Gunsmith Question--adding removeable chokes to shotgun barrel

[AAShooter]

Thinking about having my 30" full-choked, vented-rib barrel from my 12 gauge 870 modified the accept Browning Invector Plus chokes.

Anyone know if that can be done easily/cheaply. Any recommendations as far as gunsmiths that would do a nice job of it?

I would recommend Carlson's Chokes or Briley. Carlson would be cheaper and just as good in my opinion.

First off: is your barrel permanently fixed with a choke or do you have a screw-in choke? If it's the former, I'd suggest getting a new barrel, unchoked, and either get it threaded at the manufacturer or take it to a gunsmith and have them thread it. If it's the latter, find out the thread pattern on your screw-in choke and see if it's the same pattern on the choke you're looking at. If it's not, see if you can get an adapter, and if not, new barrel.

Short version: rethreading or drilling out and rethreading a barrel is not something you want to do.

The current barrel is one I used to use for duck hunting back in lead shot days so it is a fixed choke. I have lots of Briley Invector Plus chokes so I was thinking of just having it modified to use the chokes I already have.

I might just be better off buying a new Remington 870 barrel with removable chokes and just use Remington chokes.

It would probably be cheaper

Looks like a new barrel with removable chokes will run $250+

Look for a barrel just threaded for chokes. Most after-market chokes are designed to work with manufacturer threading for a reason.

First of all do you know what the bore on the 870 is ??? Not all 12ga chokes would work for all 12ga barrels. 12ga barrels start at .729 and most of all the target guns are at .736-.750. If I am not mistaken the Invector Plus have bore diameter of .742, and your older Remington should have a bore diameter of .729.

I would recommand you selling your existing barrel and buying one with the RemChoke system in place. That would be you least expensive route. The Carlson and Briley are great chokes but I would leave them for more expensive guns where barrels arn't as inexpensive to replace.

I have the Briley thinwalls in a Browning 12 Gr5 in 28ga and a Browning A5 DU 50th Ann. So I like the Briley product, just in your case I won't recommand them.

It is sounding like getting a new barrel with the Rem choke is the way to go . . . like I need yet another set of chokes to keep track of. Thanks for the suggestions.

Thanks, I will take a look. As far as the chokes, I need all I have.

AAShooter, if you never tried the Briley extended long chokes, go for it and spoil yourself, you'll laugh at how crappy factory tubes really are after that. While they have it, have them lengthen the forcing cone too. You won't believe the difference in the patterns.

i had this done with one of my 1100 barrels. and even though it was modified fixed. once you insert another sleeve into the fix full you have it will get even smaller(more constricted)

it worked good for going tigher as i made a nice tight trap barrel out of it but the opposite direction will be self defeating.

ie: your fixed full is .690 and you drill it and put in an ic that will fit inside.

you now have a .690 barrel drilled and sleeved to .670 even though your choke says ic. diameters are what they are reagardless of what you call them

you are better off buying a used(if you can find one) or aftermarket barrel with chokes.

hattles is right on with his prices but having 2 barrels is a better deal than one.

I had it done many, many years ago. Had a 30 inch 870 barrel shortened to 24 inches and threaded for choke tubes. It worked well, but it cost me about $200 when all was said and done.

With as many barrels as there are out there now, I'd think that purchasing a separate barrel set up already for tubes would be an easier and cheaper way to go.
