Looking for Remington 870 parts because I'm incompetent...

Just curious if anybody knows where I can get a spare remington 870 mag tube because I attempted to remove the two dimples by drilling the dimples out with a ¼" drill bit and dremeled the inside to try to remove the burrs and I guess I don't have the touch because my mag follower wouldn't move freely and kept snagging no matter how much I tried to remove any burrs. It's driving me insane but wait, it gets better......

I also tried to install a Slimline Tac Star 6rd side saddle and all was well until I brought the foren backwards and realized I needed to lose about 2" of the rear portion of the forend to do it, which went pretty excellent by my standard and felt pretty good about it until I put my needle nose to try and remove the lock nut from the forend tube and when I couldn't do that, I just cut it off the way it was and I didn't think I damaged anything but I guess part of the threaded portion of the slide tube got a lil deformed, but I straightened it all back out (I thought) but now I have a shotgun that takes about 30lbs of pressure to rack and a follower that gets stuck.


I am not good at this, I have the tools and I thought I had the know how but apparently I suck and this 870 is almost dead to me, I'm about to toss it to the river, does anybody have any tips or advice. I don't really have any gunsmiths in the area otherwise I would pass it off to them, it really seems like such a simple thing but has turned into a nightmare. To make matters worse I don't have a card to order anything because I'm waiting for a new one because someone in California was kind enough to rack up thousands of dollars worth of charges.... smh.
 
You may not be able to get anything new from the new RemArms company. The old Remington company who made your gun is now dead. I recently bought a new 870 and they didn't include the correct choke tubes. When I contacted them about getting a new tube was advised that at the present time, they had no spare parts.

I'd take what you have to a competent gunsmith. Chances are good he can fix your issues without new parts. And if you need new parts, he may be able to locate some faster than you. There are some places that sell used gun parts.
 
This place might have one...

Or GunParts Corp.com


But from what I understand, removing/replacing the magazine tube on an 870 is a gunsmith/factory procedure as it's silver soldered into the receiver and a barrel support soldered onto the mag tube. If you had trouble removing tube dimples and a forend, I'm not sure I'd want to tackle the tube replacement.

Well honestly I was drinking a few beers and rushing while getting eaten alive by biting flies and just got really frustrated. I'm thinking a like 7/8 wooden dowel with 220 grit and grinding and polishing the first couple inches of the internal threaded end of the mag tube or going to the dremel again with a steadier hand and more time might prove to be a more successful endeavor, I can't screw it up any worse I don't think....
 
By all means, save the tube by smoothing it up inside.
A surprisingly small amount or left over metal from removing the tabs can prevent smooth follower movement.
Just take you time and get the inside smooth and leveled around the area the tabs were.

Replacement is a MAJOR gunsmith/factory job that requires a special support jig to insure the tube is straight.

Replacement requires stripping everything out of the receiver including the shell stops and the ejector assembly.
The receiver is heated up to near-red heat to melt the brazing that secures the magazine tube so it can be removed.
A new tube is located in position with a special jig that insures it's perfectly straight in the receiver, or the barrel may not go on, or the gun may shoot off.
The new tube is brazed in place.
Then the ejector is riveted back in, the shells stops are riveted in, and the entire receiver and tube are refinished.

So, magazine tube replacement is an absolute last choice.

Yikes, I would have never guessed it was such a major deal. But tonite I got everything in good working order, first I wrapped a bit if 220grit around a ⅞" wooden dowel and that wasn't cutting it so I chucked a 12ga brush into a drill and wrapped it in 220grit and that smoothed it out. Later I'll polish it up and maybe touch up blue the inside of the tube.

Please tell me this isn't your nice 870 TB.....:what:

Like dfariswheel says, Remington magazine tubes are brazed in, they basically had to be sent back to Ilion to get it done.
Glad you were able to mitigate the damage.
 
I have a couple of 1100’s, and was advised by my primary shotgun gunsmith….buy what you can find at decent prices so you have some part guns

Should work for 870’s, also….

NEVER!!!! :D

In any case, my TB is old enough to where Remington wasn't doing the dimpled mag tube and has the old style metal spring retainer ring thingy.

Nah, the one I'm working on is an older express. I just put a Tac Star 6rd side saddle on, I'm pretty disappointed because it's nearly impossible to even get a shell to fit in the saddle, unbelievably tight, I even had to check to make sure I didn't accidentally grab a 20ga saddle. I'm going to make a thread on that, see if I'm supposed to cut each one down the middle or something, but that don't seem right but it may be what I have to do to make it work.
 
Post_11,
On my old 4-round Tacstar, I noticed the polymer holder part of the side-saddle is directional, whereas the 12 gauge shotgun gun rounds will fully seat the brass from one direction but not the other. I can only assume Tactstar designed it that way for folks who might like brass up vs down.

The polymer section can be screwed onto the aluminum plate either way. Tacstar could have changed its polymer mold over the 20 years or so, however, since I'd bought my Tacstar side-saddles which are still being used.
 
Use an appropriately sized (oiled) socket slid down the mag tube and gently tap it into the problem area. You may have to tap around the area (the holes) that is giving you problems from the outside as well. Just light taps, not herculean whacks. Tapping the socket down the tube may "iron" out the issues. I did mine years ago on an Express and used a drill, dremel, socket and small hammer. Finished it out with needle files and cloth sandpaper.

Mine works fine and never gave an issue. You'll get this.

Remington has no parts and virtually no customer service either. I'm a Remington armorer for my agency and let's just say I'm glad I stocked up on what parts I was able to snag.
 
Yeah I thought I had it all ironed out but after running the gun a bit my follower snagged up a bit. I'm curious if I need to do some more sanding, polishing and perhaps a metal follower instead of plastic....... I'm now getting why Brownells sells that tool that I thought was stupid at first, it seems pretty straightforward and hard to screw up, but somehow I managed to do just that

I rushed the process but I'll figure it out, hopefully without damaging anything or creating a reliability liability
