I bought my new 7600 Carbine 30-06 Spr. a few months ago. I've fired about 60 rounds through it. The fore-arm was nice and tight and made no noise. Went hunting with it today and the first few hours it was tight and quiet as always. Then after we made our last move I loaded it and all the sudden the fore-arm started rattling when I touched it against my arm as I carried it. Or if I put my hand on the fore-arm while it's resting as if I was going to shoot. The action seems a little smoother then it did before, but it never made any noise. If I lift the fore-arm up and down as the rifle is in the aiming position, I can see the round part of the action bar going up and down on the tube under it. That's where it's making the noise from. I made sure the big screw on the end of the fore-arm was tight.

Why would it all the sudden get loose and start making noise? Is there a O-ring or something in between the round part of the action bar and the tube under it? I like that the action seems a little smoother, however I don't like the noise it's making now. Is there anything I can do to stop it from making noise. I asked a good friend of mine that has 3 or 4 7600's. He said they get loose and make noise as they break in, then asked me if I wanted to sell it. Which I don't. I just don't want it to make noise.

Thanks, NYH1!

On the 7600 there is .010" clearence between the rear right side of the action bar and the trigger disconect. You can see it by removing the clip and looking in the bottom . That clearence is neccessary for the action to unlock , every 760-7600 have this . Yes there is an o-ring on the action tube . Your rifle is new and not broke in yet , there's no way the o-ring is worn out . I have been hunting with these rifles a long time and not one of them has ever spooked a deer , just killed them ! Shoot it some more and get used to it , you've bought yourself a good rifle , nobody has made a perfect one yet !

My rifle went from not making any noise at all to being the noisiest pump action gun I've ever heard in an hours time. Noisier then my old rattle trap Ithaca M37 and my sons little Mossberd 505 410.

Make sure the barrel nut is tight , I have seen loose ones on brand new 7600s . If I could put my hands on it for a few mins. I could probably diagnose and repair it , I have never heard most of those noises you describe ! Get yourself a nice 760 next time , better gun . IMO

That's what I don't understand. It went from tight and quiet to loose and noisy from the time I unloaded it to the next time I loaded it. . . . .a few minute later. The big screw at the end of the fore-arm is tight. The barrel seems to be fine. Just all the sudden there is a ton of slop between the action bar and the tube under it.

Maybe it was in dealer or warehouse stock for a long time and the o-ring dry rotted and fell apart , sure sounds like it . I have those o-rings if you need one , and the tools needed to install it . If you decide to DIY be careful not to egg out the holes in the action tube with your punch ( wrong tool ) . If you do you'll have to file or hammer them back down to surface height , and your gun will be forever scarred . How's the trigger ?

Ive yet to see one that didnt rattle. My brother in law loves his but hates the rattle. What he does is wrap a thick rubber band around it. He says when he pumps the action on a second shot on a deer it doesnt slow down anything

Lloyd, something definitely went wrong with mine. It went from making NO NOISE, to making A TON OF NOISE in minutes. I could deal with a little rattle like I've seem and heard on others. This is WAY MORE then a rattle. It's horrible, especially on a 2 month old rifle!

I love it and will definitely get it fixed. I'm an hour from the Ilion, NY Plant. I took a 870 back for warranty work in the past. I may have to take a ride after the season. I can use my Marlin 336C 35 Rem. or my Remington 700 Classic 280 Rem. if it bothers me to much. I've shot deer with both so it's not like I'm out of a rifle/carbine for deer season. I just really like and want to use my 7600 carbine as I set it up as my all round big game rifle. It serves that purpose great.

NYH1! ;)

Oneoldsap, where is that o-ring located? Mine rattles bad and it just started recently, I think my o-ring failed. I took off the forearm and see the holes in the action tube. Do I have to take the tube off, and does the o-ring go between that and the slide sleeve that goes over the tube? Thanks,

Lester

an other think to look at it the action bar release., when you unload the chamber,the tab you press up to open the action has a long bar that locks the action closed, it could have been defective from the factory or out of alienment. i own four rem pumps and none rattle and that incudes a older 760. eastbank.

Did ya get her fixed ?
No, deer season (rifles & slug guns) ends this coming Sunday the 11th and I've still been using it all along. It's an awesome setup. I planned on using it for hogs after deer season. I'll call Remington after the holidays and take it back to Ilion to have it repaired.

Not to jump the thread, what kind of tool do you use to unscrew the tube and who handles them? I have older 7600 and the forarm is also starting to rattle a little. Looks like the punch idea is out!! Zeak

I don't know that there is a tool available for sale anywhere . The special tool I have was made by a gunsmith friend of mine . I made a tool to spread the action bars , so that you can get them over the barrel block without bending them or scratching the blueing off the barrel block . I can check and see if he's made any more , if anyone is interested ! Sometimes you can get the action tube loosened by heating it with a butane torch ( soldering torch ) and a tight fitting punch !

I'd be interested in the tool... I cut off a screwdriver & grinded it down
