    I have a guy telling me That I can take my Rem 870 20 ga. and swap out the barrel with a 12 ga. and it will function fine. I am not to up to date on my shotgun info so I just wanted to see if someone can tell me if this is true or not.

    I believe so, the owners manual should say something about barrel interchangability. I read all model 870 12 ga. barrels are interchangable, except the super magnum.

    NO you cannot swap out a 20 ga barrel with a 12 ga barrel!!!!!!!!! You CAN however swap out with other barrels of the same gauge.

    Do not attempt this!!
    20 ga. & 12 ga. are different diameters.

    I really dont understand how this will work, or why anyone would want to do it for that matter.

    Where (on what pg.) does it say that and what exactly does it say? Remington has all their Owner's Manuals on-line and I'd like to see this.

    Ok I just read the online owners manual and it says all barrels same gauge are inter changeable mine must be a misprint or something cause it says some gauges are interchangeable. its on page 17

    even if you could put a 12gauge barrel on the 20gauge receiver...i doubt you could load 12gauge shells into the magazine tube??

    I own a 870 Super Mag in 12gauge..I can swap barrels that are the same gauge..I can swap a 12g 2 3/4 or 3in barrel, but you can't swap a 3 1/2 barrel on a 870 made for 2 3/4 and 3 in..I can put on a fully rifled slug barrel made for 3in on my gun. I looked on the Remington Web site for the info. If you have the Super Mag you can swap down to the other barrels but you can't swap up...Make sense ?? If you have any questions goto the Rem web site and look up shotguns and there is a section on Barrel swaps.

    If you have a 12 gauge and you want to shoot 20 gauge shells you can buy the adapters that fit in the barrel that will allow you to shoot 20g shells in a 12g..or 16..28..or even 410 shells. I have seen these avertised in magazines...Shotgun News...I don't know how well they will patteren but I know you can buy them. I hope this helps...

    im not questioning your statement, but that doesnt make sense on swapping up? I thought a 3 1/2 inch means the size of the chamber, when a shell has been shot and expanded, what does that have to do with the barrell? Me and my brother both have 870s mine is the express his is the super and both of our barrels are the same, it says 3 1/2 for super mag reciever only.

    anyone have any input on this?

    Your barrel's chamber measures 3" and your brother's barrel's chamber measures 3 1/2". That's the length of the shell after firing. Not only is the receiver longer on your brother's super, but it also has the longer chamber. You cannot put a 3 1/2" barrel on a 3" gun and expect to shoot 3 1/2" shells.

    yea I know I wont be able to shoot 3 1/2" shells, but his gun is a few years older than mine and his barrel has had several thousand shells through it, and i do believe the more shells through a shotgun the better it shoots. I was just going to swap out barrels for turkey shoots just because his barrel has been broken in.

    I dont NEED to do that I know, but im just curious. I really dont have the time to break mine in quite like his is, and when I do have range time, I try to practice with a rifle, because thats what I use in the field a lot more than I use my shotgun.

    I havn't noticed shotgun barrels to pattern better after several thousand rounds-to me it seems they pretty much pattern the same. Does your brother's gun have a different choke tube? If so that would account for the different pattern.
