I bought a new 11-87 sportsman this year (super-mag) after shooting an 870 forever. The 11-87 cycles flawlessly no matter what I shoot through it. No problems there. The question is regarding the piston/seal assembly. The counter-clerk showed me how to put the assembly together, but my manual seems to disagree. To make it worse, the Remington website seems to show parts I don't even have in my gun (not the barrel actuator...I know I don't need that). the website site shows a separate 'piston'. All I have is a single metal-ring assembly and the infamous rubber o-ring. I don't have a 'piston' thingy. Can anyone tell me the correct placement of these parts on my magazine tube in laymans terms? Am I missing a part? Is this a 3-part assembly or 2 part assembly? It sounds weird but my part looks nothing like the one in the manual. I would also like the correct orientation of my metal ring assembly since I don't trust a thing the clerk did now. I realize he probably positioned the o-ring wrong now Funny thing, the dang gun still worked great. Ideas? |

Jan 07, 2013 On to my issue: The 11-87 Super Mag is similar to the 1100 in that they use a piston asssembly and o-ring in the gas system. The Super Mag also uses a Barrel Seal Activator in between the o-ring and the piston that allows it to cycle 2-3/4' loads. Upon disassembly for cleaning and relubing, I noticed that the activator was missing. Mar 26, 2008 The manual suggests removing the barrel seal activator when shooting 3' or 3 1/2' shells. I read a comment on another forum indicating they put the barrel seal activator back in when shooting the 3 1/2' and it worked fine? Unfortunately, I didn't have it with me to try. I have also read problems with the o-ring. Remington BARREL SEAL ACTIVATOR SUPERMAG REMINGTON 11-87 Misc Gun Parts.
I recently purchased a Remington 11-87 Sportsman Super Magnum. It is used, but in very good condition. I tried to shoot some 2-3/4″ shells through it and they didn’t cycle correctly, but, after looking through the manual and removing the forearm I don’t think it has the “barrel seal activator” that is required for it to operate correctly with the lower pressure shells. No problem- bought it used, previous owner took it off to shoot 3″-3-1/2″ shells. Figured I would order a new one and, might as well get new barrel seal and other parts while I’m at it.
The problem is, I got the new parts and just took the shotgun apart and now I think the parts that were there were installed incorrectly, and, the schematics that I can find have “drawings” that show parts that, honestly, don’t look like that parts I have. I also found that it doesn’t even have the O-ring barrel seal at all… I don’t know how it was even shooting, but it should work GREAT when I’m done….
So, what I was hoping, is that someone could post pic of the correct assembly order, as well as position of the piston/piston seal assembly, barrel seal activator and barrel seal. Going by the images in the manual schematics I can’t tell which way is “up”…
😕
Thanks!
I have the same gun and have the manual somehwere around as I bought it new but it has never cycled correctly unless I shoot real heavy loads. I use it for a deer gun and I have to shoot the 1 3/8 oz brennekke black magic magnum to get it to cycle. Remington and Winchester 3 in rifled slugs don’t always cycle. Frustrating…. 😡
2 3/4″ shells don’t work at all. The 1 3/8 oz I refer to are 3″ obviously
Go to brownells.com scroll down to the bottom of the page and click on schematics then click on rem, scroll down abit then click shotguns, you should see 11-87 supermag. Hope that helps.
Gentlemen:
Something is amiss with your guns. Have you either cleaned the gas ports or inspected the o rings? The gas ports are located at the barrel ring that attaches to the barrel, they are angle bored into the barrel. A pipe cleaner will usually do the trick. I’m guessing but if you would take your guns to a competent gunsmith and simply dissembled them in front of them they would point out something fairly quickly.
IMO if your having problems cycling lighter loads your ports are not letting enough gas to the piston or the seal on the piston (O ring) has been damaged.
Gas operated systems are subject to friction free operation in the gas chamber. All of these type guns will cycle rough if dirty.Good luck!
