The weapon is simple to operate and all metal surfaces are treated with a coating for corrosion protection, plus long-life dry film ...
The instructions from several manufacturers state that their suppressors need not be cleaned at all. [citation needed] Furthermore, legal changes in the United States during the 1980s and 1990s made it much more difficult for end-users to legally replace internal silencer parts, and the newer designs reflect this reality.

Gemtech (stylized as GEMTECH) is an American manufacturer of silencers (suppressors) for pistols, rifles, submachine guns, and personal defense weapons (PDWs). The company also produces ammunition and various accessories. [2] [3] [4] Gemtech was founded in 1993 and is headquartered in Eagle, Idaho.
When the transfer is complete, the piston is on the compression stroke but the exhaust port is still open, an unavoidable problem with the two stroke piston port design. To help prevent the piston pushing fresh mixture out the open exhaust port the strong acoustic wave (produced by the combustion) from the expansion chamber is timed to arrive ...
Cylinder and ports, viewed from above. Schnuerle porting [1] [2] is a system to improve efficiency of a valveless two-stroke engine by giving better scavenging.The intake and exhaust ports cut in the cylinder wall are shaped to give a more efficient transfer of intake and exhaust gases.
A stroke is the action of a piston travelling the full length of its cylinder.In a two-stroke engine, one of the two strokes combines primarily the intake stroke and the combustion stroke, while the other stroke primarily combines the compression stroke and the exhaust stroke, though technically since both ports are exposed during both the combustion and compression strokes, some reversion ...
The PBS-1 silencer, designed for use with the AKM to reduce the noise when firing, was introduced in the 1960s, and was used mostly by Spetsnaz forces and the KGB. [3] [4] [5] They were used by the Spetsnaz in the Soviet–Afghan War in the 1980s, requiring the use of the AKM (modernized variant of the AK-47), because the newer AK-74 did not have a silencer available.

[2] The LAPD's Model 15 revolvers (and department issued Model 36 5-shot, 2-inch barrelled snub nose Smith & Wesson revolvers for detectives, plainclothes, undercover and other officers' off duty carry) were modified to be fired double-action only. This was accomplished by the department armorer who ground the full cock notch from the hammers.
