Default question on getting bolt tube/bolt clean

Good day everyone. I really don't want to sound like an idiot but I have to ask to find out.
Does anyone here know of a way to get the bolt to slide inside the bolt tube without a gritty sound? I've tried everything in my cleaning kit to get the gritty sound/feel and I can never get rid of the grit sound. I've tried everything I know,mutiple times with no luck.

Could it be because of the polimer serface of the interior of the tube?

Any one chime in here.

Sorry for the stupid question....

Use a baby bottle brush with some CLP on it. After a half-dozen strokes or so, wipe it out with a rag. Repeat if necessary. You also need to make sure the slots the bolt carrier slide in are clean, as well as the bolt carrier itself and the slots in the bolt body.

FWIW, the fact that the lower is polymer has nothing to do with the sound or the cleaning.

While my old M16 in Vietnam could be a bear to clean (gas impingement, my sweet asterisk!), we learned to do it because failure was too often fatal. Your 15-22 is comparatively easy to field-strip and access the dirty parts (sounds like a girl I used to want to date!). The blowback system of a 15-22 will never be totally without sound but with proper cleaning, lube, and time to get the rails and slots to "marry" it will get better.
Oh, yeah; there are no stupid questions except the ones you don't ask.

There are plenty of stupid questions. Especially on a forum with a working search. This isn't one of them. Asking about the rather obscure functions of the 15-22 isn't stupid.

Personally I used Slip 2000. But yeah you won't ever eliminate the sound totally. There may and I stress MAY be a benefit to polishing the parts on question but I would be nervous to do it myself.

If you use a very har Arkansas stone to rub the rough spots off the flats of the rails, you will notice a difference. Take the bolt off the rails by removing the recoil spring and clean out the slots with a toothbrush.
Clean everything with a high quality CLPlike FrogLube or FIREClean and follow their directions.
The difference was huge.

That's interesting. I haven't paid that much attention to the rails themselves. Now I'll have to have a look at them.

I would... When I got the paint off of mine it looked like saw marks.... Very rough... I took off just enough to smooth em down then used the dermel with a polishing wheel and some red rouge(sp?)... Look like mirrors now

Well, now that Hurricane Sandy is out of my area, I guess I'll have to take a look tomorrow. Thanks for the tip.

Did you just polish the flats or did you ease the edges too?

If you look at the black edge closest to you towards the front there are still machining marks on it... i didnt worry about those cause they dont touch the bolt

PS... sorry for the huge pics!

Can CLP damage the polymer on our rifles? Could it make it brittle in the long run?

CLP is safe to use on pretty much all plastics.

Do you own stock in the company or was this debated in a long lost thread? :-)

Neither. I was just in a somewhat boisterous mood after surviving Hurricane Sandy with no damage or loss of electricity. I guess I shouldn't have made the type-size quite so large.

After cleaning a new weapon,the next thing I always do is smooth,buff and de-burr everthing. Then "hand tune" moving parts for any gritty or stiff feeling. Get everything nice and smooth. It's the final step in "follow up" quality control.

I too do the same thing... Mostly to see how it all works, plus I can never leave anything alone.

I checked mine out yesterday. The inside edge of the rail looked like it was cut with a ghetto mill (dremel). I smoothed it out and it definitely made a noticeable difference.

You are referring to the bolt carrier rails?

My bolt carrier rails looked like they had been cut with an Oxy Acytelene torch.
After I cleaned them up there was no problem or that terrible gritty sound.

Looks like i might have to do mine this weekend. But I was kind of looking for a project where people would leave me alone for a while.

Sorry, maybe I'm confused about this, or maybe it just is not clear in this thread.

I thought that the bolt slides on the rails, but the rails DO NOT slide in the upper polymer slots. That is, there is no required movement of the rails in the polymer upper slots, other than for purposes of installation and removal.

I though the only purpose of the slots in the polymer was to locate and retain the bolt assembly. Getting a super-slick feeling when installing or remove the bolt assembly is moot. In fact, one could argue that a tight fit might be better for accuracy.

Am I confused?

I believe the insides of the rails are the portion in which others are focusing on filing and polishing. Many are probably polishing both for the hell of it.
On the other hand, having rough outer rails is not going to improve accuracy. The resistance comes from the back. It would have to be extremely tight for any real resistance to form.

*Edit*
The thread did start with how to clean the grooves in the tube to allow the bolt to slide in cleaner. But that does not effect functionality.

Maybe I'm the only one but I use a small amount of gun grease on the bolt rails and it runs very smooth plus I also polished the insides of the rails. I tried oil at first and when I switched to grease it was like night and day. You can pull the bolt back and ride it in and it strips a round and locks up no problem. Same as my M&P40, put grease on the rails and it runs 100% better.
Maybe my problem is I grew up on a farm and now operate excavators and dozers and if it moves it needs grease!

I thought that the bolt slides on the rails, but the rails DO NOT slide in the upper polymer slots. That is, there is no required movement of the rails in the polymer upper slots, other than for purposes of installation and removal.

I though the only purpose of the slots in the polymer was to locate and retain the bolt assembly. Getting a super-slick feeling when installing or remove the bolt assembly is moot. In fact, one could argue that a tight fit might be better for accuracy.

Am I confused?
No, you are not confused. As for the tight fit, that is certainly debatable, considering the is the fit of the bolt on the rails that has any effect upon accuracy - and even that is debatable.

What is being considered in polishing is the upper and lower surfaces of the rails, and well as the inside faces of the rails. Those are the surfaces that bear against the slots of the bolt body.

Actually the question was about cleaning the inside of the tube, not the grooves. The bolt slides inside the tube. There is no movement of any kind in the grooves except when the BGC is inserted into or removed from the upper.

Does anyone here know of a way to get the bolt to slide inside the bolt tube without a gritty sound?

I didn't go whole hog and spit shine the bolt, but I did use an Arkansas stone on the rails.

Since the bolt slides on the rails I thought the question was very clear.

Can someone point me to a place to get the proper Arkansas stone for the job? seems like smaller and thinner shaped would be better.

Cheaper than dirt, Midway, Cabela's, Bass Pro ... Anyplace that carries sharpening stones. The pocket-sized stones will easily fit between the rails.

That said, IMHO, all that polishing the inside of the rails does is reduce some minor bit of noise. The bolt is not a tight fit on the rails by any means and polishing, again IMHO, will do essentially nothing to change performance in any way, including bolt speed on recoil and returning to battery. Personally, keeping the rails and the slots in the bolt body clean and properly lubed is all that's really necessary.

Even though I did polish the inside somewhat, I think it's one of those "feel good" things - if you think it makes your rifle operate better, have at it.
