Back pain is also common with increased cell phone use, especially if you hold the phone between your neck and shoulders as you multitask. Long periods of cell phone use cause you to arch your neck and hold your body in a strange posture. This can lead to back pain, says Healthcentral.com.
A recoilless rifle (RCLR) or recoilless gun is a type of lightweight tube artillery that is designed to allow some of the propellant gases to escape out the rear of the weapon at the moment of ignition, creating forward thrust that counteracts some of the weapon's recoil.lder recoilless rifles are still used by the U.S. National Park Service and the U.S. Forest Service as a system for avalanche control. The Washington State Department of Transportation uses a 105 mm recoilless rifle for avalanche control on Interstate 90.
The equipment to alter a semiautomatic weapon and have it fire like an automatic weapon is known as a bump stock. How does it work? A bump stock is a piece of plastic or metal molded to the lower end of a rifle. The device allows a shooter to fire dozens of rounds in seconds by harnessing the gunâs natural recoil. A rifle with this type of mechanism is optimal with a high-capacity magazine that can hold between 60 and 100 rounds and a hand grip that allows a shooter to push the rifle away from the body to bounce, or bump, the weapon into the trigger finger.
