Installing Polychoke on Remington 1100 12 ga 30" Full Choke Barrel?

[jkpq45]

Hello All,

I have a 30" fixed full choke barrel on my 12 ga rem 1100--I'd like to shorten it a bit to open up to cylinder bore, then install a polychoke as I've used them on other firearms to great success. The question is--which parts do I need?

Numrich lists several parts--"collet," "adjusting sleeve," etc. Which do I need to solder onto the cut-down and turned-down barrel, and which screws onto that threaded sleeve?

Advice is appreciated. Links to parts available from numrich provided below.

Thanks,
jkpq45

I'm not sure how much barrel you would need to remove to eliminate the full choke portion of the barrel. In the fixed choke bbls I've looked down it appears to tighten up incrementally in 4 to 6'' stages. Not just at the tip like a screw in choke. You need to find a way to measure the ID of your bbl in order to know how much to remove or your polly choke may not perform as expected.
More experienced folks will surely chime in to either correct me or give you more sound advice.
I would be more likely to buy a bbl that is threaded for screw in chokes and just screw in a Poly choke. For some reason soldering a choke on a barrel just gives me the heebie jeebies.

Roger that--understand the trepidation. Can't afford the $200+ for a new 1100 barrel, I figure I'll try to booger this one up first and, if necessary, buy a new/used on the way I want it (ie already threaded and with a vent rib.)

Just had another thought I saw that Mossberg is making replacement barrels for some Remington shotguns and at a greatly reduced price so if you need one check into this could save you some cash.

Send the barrel to Carlson's and have it cut and threaded for choke tubes.

I believe it would be a much more satisfactory result then a cobbled up used Poly-Choke from Numeric.

The Collet is the part that is soldered onto the barrel. The adjusting ring is the part that you screw by hand to adjust the collet fingers to the desired restriction.

Installing one yourself is a whole other matter. Unless you are an accomplished machinist, good luck on getting it to pattern in the same zipcode.

I'm not a gunsmith, but, as said, getting everything aligned correctly is critical to getting the gun to shoot straight. Unless you know what you're doing or are willing to risk ruining the barrel, this sounds like a job for a professional.

If you want a PolyChoke just send the barrel to them and they will install a new one for you! www.poly-choke.com About $155

Ahh, fellows. This ^^^^^^is what you want to do. It will be sooooo much nicer.

Quickest way to devalue a gun known to man. If you must have a Poly, get the barrel threaded and then you can use a Poly II and remove it.

Gotta go with the majority here. Send it to Briley or Orlen and have it set up for tubes.

I've run across a few Polys installed by shade tree mechanics that didn't shoot to the right Zip Code.
