	~~The~~ China Lake ~~pump-action~~ grenade launcher ~~or NATIC~~ is a pump-action grenade launcher ~~that was~~ developed ~~by the~~ Special ~~Projects Division of~~ the ~~Naval Air Weapons Station China Lake, which provided equipment to [[United States]] Navy SEALs~~.		'''China Lake grenade launcher''' (often called the “China Lake pump”) is a U.S.-made pump-action 40×46mm grenade launcher developed for Naval Special Warfare use during the Vietnam War. It uses a tubular magazine holding three grenades, plus one in the chamber, allowing four shots in rapid succession before reloading. It is best known for its very limited production and its association with U.S. Navy SEAL teams as a short-lived attempt to provide repeating 40mm firepower.
	~~=HISTORY=~~
	~~The [[M79]] and [[XM148]] grenade launchers were single-shot, and the repeating T148E1 grenade launcher was unreliable, so~~ a ~~request was made to China Lake engineers. Navy SEAL teams were pleased with the resultant pump-action grenade launcher. The~~ tubular magazine ~~held~~ three ~~40x46mm~~ grenades, ~~and so with~~ one ~~grenade~~ in the chamber, four ~~grenades could be fired rapidly~~ before reloading. ~~In fact, a skilled operator could fire four aimed shots before the first one landed. The grenade launcher was extremely light~~ for its ~~size, since~~ a ~~significant portion of it was made of aluminum~~.

	~~Submitted for field trials in~~ [[~~Vietnam~~]], ~~this weapon apparently performed quite~~ well with HE-~~Frag~~ ammunition.		==HISTORY==
			The weapon was developed at the Naval Weapons Center/Naval Air Weapons Station China Lake as a response to the limitations of single-shot launchers like the [[M79]] and [[XM148]] and the reliability problems of early repeating designs such as the T148E1. China Lake engineers applied pump-action shotgun concepts to a 40mm launcher, producing a compact repeating system that retained M79-like range and accuracy while greatly increasing immediate volume of fire. Reports from the period and later accounts describe it as well-received by some SEAL users and effective with standard HE-fragmentation ammunition in Vietnam.

	~~The pump~~-~~action grenade launcher features leaf iron sights similar~~ to ~~the M79~~. The ~~front sight is a fixed square notch~~. ~~Depending on if~~ the ~~leaf is folded~~ or ~~not~~, the ~~rear square notch is either fixed or adjustable from 75 to 400 m~~ in ~~25 m increments~~.		Sources differ on total production, with estimates commonly ranging from the mid-teens to a few dozen; later Navy-record checks cited by SEAL historian Kevin Dockery are often reported as confirming 22 completed guns. The launcher was never formally standardized with an official U.S. designation, and the names “NATIC” and “EX-41” are frequently described as mistaken or later, unrelated labels. Surviving originals are scarce, with documented examples in museum collections including the National Navy UDT-SEAL Museum and Vietnam’s War Remnants Museum, while others remain in U.S. Navy custody.

	~~The larger screw on~~ the ~~left side~~ of the ~~receiver was designed for a quadrant sight to be mounted~~.		===Sources===

	Sources differ as to how many weapons were produced. One claims that between 20 and 30 were made. However, according to another source, only 16 were made. The highest original receiver number found is 50, but it may never have been made into a functional weapon. SEAL historian Kevin Dockery has confirmed 22 completed guns being carried on Navy records. Only three originals currently remain under US Navy control; the rest have been demilitarized.

	The China Lake Model is sometimes mistakenly referred to as the "EX-41" or as the "China Lake NATIC". The EX-41 was a design prototype created in the mid-1990s based upon the earlier China Lake Model pump 40mm. The EX-41 was only produced as a single prototype as a follow-up design created two decades after the China Lake Model was produced. The China Lake NATIC designation is also erroneous as the weapon was never known by that designation. Since it was made on an ad hoc basis for special operations forces, it was not formally adopted and has no official military designation. Thus the SEALs referred to the experimental weapon as the "China Lake grenade launcher" in reference to the facility which produced it.

	All four remaining original China Lake Model grenade launchers are on display in museums. Serial number 4 is at the National Navy UDT-SEAL Museum in Fort Pierce, Florida while serial number 13 is on display in the War Remnants Museum in Ho Chi Minh City, Vietnam. Serial number 2 is stored at the Naval History and Heritage Command in Washington DC. One additional launcher is on limited display in a military restricted US Navy facility at NSWC Crane.
