M1 Carbine feeding issue; need some opinions and guidance

I have a new M1 carbine and it shoots straight and functions flawlessly until the next to the last round. Mags are NIW Korean 15 rounders, and I've tried four different ones. Ammo is brass Aguila FMJ.

Again, the only malfunctions are the 14th round. It's always a misfeed; bolt just stops halfway. But no other rounds in the sequence ever malfunction. I put about 100 rounds through it.

Any thoughts?
 
Huh. Weird. Is there any little snag-sort of protrusion which holds the follower down? Another notion, me being me, is that I'd spray a little gun oil down the inside of one of the offending mags, just sorta "in case of in case" exploring.
 
Try taking the mag apart and putting a light coat of white grease on the spring and sides of the follower. I had lots of feeding problems with new and old magazines on mine. That solved the problem.
 
when you say "new" do you mean new manufacture like an auto ordinance or "new-to-me"? did you try any other brands of mags? they're only ~$10 so getting some different ones and trying them wouldn't cost a whole lot.

my inland that I just got is in pieces waiting for all new springs to arrive and a few other bits. if it's a GI then tear it all the way down and give everything a really good cleaning and replace all the springs and totally rebuild the bolt, inspecting everything very well as you go. remember thos GI's probably haven't had much attention since being rebuilt right after WWII so it's common for parts to be worn out, like the recoil spring for instance. also take apart the mags and clean and inspect really well. while they're apart give the springs a gentle stretch and see if that helps.

if it's an auto-ordinance and it's still under warranty then make them fix it.
 
I will reply assuming this is an original.If it is lets assume it ain't the rifle's first rodeo.As a veteran,it worked.A Wolf replacement spring set is likely a good idea.
The 14th rd thing is interesting.I do not know what to tell you.I thought Aguila made good ammo but another TFL member traced his problem to Aguila ammo in a carbine.I think Fiocchi makes some,you might try it.A little tan lubriplate in the cam area,bolt to slide,is good.
You do not want to hold the mag like a handle on a carbine,let it hang free
 
My AO Carbine would sometimes fail to fully extract. Extractor was ok, it just didn't pull it all the way out of the chamber. It did it with any mag's I used, and different types of ammo.

I got tired of it, so I coated the bolt and top inside of the receiver with Flitz polishing compound and put two 15 rd. mag's thru it (I load 14 like you). Have have had no trouble since. I just smoothed things out a little faster to help break it in.

Sounds like the round is going into your chamber OK. Just not far enough. Similar to mine extacting, just not all the way. Maybe some polishing will help, as it did in my case.:cool:

I'd try other mag's, also. I bought all my magazines from Auto Ord.

And it feeds DPX just fine.:D

That really is odd... the only thing that comes to mind is possibly an issue with the follower(s)?

One way to determine the problem is to eliminate the parts in question one part at the time. Take a known-good magazine (USGI perhaps) and swap parts one at a time(follower, spring, mag body) with a Korean mag until the feeding issue is resolved.

Still... 4 mags all doing the same thing? weird
 
A Wolf replacement spring set is likely a good idea.
Click to expand...

except for the extra power recoil spring. I've read those cause more problems then they solve. wolf usually makes good springs. just make sure the new recoil spring is new manufacture and rated the same as original.
 
Only issue I ever had with an M1 Carbine is a bad mag. That is not the case here -- it is obviously the GUN.

Are you watching the rounds feed and extract by hand to see what may be different about the 14th round? This WOULD suggest the follower is being effected by the gun. Look carefully. Something's changing at that point, and be safe!

My $0.02.

I love the M1 carbine. However, I've never known any of them to NOT have feeding issues. If you run a check on all the M1 carbine threads here, you'll see what I'm talking about.
 
I took mine out right after I got it and it only had 1 failure to eject out of 50 rounds of remington SP. that was before I did anything to it. right now I'm waiting for my new springs and extractor. should run fine when I get it back together.
 
Terry,there were a great many of them made that fought for decades all over the world.Arsenal maintained,not worn out,with good mags and ammo,clean and lubed,they work just fine.I am not basing that on something I have read here.We had $50-$75 dollar carbines and 7 cent good ammo.
I have shot a number of them a whole bunch that ran just fine.
 
Thanks guys. It is a new AO Paratrooper carbine. Everything fits fine and it shoots great except that next to last round. I'll play with it some more next weekend and see what I can find out.
 
I just had my old WW2 vintage CMP M1 out this morning. Greased mags and Remington ammo. Not a single problem. When I used the Privi ammo, lots of problems. This one likes the remington. Hope you get it sorted out. Really fun carbine to shoot.
 
UPDATE:

It was an ammo issue. I was using Aguila, and I think with a new, stiff spring the bolt wasn't coming all the way back and the case rim was catching on the follower just enough to slow the next to last round (it rests on the rise in the follower).

I ran a box of Remington 110 gr MC which were noticeably more powerful and I had absolutely zero malfunctions with a GI mag and two Korean mags from the last trip. She appears to be corrected. I will run several boxes of the Remington through it before trying the Aguila again.
