The saboted light armor penetrator (SLAP) family of

armor-piercing ammunition. In the US it was developed by the Marine Corps during the mid/late 1980s and was approved for service use in 1990 during Operation Desert Storm. It uses a reduced caliber, heavy metal (tungsten) .30 inch diameter penetrator wrapped in a plastic sabot
of .50 inch diameter, and the .308 SLAP round was a .223 inch diameter penetrator core within the .308 inch plastic sabot.

Design and use

The SLAP design incorporates a polymer sabot, which allows for the use of a tungsten penetrator projectile of a lesser diameter than the original bore. By using the casing of a large cartridge with a lightweight projectile, the velocity of the projectile is greatly increased and the sectional density is improved without requiring a (potentially dangerous) increase in chamber pressure.

SLAP rounds have been designed for use against lightly

armored vehicles and aircraft
.

Saboted ammunition should not be used in firearms with muzzle brakes unless the muzzle brake has been specifically designed for such use.[1] 50 SLAP ammunition is completely interoperable with M2 machine guns with stellite liner.

Types of SLAP ammunition

The term "SLAP" technically only applies to the U.S. version. This article presents a genericized view when showing ammunition of similar design and purpose of other nations.
List of SLAP ammunition
Caliber Country Designation Description
7.62×51mm NATO  United States M948 (standard)
M959 (tracer) 		Abandoned. Intended for the M60 machine gun, but caused catastrophic barrel failures when tested. Penetration was increased, but not to same extent as in the .50 BMG SLAP round.[2]
7.62×51mm NATO  Sweden 7,62 mm Sk Ptr 10 PRICK In use with the
Psg 90
sniper rifle.
.50 BMG (12.7×99mm NATO)  United States M903 (standard)
M962 (tracer) 		For use in
M2 machine guns only (the open-tipped round design reduces compatibility). The 355 grains (23.0 g) projectile runs at 4,000 feet per second (1,200 m/s), for a kinetic energy of 12,200 foot-pounds force (16,500 J).[3]
14.5×114mm  China DGJ-02 SLAP Mainly intended for QJG-02. Dual-color tracer.

Production

U.S. SLAP ammunition is produced by the

Olin Manufacturing
. The team began production of the ammunition in 1985. The sabot that contains the sub-caliber is manufactured by Cytec Industries.
