Marlin 99 M1 jams!

[Charles Lowry]

I bought a Marlin 99 M1 many years ago. It was my favorite .22, and would be again if I could fix it. It jams every time it's fired. And the way it jams is strange to me. It doesn't stovepipe. When the bolt comes forward to load the next round, the bullet doesn't chamber, but hits ABOVE the chamber. It does it consistently, and it went from shooting fine to this constant jamming all at once.

Does anybody know how to fix it?

My second question is this: The reciever is some sort of alloy. I was told by a gunsmith that that was the problem, and the rifle was essentially no good. I don't want to let it go for sentimental reasons. The reciever and action look remarkably like a regular Marlin Mod 60 reciever and action. Would it be possible to get another Mod 60 reciever and replace the whole thing on the Mod 99 M1??

Thanks!

It's hard to find a 22 autoloader that aint got an alloy rceiver. Have you cleaned the gun real good, spray it out with Gun Scrubber? The feed throat is a common problem, Numrich probably has them in stock.

It's not the receiver. Clean it and look at the cartridge lifter. Gunparts has 99M1 parts.

Marlin M99 jams

"When the bolt comes forward to load the next round, the bullet doesn't chamber, but hits ABOVE the chamber"

My second gun (when I was fifteen) was a M99G (Marlin Glenfield)
forty years ago, Forty-two years ago. Anyway, it sounds to me like
you have worn out the feed throat. I did that after about 20,000
rounds.

The feed throat is cast aluminum with a hard crhrome finish that wears
well until the chrome is worn through them the aliminum wears in a hurry.
When worn, the cartridge will start off too high and hit above the chamber.

The feed throat has changed over the past forty years and a replacement
should be ordered by serial number range. I ordered from Marlin Firearms,
Service Division.

The reciever is some sort of alloy. I was told by a gunsmith
that that was the problem, and the rifle was essentially no good.

Yeah, that rifle is just no good. I own two and gave another one to my son,
and Marlin has sold millions. Seriously. The Alumnium receiver holds up fine.
