I messed up...need help fixing it.

Post by GunnerGSP » Sat May 04, 2013 3:13 am

OK. My Remington 870 has not, nor will it reach home defense status for some time to come. I have other "tools" for that.

My Remy is kind of like my hot rod gun. So for fun I opted to upgrade the follower (S&J), carrier dog follower spring, and extractor. I got it all swapped out and...something is wrong.

The action is now very stiff and cycling shells is extremely difficult, especially when the carrier lifts the shell. The carrier looks to be pinching the shell as it lifts it. I can't put my finger on what else might be wrong and it persists even after undoing my "upgrades". I hate to say it, but the gun is now unusable. I want to figure it out myself, but may have to take it to a 'smith.

Anything come to mind on what I might check? I have had it apart for cleaning and inspection before and had no issues getting it back together.

My knee-jerk thought would be that you didn't put your shell carrier system back together properly. Your follower shouldn't have any effect on your action, and the extractor shouldn't do much either.

When I woke up this morning, I had a thought on what it might be. I will take another look later.

Agreed on the follower and extractor. I actually took the extractor out and put the old one in because the new one was catching. I think it needs some filing.

I changed the carrier spring just like AI&P Tactical shows in his how-to video. I may take some pics and post later.

OK. Attached are some pics of the trigger assy. I also attached links to some short video clips I took that may lend some clues to my issues here.

They say a picture's worth a thousand words. I think I see your problem right there:

The end of your action bar lock spring is sticking up, while it should be held under the top arm of your action bar lock. If I was a betting man, I'd bet money that that spring is what's snagging your action when you rack the gun.

OK. I hate to admit it, but I am feeling a bit challenged here.

I have compared my pic to other trigger assy pics posted online, and I am not sure what is out place. Do you have pic I can compare to?

I found this one and was comparing it to my pic.

If you have your owner's manual handy, you can see the parts I'm talking about in the exploded diagram in the back. Once I'm done with supper, I'll pull my gun apart and post a picture for comparison.

OK. Thanks much...

It's not so much part identification, but proper positioning I am not grasping.

This is the part I was referring to:

The action bar lock spring on my 870 fits under the action bar lock, instead of sticking up:

However, looking through other pictures online, it seems that many 870 trigger plate assemblies have that spring sticking up like yours, so maybe that isn't your problem after all. If you look at the bottom of your slide assembly, is it scratched on the left side in such a way as to indicate interference? While you're looking at that, see if you can find any other abnormal wear marks that might offer clues.

Your slide assy looks about like mine.

I have noticed the top of the breech bolt assy has wear marks I never noticed before.

I am about to throw in the towel and just take it to a 'smith.

Any other suggestions before I do?
