The Rem Choke tube system is used on a number of Remington shotguns including the Model 870, Model 1100, and Model 11-87.

Rem Choke Tube System

This is a choke tube developed by Remington which is designed for a number of their weapons. In order for a Remington shotgun to be compatible with a Rem choke tube system, the muzzle end of the barrel has to be threaded for an interchangeable screw. That is how the choke tube will be able to firmly connect to the barrel and sustain the impact of gunfire.

There are certain Remington firearms that already come with a Rem choke tube system. Look for them in the Model 887, Model 1100, Model 11-87SM, Model 11-87, Model 870SM, and Model 870.

Remember that if you don’t use the choke tube in the barrel of your weapon then it could damage the threads after you shoot it. Once that happens, you won’t be able to attach the choke tube to the barrel. The only way to rectify this situation is to replace the entire barrel. Therefore, be sure to use a Rem choke tube with a Rem choke barrel in order to sustain the life of both parts.

There are many types of Rem chokes you can use in your Remington weapons; full choke, modified choke, improved cylinder choke and many others. The full choke will give you the tightest constriction inside the bore. The modified choke will provide a lighter amount of constriction and the improved cylinder choke will be even lighter than that. If you want to eliminate all constriction, then you would just use a cylinder bore. But chances are that’s not what you want to do. A constricted bore helps with long range shooting and accuracy, which is why the Rem choke tube system is so popular for Remington shotgun owners.

If you want to purchase the choke tubes separately then expect to pay anywhere between $20 and $50. But if you want to pay for the installation of the choke tube system for your barrel then it will cost at least $99. People who are new to gun upgrades should consider paying a professional to install the choke tube system if it doesn’t already come with it.
