.30 Carbine question
I bought a Saginaw SG carbine (3.4 million serial range) from a former co worker. It is not a collector grade gun, rather an arsenal rebuild with a 1944 underwood barrel, bayonet lug, etc. The stock was pretty battered, was replaced with a walnut replica stock last year so it looks pretty good.
I was shooting it this weekend using Win 110gr fmj, and the op-rod kept popping out from the right side of the raceway, leaving the bolt behind. I have shot this gun before with this ammo and this has never happened. I don't see anything amiss on the rod, and it won't pop out of the raceway it slides back and forth in until it is all the way back to the first cut. There does seem to be some " spring" on the rod pushing it out away from the receiver when in battery.
Does anyone have a fix, or an idea where I can go with this problem? Thanks!

Probably the tab on the op rod that goes into and slides within the race is out of spec. If its a shooter and your not worried about originality, just replace the op rod.
I had the same thing happen to one of my Garands years ago. I replaced the op rod and the problem went away.
I am also a carbine fan.

Thank you sir, I will check out what's available and give it a try! 0 -

I'd check to see if the new stock is causing any issues.0 -
I have fired it a few times since adding the new stock, but I will look at it a bit closer when I have a bit of time. It could've shifted a bit since the last firing.
I did look at the operating slide closer when I put it away the other day. It does look like the top of the "dovetail" (for lack of a better term) that slides back and forth within the receiver groove is pretty "smooth" at the top but still has the "dovetail" on the bottom.
This is my first and only M1 carbine, so I am not too familiar with it. Is this normal? By the looks of it the lower edge is holding it in place as it slides, but when it moves back to the cut in the groove it pops out.
I felt bad the day I had it out. I took three other shooters along and had the M1 garand, M1 carbine, M16A2 and and M4 out as a bit of US militaria (I don't have an M1A...yet) and the dang carbine failed from the get go. At least the other guns worked like a charm.0 -
I hope you can fix it with an op rod.
There was one here whose rod would jump the track.
Close examination showed the receiver rail was cracked and bowing.
An all-Winchester carbine, too.0 -

Riomouse911......once you get your Carbine running right you will love it and it will "go" just like the other rifles you mention here. A friend and I were chatting just yesterday about the home defense value of the little Carbine....it makes a very nice house rifle....light, easy to fire, powerful little cartridge that should get some respect as it very good at what it does. Our guys in WWII loved the little rifle...as did many German troops who "liberated" many of them and used them back on our guys. Just keep working on it, asking guys on this Forum for help if you need it, and you will be happy. I have several and love each one![:)]0 -
Also, you may want to field strip it & check the receiver, inside & outside, for any sign that it's a "reclaimed" receiver; i.e., demilled receiver halves that have been welded.

The receiver looks straight, but I will caliper/ square it to make sure. I didn't ever see any welds, so doesn't look like a demilled one. the serial puts it in the 1944 built Saginaw SG era, and the 1944 Underwood barrel is of the right time and type, so it looks like the parts that were arsenal added were the milled rear sight, 3 rd style barrel band/bayonet mount, and the M stamp on the modified mag catch for the 30 rounders.
The gun is a hoot to shoot, and I was disappointed that it died on this trip. Looks like a new slide will be about 70 bucks shipped....once I can slip that under the wife's "all-seeing, eternally scouring our bank statement" eyes I will report back on the functioning of the old carbine.
Thanks again for the help.0 -
Welcome to the Club..Life-long Carbine shooter, here.. My first was from the DCM, in the 60's.. As I type, there's one ready to go, leaning in the corner.. Over the years, I usually installed an extra-power recoil spring.. All the ones I kept, and especially the ones I sold when I had my license.. I purchased the springs from SARCO, years ago.. I see Wolff Springs sells them now.. I consider one a sound improvement.. Not sure if it'll help your slide from jumping, but it will tighten the action, noticeably.. Their Service Pack appears to be a very reasonable investment..
