870 extension bracket ?

[moorerwc]

I finally located a Remington factory blued mag. extension for my blued 870P, but I have had problems installing the bracket. It seems that the crimp in the middle of the bracket is too wide to allow it to be installed. When I pushed it on and got it nearly into place, it caused the extension tube to cant down.

Has anyone had similar problems? Or am I just missing out on some secret of installing this part? I would appreciate any suggestions before I start calling my dealer and remington on Monday.

Thanks,
Chad

Turn it upside down and try again.

Dave, are you suggesting that I use the sling stud as the bead sight? Could you clarify your suggestion a little?


Thanks,

[870]

Are you placing the screw through the crimp in the mag tube?

870.

 

[moorerwc]

870--yes.

Am I the only idiot having trouble with these things?

I have several of these factory clamp/mag tubes and none of them behave the way you've described. Is this a newer 870?
You are certain that you have a factory clamp?

IIRC, the Factory Extensions have a creased area a little down from the muzzle where you put the screw through. There is also a step down near the front of the tube. The nut is separate from the extension tube as well. If you install it right, there should be no trouble. Of course, it only works on the factory tube. You might have a Remington bracket and non-factory tube. Don't know.

monkeyed with it some more today

To answer ya'll's questions about it being factory or not--everything came in a marked remington factory box and was advertised as remington factory.

The bracket seemed to go on easier today and, yes, I am putting the screw along the dimple in the tube. But the open end of the bracket doesn't fit properly around the bbl.--the sides flare around the barrel slightly and the tube seems to be pushed at an angle when the bracket is present--it lines up straight without the bracket. Also, when trying to check for function with dummy rounds only five fit into mag. with the bracket in place, but with the bracket removed the tube straightens up and holds and feeds all 6 rds. properly.

The Remington tube is strong, try running it without the bracket. That or you can get the brackets made for a Tac-Star extension. I've never heard of the Remington bracket doing that.

Can you post us a picture?

Got online help from Remington

Remington's online service is very good. They said that recently they have slightly shortened the barrel guide ring on their 870 line but did not want to be directly quoted or give too many details online b/c they prefer to handle each customer/gun on a one on one basis. I had received the old style bracket with my kit and they are sending me the new style bracket.

This is very disturbing and not the first time I've heard this nasty rumor.
If this is true, and I've no reason to doubt you, then new production barrels should also not fit older guns and old barrels will not......
What ever could they be thinking? Have they actually taken a proactive stance towards stopping folks from buying and retrofitting older, better-built guns?
Why would they suddenly feel the need to redesign a perfect gun?
Could I be more suspicious or paranoid?
Mike

PS. I am sure that there is some financial/manufacturing reason like the "they're not PC!" dimples.........

[moorerwc]

whoa

I don't have enough info to back up what y'all are saying. I don't _think_ that there would be enough of change to cause a problem when using a barrel with the standard mag. tube. I did tend to stack the tolerances when I added the extension tube and then a bracket that was too long.

I'd assume it was shortened when they changed over to the plastic magazine spring retainer instead of the metal one and detent in the barrel?

That is unlikely. I have a few of each and the factory mag tube extensions and brackets that I use are interchangeable. This is much more recent.

does the extension run straight without the bracket?try this...take the barrel off the gun- slide on the extension and bracket and tighten them down on the barrel,now set the barrel into the receiver and the seperate bracket that holds the mag extension to the mag tube and see if they line up....ive heard of the slight cant but usually they were on express models with the fact mag extensions.the choate mag extensions are steel and work jus as good if the fact doesnt.choate comes with the spring and a orange follower and spring guide along with their own clamp.

factory kits should have the spring,the mag ext tube,mag clamp and a seperate threaded coupler that holds the shotguns mag tube to the extension(a threaded ring that pulls the whole deal together)sounds like a bad clamp if everything else fits.

 

[moorerwc]

The extension without clamp is straight and true.

Today the new clamp from Remington arrived. I compared it to the original clamp and just by eyeball it looks like the crimp in the center of the clamp is about a 1/8" shorter on the new one. The new clamp is also marked with a large "X" near the screw. It fit right onto the gun and extension without any problem.

I am now happy and hope that this thread will help anyone else out there that has/is having problems.

Where did you get your tube? I looking for a Remington factory blued magazine extension tube for my 18" barrel 870. Hank

 

[moorerwc]

I got mine factory tube from a guy who was advertising in shotgun news. I can't remember his name--just try looking through that publication.
