DO NOT SHOOT THROUGH A MUZZLE BREAK
The M903 .50 Caliber SLAP (Saboted Light Armor Penetrator) was a specialized .50 BMG round developed by the USMC in the 1980s and was loaded in Browning M2 machine guns during Operation Desert Storm. SLAP ammunition can multiply armor penetration by a factor of at least two at any given range, as well as flatten its trajectory to extend its range. Although these have been stored well and are safe to fire (without a muzzle break on), they are more appealing to cartridge collectors due to the rarity of this particular cartridge.
50 BMG SLAP round. For use in M2 machine guns only and Barrett has a specific barrel(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).
