Adding a Choke to a Shotgun

[Amazingkg3]

Hey guys,

I just picked up a project 870. Still debating whether I am going to go with a Vang comp porting option or use chokes in it. But I have a quick question.

My Remington appears to be just a straight cylinder. I am framiliar with the different kind of chokes (cylinder, modified, full, etc) and what they do to affect spread pattern. That said I am not really framiliar with how Chokes are installed. I imagine the barrel is threaded internally and you just screw them in, but my barrel does not appear to be able to do that. Do I need to have a gun smith mill in threading, or buy a new barrel?

I also see there are some chokes that mount onto the front sight post and secured on, but I don't have much faith in that.

If a shotgun guru could show me the path, I would appreciate it.

The type of choke should be stamped on the barrel, but you may have a barrel that has been cut down, in which case it could be a true cylinder.
You could use calipers to check the diameter, standard Rem. bore is 0.727" +/- .002".
Screw-in chokes can often be added but last year I checked around and did not find anyone that could do it in Calgary. One guy said he had the tools but had never done it.
You may be able to find a Remchoke barrel in the EE parts and bits section.

Elwood looks like they can do it for 100, but at that price I guess I should get the rem choke. Do they come in lengths in the 18 and under? It's not for hunting or sporting use.

if It's not for hunting or sporting use, (security\defense) seriously I dont think you need a choke.... cylinder or improved with buckshot it is the best setup...

At $100.00 for the first choke tube and threading I would buy another barrel.
It is cheap insurance that it will work and have the options of installing a choice from full to improved cyl. should I wish to.
Call Epps and ask what they have available to suit your needs.
And imo stay away from that 12 inch barrel that is avilable cause really if your life depends upon it are you really going to shoot from the hip?

As far as I know, the shortest 870 barrel available with Rem Chokes is the smoothbore 20" Wingmaster Deer barrel with rifle sights. The Remington part number is 24545. I paid about $250 for one of these barrels from Wholesale Sports about a year and a half ago. If you want choke in a shorter barrel, it would have to be either threaded for choke tubes or Vang Comped (with or without ports).

What does having a 12" barrel have to do with shooting from the hip?

Agreed, while they look impressive and short, I really feel at place with an 18 inch barrel. I somewhat see 12" as Breaching tool/Immediate close threat, 14" as Municipal and urban shoutgun, and 18" rural and urban use. At least in terms of using a shotgun in regards to policing, security, etc.

Thanks for the help guys.
