Hi I took and 870 Barrel and had gas ports drilled into barrel and it works.. I'm not sure that Remington would approve but you might check it out with a gunsmith and get his opinion. Again I did it but that doesn't make it right so I recommend you run it by a gunsmith and see if see a problem.. I did with a slug barrel 20 years ago and have not had any problem.
You will need a good gunsmith. The information you seek is not readily available in published material.
Frame sizes are different, you will need a gunsmith and money to do this.
You need to cycle the action for every ejection.
Depending on what the choke constriction is, it will only get so tight. Have a gunsmith lengthen the forcing cone and polish the bore. If you need it tighter, you will have to consider backboring the barrel, or having screw-in chokes installed. sales@countrygunsmith.net
You need to look up the barrel codes, the details are on the Remington Society of America here: http://remingtonsociety.com/rsa/questions/barrelcodes
Need to check the barrel date code. Remington Society of America, Manufacture date link has all the details.
Disassemble to do what? To remove the trigger group you need to push out the two pins in the receiver to remove the trigger group. To remove the bolt you need to take the barrel off which requires an armorers barrel wrench.
They were made from 1948-1970, you need to look up the date code stamped on the barrel. Check the manufactured date link on the Remington Society of America.
Remington Firearms are dated from a 2 or 3 LETTER code stamped on the barrel, left side about a quarter inch from the frame. If that is the original barrel, the Remington Collector's Association website has the key to checking month and year of manufacture. You may need a good light and a magnifying glass to see the letters.

With Remington rifles and shotguns, age is not determined by serial number. It is determined by a 2 or 3 letter barrel code. Small letters, on the LEFT side of the barrel, just in front of the receiver. You may need a strong light/ magnifier. Once you find them, Google search for BLACKPOWDERX Remington. That should take you to the Remington Collectors Website, with the barrel code date tables. BLACKPOWDERX was the code used by Remington- B=1, L=2, A=3, etc.
You cannot tell by the s/n. You need the barrel code, located on barrel, left side, at the frame. Find that number, post it and I'll see if I can help.
