labels and the current operator manual together rather than relying on photographs alone.
Compatibility information
Magazines, bolts, barrels, stocks, handguards and internal components should be treated as model-specific. Do not assume that parts for centerfire G36, HK416, MR556, MP5 or SP5 platforms fit these rimfire models. Confirm the exact manufacturer part number before use.
Safety, lawful transfer and professional service
Treat every firearm as loaded, keep it pointed in a safe direction, keep your finger away from the trigger until ready to fire, and follow the current operator manual. Possession, transfer, transport and storage must comply with applicable law. Inspection, repair and parts installation should be performed by the manufacturer or a qualified firearms professional.
