A choke is designed to alter or shape the distribution of the shot as it leaves the firearm. For shooting most game birds and clay pigeons, a desirable pattern is one that is as large as possible while being dense enough to ensure multiple hits on the target, at a particular range. The choke should be tailored to the range and size of the targets.
The Beretta 1301 is a gas-operated semi-automatic shotgun produced by Beretta, and imported by Beretta USA in the United States. [1] The firearm has two distinct models: The 1301 Tactical is intended for tactical self-defense and law enforcement applications whereas the 1301 Competition is designed for practical shooting sports such as Multigun or IPSC Shotgun.

Most choke valves in engines are butterfly valves mounted upstream of the carburetor jet to produce a higher partial vacuum, which increases the fuel draw. [ 1 ] In heavy industrial or fluid engineering contexts, including oil and gas production, a choke valve or choke is a particular design of valve with a solid cylinder placed inside another ...
The Beretta U22 Neos is a .22 Long Rifle semi-automatic, single-action pistol using a slide blow-back system, that has been manufactured in the United States since 2002 by Beretta USA. [2] The pistol will accept interchangeable 4.5, 6 or 7.5 in (110, 150 or 190 mm) barrels in blued or stainless steel finishes.
The Xtrema2 was released in mid-2004, to answer the call from hunters and target shooters for a complete do-all shotgun. Beretta's goal was to produce a shotgun that could reliably fire 2¾” loaded with light target loads all the way through the 3½” super magnum round without any modification or settings to be dealt with.
A blowout preventer (BOP) (pronounced B-O-P) [1] is a specialized valve or similar mechanical device, used to seal, control and monitor oil and gas wells to prevent blowouts, the uncontrolled release of crude oil or natural gas from a well. They are usually installed in stacks of other valves.
In oil and gas production a choke manifold is used to lower the pressure from the well head. It consist of a set of high pressure valves and at least two chokes. These chokes can be fixed or adjustable or a mix of both. The redundancy is needed so that if one choke has to be taken out of service, the flow can be directed through another one.
