The OPL-40M (Vietnamese: Ống Phóng Lựu 40mm), also known as the SPL-40 (Vietnamese: Súng Phóng Lựu 40mm, lit. '40mm Grenade Launching Gun'; the same designation can also be confusingly used for the Vietnamese production of M79), is an under-barrel grenade launcher (UBGL) developed by the Z111 Factory in Thanh Hóa, Vietnam.
History
The OPL-40M was developed and produced by Z125 Factory of General Department of Defence Industry.
The OPL-40M was first shown in the Indo Defence 2018 exhibit[2] which represents a step forward in Vietnam's effort to localize its defense industry.[3]
Design
The OPL-40M is chambered in standard 40×46mm NATO rounds, enabling compatibility with international ammunition standards. Its design draws inspiration from the M203 (USA), GL40 (Israel), and GP-25 (Russia),[3]integrating the advantages of these systems to meet the operational requirements of the Vietnamese military.
The OPL-40M is designed to be mounted under assault rifles, including Kalashnikov rifles and STV rifles - Vietnam’s new standard service rifles based on the Israeli Galil ACE platform.[1] This grenade launcher can be mounted under the STV-380 using the STV-380’s picatinny rail and bayonet lug.
The OPL-40M uses a forward-sliding and tilting barrel mechanism, allowing for the loading of longer grenade rounds.[4][5][6]
Adoption
The OPL-40M is a domestically produced launcher intended to replace earlier imported grenade launchers such as the M79 (produced locally as the SPL40),[7] and other foreign designs like the M203 and GP-25.
