870s - Express barrels on Wingmasters?

3" shells may hang up on the ejection port if you shoot them out of a 3" barrel on a gun that was originally 2-3/4". The fix for this is to replace the ejector with a new style 3" one.
 
It will be shooting only 2 3/4 shells, so im not concerned about chamber size. However, I was told their is an issue with the magazine cap lock system which causes Express Barrels to become unsafe. I looked at my Wingmaster barrels and noticed the magazie ring is slightly different then the Express barrel I just bought, so I was wondering of their is any truth to the rumour.

The newer Express barrels attach differently. It won't have the ball detent the Wingmaster barrel has to lock the mag cap on.
As long as the little hole is there, you can have a ball detent installed.
 
How big an issue is this? Its for my wifes Wingmaster, it will probaly will be used 2-3 times a fall for ducks, with maybe half a box of shells per trip. If we keep an eye on the mag cap, would that be OK?

How much are the mag balls to be installed? Am I better off just selling the barrel and buying a new one?

If the little hole is there, it's a very small job. Yes, you can also just screw it on and keep torquing it tight. As long as you don't forget, it'll work fine.
 
I have both and have switched back and forth, using the screw in chokes from the Express (the barrel that is) on the sharper trigger (receiver) of the wingmaster. You are right about mag nut, if the detent isn't there is may back off the barrels gets lose. The express locks with green plastic cap in the tube and the wingmaster uses the ball detent. I didn't see a way to change them and have them work correctly without a painful/pricey mod. I used to shot trap like this. Torque the crap out of the nut (rubber coated) channel locks. Then wiggle the nut and barrel after about five shots (or every time you reload for duck)
Or Drop the money on another barrel.
Good luck
 
I've got an old 60's vintage wingmaster receiver that is going to be my duck gun this season. It has an express barrel on it that I polished with steel wool and blued. The receiver was modified with a 3" ejector. I've added synthetic stocks, a tru glo extreme glo dot sight and an uncle mikes swivel magazine cap. I just got it back from the gun smith and I test fired 10 3" 000 bucks and half a box of 3" #4 through it with no issues. It isn't pretty, but neither is a tank.

A rather easy fix for your express barrel is to have a hole drilled and a detent installed in the barrel ring to accommodate the Wingmaster mag cap detent system.

A competent gunsmith can do a good job of this inexpensively.
 
Blue Loctite (not red!) can also be used to keep the magazine cap from coming loose with an Express barrel lacking the ball detent.
 
Another solution would be to add a flat Wilson sling swivel under the mag cap. One with the ball detent embedded in the swivel.

That wont work, the Express Barrel DOES NOT have the ball detent. Where that will work is on my Wingmaster, lol. Ive been usng it for years and never knew their was a difference in barrels. Just checked, ive been using a flat cap with ball barrels.

Would a buying a flat mag cap for an Express to use with the barrel be OK?

No, no, it doesn't matter that the barrel doesn't have a detent. The detent is on the swivel. When the swivel is flat against the barrel ring, the detent will protrude forward from the sling swivel for the cap to take hold of. You do have to have a mag cap with the divots on the edge of it. Meaning the earlier style mag cap.

OK, thanks.

Any idea where to get these Wilson flat sling swivels? Google'ing them is an adventure.
 
I've never like the "improvments" Remington did to save money on the Express line. Adding a ball detent to your barrel is worth it IMHO.

Not to mention those two divots in the mag tube...
 
I don't think the ball detent in the sling plate will function with an Express barrel. On a normal barrel, the ball bears against the spring loaded one in the barrel lug, allowing it to function. With no ball detent in the barrel lug, there is nothing to spring load the sling plate ball to allow it to function as a detent.

Has anyone actually tried this?

As opposed to looking at pictures from your commando chair ...


When the sling plate sits up against a flat surface, the detent protrudes as much as it would if the detent was installed in a barrel lug. (The surface in my photo isn't exactly flat, but you can see the detent still protrudes up quite a bit).
Of course you will not have a spring effect as you would with a spring and detent installed, but the mag cap will stay in place indefinitely.

If your barrel lug already has a hole drilled in it, but no spring and detent installed, flop the sling plate so that the detent in the sling plate bears against a flat surface on the other side and does not fall into the hole.

If your barrel lug does have a hole drilled, but no spring and detent installed, (I've seen both on late Express models), find yourself a spring that fits the hole, but being just a bit longer to take up the space of the nonexistent detent in the lug and orient your sling plate so the detent sits atop the spring.

With this idea, you've accomplished the exact same effect as having a detent installed in your barrel lug.

... old guys know stuff! ;)
