10/22 magazine issue

[RWH80]

I have two Ruger 10/22. One was manufactured approximately 1992. My first firearm I got at 12 years old. Thousands of rounds through it.

The other was manufactured 2024. First gun for my son.

I have a couple new, recent manufacture BX-25 Ruger OEM 25 round mags. They will not engage in the older rifle and fall out. They work perfectly in the new rifle. I have several of the 10 round rotary mags and they function fine in both rifles.

Is there something wrong with the older rifle? Is the BX-25 not compatible with it?

On the older rifle, is the mag actually clicking in, affirmatively, and then falling out - or is it not clicking into place?

It is not clicking into place, it is weird because the 10 rounders are fine and can be swapped between the rifles.

I don't think "older rifle" is the problem. The BX 25 worked just fine in the 10/22 Deluxe that I got for my 16th birthday in 1981 and which was made in 1980.

I am not sure what is going on with it but it is pretty frustrating when you want to blast off 25 in a row

Being a blow-back operating rifle, the 10/22 "shits where it eats." Fouling winds up in the trigger group and other places you might not expect it to wind up in or on. My first idea if this were happening to me would be to detail strip down to the bare receiver, clean everything thoroughly, re-lube with Rem-Oil or similar (anything but WD-40, which is great at gumming up works), and re-assembling. If that doesn't change the situation, then changing the spring for the magazine retention plunger will and again, if it were me, I'd go ahead and re-assemble it after detail strip and clean with a fresh spring for the mag retention plunger.

. The 10/22 uses a "finicky" spring-loaded plunger system to retain the magazine, making it sensitive to debris, incorrect magazine tolerances, or wear of the spring.

The most common cause of your problem is crud accumulation hindering the function of the magazine retention plunger.

The number two cause is a weak or broken magazine retention plunger spring. .
