- 11-87 Super Mag Barrel Seal Activator
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!

Design[edit]
Ms sql management studio for mac. The Model 11-87 is a gas-operatedsemi-automatic shotgun. Upon firing a shell, some of the high-pressure gases from the burning gunpowder are diverted through two small holes in the underside of the barrel,[2] forcing a piston and the bolt toward the buttstock, which in turn ejects the spent shell. A spring then forces the bolt forward, sending a new shell from the magazine into the chamber. This gas operation has the effect of reducing the recoil felt by the shooter, since the total recoil energy is spread out over a longer period of time than would be the case with fixed-breech shotguns.[2]
The Model 11-87 incorporates a self-compensating gas system design, which allows the gun to operate with a range of loads, from light 23⁄4-inch (7.0 cm) shells to 3-inch (7.6 cm) Magnum shells, without any adjustment by the operator. It is manufactured in 12 gauge and 20 gauge; both will cycle 23⁄4-inch and 3-inch shells.
A lightened version of the Model 11-87, the Model 11-96, was offered in the late 1990s in 12 gauge only.[3]

Operation[edit]
Some Model 11-87 shotguns, especially those with barrels shorter than 26 inches (66 cm), or Magnum models, may have issues cycling light target and birdshot loads consistently.[citation needed]
A 12 gauge model that accepts 31⁄2-inch (8.9 cm) shells is marketed as the Super Magnum.[1] This model comes with an extra component on the magazine tube called a 'barrel seal activator' that helps cycle lighter loads.[1] The barrel seal activator is meant to be removed when using 31⁄2-inch or 3-inch shells, and installed when using shorter shells.[1]
