Marlin 99M1 22LR carbine

[JimK]

Hi, I got this little rifle in 1970 for squirrel's, plinking and just fun. Anyway, I got it out and did a real good cleaning and went to the range with it today to see how it shot.
Well, the little Redfield 2-7x scope was still sighted in, but the rifle wasn't worth a sh.....it. It wouldn't feed more than 2-3 shots in a row. I got tired and honked off having to jerk that bolt back all the time. I put a new recoil spring and guide rod in it and the spring in the mag tube seemed ok. Ramp was clean so I don't know what's going on.
Any help/suggestions would be appreciated.

Did you try different types of ammo?

The action on that 99 is basically the same as a Model 60. Here's a link with some good pictures for taking that action apart. http://www.thehighroad.org/showthread.p ... adid=86314

I've got a mdl 60 from that era that feeds anything. Be sure to only use high velocity ammo.

I was shooting Fed's , 550 bricks and CCI Mini Mag's. Didn't make any difference.

I think I have six of the "M60" actions... including a couple that are
near your "class"... one with a slightly bent and mostly re-straightened
guide-rod with some dis-figurement to the spring, too... it "feeds OK"
(Fed 510), but if I MANUALLY-cycle the bolt, the cartridge feeds HIGH
and misses the chamber... pull back and let it fly and when shooting
it does pretty good... I suspect the spring between the ejector/extractor
hooks is weak, as it does not spring-back as lively as the others...
Don't know how to check, but could your cartridges NOT be feeding
into the bolt-face properly as the bolt comes forward ?
and/or ejecting when fired, due to that spring ?

also, contrary to many opinions, I keep the bolt and receiver-innerds
with a fresh-smear of GunGrease after a cleaning...
and a Solvent-Qtip all-the-way-down into the "spring-hole" in
the back of the bolt often removes a lot of crud, too.

the "THR" link is a good one with good pix, here are a couple links
I keep handy for M-60... just to keep some references together...
Good luck, let us know what works...
Also, I've never had the privaledge of handling the Marlin-Carbine...
do you have a couple pix to post ?

Jim,

I don't know if this will help but one page 2 of that thread there's a guy who says his jammed a lot until he put a layer of grease here where this picture shows.



Might be worth a try.

Also Federal bulk can be some tempermental ammo, not the first time I've seen this stuff not chamber well.

Run a patch down the magazine. It is it dirty, that might be the culprit.
When it doesn't feed, does it also fail to extract? If so, it is could be the ejector-lifter spring. One end of the spring fits on a groove in the feed throat. If that has slipped off, the spring doesn't lift the ejector lifter enough properly feed the rounds. If the spring is bent or otherwise damaged, then replace it. (Numrich or Brownell's are good places for parts)

Had a similar problem in my Glenfield Mod 60. Ejector lifter spring was bent beyond all recognition from tinkering by my son. It wouldn't feed at all. I rebent the spring to what I thought it should look like and got it to work as you described. My rebend job was not exactly the correct shape, so the ejector-lifter was only partially working. Replaced the spring and it works like a charm.

Getting the action back together was not an easy task for me because the schmatics do not indicate assembly points. After 4 hours of meditation and incantations, I figured out how all the parts went back together, then remembered that my digital camera was within a foot of my computer desk/workbench.

That's some great advice greener gave you. Wouldn't hurt to give the chamber mouth a look, and make sure the rims not dinged from the firing pin. A ding can cause feeding and extraction problems.

Thanks fellow's for all the advise. I'll check those springs and chamber out and see what I find. I used a pipe cleaner on the bolt where the recoil spring goes so I know that's clean as well as everything else. I'll try the grease, run a patch with some oil up and down the mag tube and give her a go tomorrow.
Here is a quick pic of the rifle.
Thanks again

I forgot ato add this little rascal doesn't have a boltlock so you have to strip to clean. Wonder if you could add a boltlock to it?

Hmmm the "early" or 99M1 may have a different receiver,
but all of mine have a small "indent" inside the receiver such
that you can pull the bolt-handle back and (maybe wiggle a little)
while you push and the inside of the handle has a little tab on it
that will go into the indent... thus giving a Bolt-Lock-Back.
It "possible" for the indent to be clogged/dried and in need of
solvent-toothpick work... The later (last 5-8? years) have a
Last-Shot-Hold-Open, but that is an additional gizmo on the
trigger-hammer assembly.

Jim the Model 60 and 99 have a manual bolt lock. When holding the bolt handle to the rear simply press it in towards the receiver to lock. To unlock, pull it away from the receiver and release. Here's a link to a 99m1 manual in pdf format.

http://stevespages.com/pdf/marlin_49.pdf

The later versions of the Model 60, after 1985, had last a shot hold open feature. I cannot say right now if that feature can be retrofitted onto the older versions. These were inexpensive rifles and the retrofit cost may be prohibitive compared to buying a complete post 1985 rifle.

I have the manual here and the boltlock your refering to is on the 99C. Instructions say for clearing rifle "hold bolt back and visually check to make certain the chamber is clear".
Boy, how I wish it had a BL.

this is not a suggestion, just "typing as I think out loud"...
but once you've seen the Bolt-Hold-Back I mentioned,
it would not be difficult, once you get the bolt-handle with the 'tab' on it,
to drill a shallow indent into the receiver, it would be accessed thru the
eject-port... I'll see if I can add a photo... gotta get a couple chores
done first... bummer.
FYI: the Last-shot-hold-open gizmo is something I removed from my
7000, as it WITH the bolt-hold-back made for a double-release to "go".

EDIT:
I had low-light for a closeup and it came out DARK,
I tried to lighten-it-up some, and it may be washed out on your mtr.
this is the receiver from my SS-Papoose, with a toothpick standing
in the "indent" on the back-side of the receiver and the BoltHandle
lying next to it, to show the "tab" on the inside-end of the handle. FYI...

Another thought on feeding rounds. When I was assembling my model 60 I decided to test feed by moving the bolt slowly forward so I could observe the process. Didn't work well at all. Fed well every time by flicking the bolt lever and letting the recoil spring do the work. Your replacement of the recoil spring was probably a good idea. You might want to check to see if there is something slowing the bolt down.

If the 99 schematics are like the model 60, they show a bolt release lever and a spring that attaches to the post the sear spring is on. Some vintages do not have them. I couldn't see one in your picture. It it's not there, don't worry about it. The stock and, possibly, the trigger guard have to be slotted for this.

Surprising how well the model 60 shoots when I finally got all the parts working and put on a dollar 298 scope.
