Carlson’s Choke Tubes 15523 Sporting Clay Mobil 20 Gauge Improved Cylinder Stainless Steel

Description

Carlsons Choke Tubes Cylinder choke tube in 20 Gauge.

A choke is a short constriction at the muzzle end of a shotgun barrel. Narrowing the bore by a few thousandths of an inch slows how quickly the shot column opens, so the same gun and the same shell can throw a tight pattern or a wide one depending on which tube is fitted.

Cylinder is no constriction at all – the bore runs straight out. The shot column opens fastest, which suits the shortest ranges and slugs.

This tube is cut for the Beretta/Benelli Mobil thread system. Choke threads are not standard across makers – Invector, Invector-Plus, Beretta/Benelli Mobil, Optima, Rem Choke and Accu-Choke are all different – so the system has to match what is cut into your barrel. It is the commonest way people buy a choke that will not fit.

Gauge has to match too: this is 20 Gauge, and a tube of another gauge will not thread in.

A note on steel shot: steel does not compress the way lead does, and driving it through a very tight constriction can damage a barrel that is not rated for it. Check the maker's guidance for the tube and the barrel before shooting steel through a tight choke.

Patterns vary between guns, loads and shot sizes. The only way to know what a given choke does with the ammunition you shoot is to pattern it on paper at the distance you intend to use it.

Chokes are parts, not firearms, and ship directly to your address.
