The MP5SD ("SD" meaning Schalldämpfer, German for "sound suppressor") is a variant of the MP5 with an integral suppressor, introduced in 1974. [34] The integral suppressor, built around its 5.7-inch barrel, uses a unique two-stage design that allows it to operate silently in most environments, including when wet, while still remaining reliable ...
A silencer, also known as a sound suppressor, suppressor, or sound moderator, is a muzzle device that suppresses the blast created when a gun (firearm or airgun) is discharged, thereby reducing the acoustic intensity of the muzzle report (sound of a gunshot) and jump, by modulating the speed and pressure of the propellant gas released from the ...
The heavy, cold hammer-forged barrel is screwed into the receiver and is equipped with a slotted "bird cage" type flash suppressor that is also used to launch rifle grenades (using standard, live ammunition) or attach a knife bayonet (the bayonet is supported by a lug located at the base of the gas block). The rifled barrel has 6 right-hand ...
The UMP was designed in the 1990s by Heckler & Koch (HK), as a cheaper, lighter alternative to the MP5, [5] which made heavy use of polymers. [6] The UMP first entered production in 2000. [ 2 ] It was designed primarily for use by American military and law enforcement units, [ 7 ] as the MP5 was not available in .45 ACP, a round which was ...

The suppressor grid is usually operated at or near the potential of the cathode and prevents secondary emission electrons from the plate from reaching the screen grid. [ 4 ] [ 5 ] The addition of the suppressor grid permits much greater output signal amplitude to be obtained from the plate of the pentode in amplifier operation than from the ...
The UCP was designed to accept an extended, threaded barrel capable of accepting the attachment of a sound suppressor made by Brügger & Thomet. [ 57 ] The design remained in the prototype phase as of 2006 [update] , and had been reported as entering limited trials with the Bundeswehr.
