In contrast, one suppressor designed for rifles firing the powerful .50 caliber (BMG) cartridge is 509 mm (20.0 in) long and 76 mm (3.0 in) in diameter. [ 36 ] Two ancillary advantages of the silencer are recoil reduction and flash suppression.

Though this designation is often assumed to be unique, this is not always the case, e.g. there are three different 20×110 mm types which are not compatible.
The Anzio 20/50 has approximately 22,000 ft⋅lbf (30,000 J) of kinetic energy with an 800-grain (52 g) bullet. It does this by taking the .50 BMG projectile, which already is relatively large and travels extremely fast, and increases the already supersonic bullet to over 1.3 times its normal flight velocity, creating more kinetic energy ...

The VSS Vintorez suppressor and operating systems are exactly the same as the AS Val, but optimised to fire the 9×39mm SP-5 subsonic cartridge with a hardened steel or tungsten tip to defeat body armour. [11] The AS Val uses a 20-round detachable box magazine, while the VSS Vintorez uses a 10-round, though they are interchangeable. [4]
