    I have a 30 inch step rib trap that is brand new but I forgot what it fits. I think it's for an 11-87 but I don't remember how to tell for sure. Can anybody tell me how to tell the diffrence? Thanks Jeff

    The 1187 gas cylinder (barrel hanger, barrel ring) are stepped. The diameter at the front is smaller than the rear.

    Most of the time the barrels will interchange, but you may have to use an 1187 fore end with a 1187 barrel and vice-versa.

    I do not beleive they ever made a 30" step rib fixed full trap barrel for an 11-87. Believe they were all choke tubed. Also don't beleive they ever made a step rib barrel for an 11-87 - but I could be wrong on this one. I know they made some in between thing with the rib higher in the middle or some such silliness. If it is fixed choke - it's for an 1100. I do not know if the 11-87 target barrels' gas cyliders are stepped because they are all chambered for 2 3/4 inch shells, which on a regular 11-87 barrel requires the additional metal gas pressure compensating ring in order to cycle. One way to tell for sure - the 1100 gas seal location is further down the barrel (if memory serves) than on the 11-87 - so an 1100 barrel will not fit on an 11-87. It will hang up on the o-ring, just shy of fully coming into the receiver. If you look at the o-ring detents on an 1187 and an 1100 magazine tube, you will see they are not in the same place.

    The extractor slot on an 1187 barrel is wider than the slot on an 1100 barrel. An 1187 extractor won't fit in an 1100 barrel. HMB

    Remington did make an 1187 full choke step rib trap gun.

    Agree with Rick. I have two of them, 30 and 28 inches, both marked "Target". JM

    No step rib on the 11-87 trap barrel? No fixed choke on the 11-87 trap barrel? I think so.

    If it's an older 1100 barrel, the extractor notch will be thinner, and the 11-87 extractor won't fit in it, unless someone has filed the notch out to work. The 11-87 trap barrels aren't compensated, and look just like an 1100 barrel. If the extractor fits, then it is a good swap, and it doesn't matter what it started life as. I have multiple copies of each. Mark

    Well.. That is just as clear as mud!

    I know for a fact that they did make step rib 11-87 barrels.

    I know they made fixed and choke tube models.

    I know that some of them do not say TARGET on the side.

    Newer 1100 barrels have the larger slot as well so that is not a way to tell for sure either.

    Still looking for a certain way to tell the diffrence.

    Guys I do not have an 11-87 gun. I have all 1100 actions so using the 11-87 action to help in some way is not an option.

    Are you wanting to use it or sell it? If you have 1100 guns, it will work fine. Just put it on and go shoot it. If you are trying to sell it and are worried that it might have a slimmer extractor slot, take an older 1100 bolt out of an action and see if there is a gap when the extractor fits in the notch. No gap, 1100 barrel. Mark

    Jeff measure from the back of the reciever tang to the front of the ring that goes over the mag tube ,then measure a known 1100 barrel if they are the same its 1100 I think LOL.Early 1187 barrels had a seperate gas ring under the stamped steel forend stabilizer that can be welded to stay on. the placement of the o ring groove is just a little different on the mag tube between the two. The 1187 will work on the 1100 but not the other way.Sorry Im not home to check, others chime in. Jeff

    You had it right but being a simple minded fool I needed 870 shooters picture to help my short bus riding self to understand. You had it right from the get go. I just didn't understand, even though I can see now your post was designed to help the challanged. Thanks for your post and 870 shooters picture. As soon as I saw the picture I knew the diffrence.

    If I had an 11-87 barrel, I am pretty sure I would have remembered that smaller portion at the front being the most obvious diffrence but the barrels are all 1100's around here any more.

    That is the proof I was looking for. The barrel I have is a new near 1100 step rib trap. Now if I can find my bore mic.... Jeff

    Damn! Either I can't write or yall can't read.

    1187 barrels, all 1187 barrels have stepped gas cylinders. Step rib, flat rib, slug, backbored, standard bored, Remchoked, not Remchoked, 2 3/4" Target, 3", 3 1/2" Supermag.....

    All 1100 barrels do not have stepped gas cylinders.

    That's it no more.

    Mike was typing his post while I was editing my second post. He had it right the first time. I was just not getting it and needed the picture. Thanks for correct answer the first time!

    If I had undestood your clear and concise answer it would have been easy.. but I needed the picture because I was educated in the public school system. Jeff
