gas tube उदाहरण वाक्य

In line with the AK-74M assault rifle variant the RPK-74M lower hand guard, gas tube cover, pistol grip, and new synthetic stock are made from a black, glass-filled polyamide.
In this way when the firearm fires at least some of the combustion gases from inside the gas tube are vented into the handguard area rather than the receiver.
When the rifle is fired, gas is tapped from the gas port to enter the gas tube, driving the bolt carrier to the rear and the counter-recoil upper rail forward.
The origins of the HK416 began with the realization of the deficiencies of the direct gas impingement ( gas tube ) operating system found on conventional M4 / M16-style weapons.
Simultaneously, a quantity of powder gases driving the bullet through the barrel is tapped and acts upon the piston in the gas tube located below and parallel to the barrel.

As the "'CIS 50MG "'is a gas-operated, air-cooled, belt-fed weapon, the gun is operated using dual gas pistons, located in two gas tubes placed on either side of the barrel.

In sophisticated versions of these devices ( called gas tube arresters ), a small spark gap breaks down during an abnormal voltage surge, safely shunting the surge to ground and thereby protecting the equipment.
