first carbine unboxing

Since you've got the Mags handy, try cleaning and servicing them.
I'm not saying this is your current issue, but it's a great time to rule out a Mag being 'The Problem'.
I can say out of a mixed box of over 50 NOS and used I found issues with about 20-25% of them.

Have you had the Mags apart to clean and lube?
To check or swap internal springs?
To check for sharp corners on the side edges of the Follower and to see if the rear wall of the Follower is at 90 degrees to the top?
To see if the top of the Follower is sitting level?
Feel for sharp raw edges on the top side feed lips that may put drag on a round being stripped. I use a worn out piece of 220 to smooth the side feed lips or a fine wet rock.

Look inside the Mags Tube for scratched raw areas with finish missing. A sharp burr on the edge of the Follower can hinder the Spring, killing some energy.

I try to wipe away any extra oil from inside so it deters dirt from hanging on.
Then spray with Silicone and stand upside down to drain any extra.

Here see for yourself. Norchwich93cmp has a video on tuning mags:

Yep. I took them out of the grease wrapper, cleaned flushed all the hard grease out of em with mineral spirits and gave a good scrub in an out. dried, re-oiled, and assembled. I took a pencil and pushed down on the followers in various places. They each went all the way down, and all the way back up, level all the way no matter where they were pushed down. I did just order 2 of the new Korean made ones that people say are really good, as well as a NOS replacement mag catch of the newer type - which people are calling the m2 type but what people on this forum clearly proved was meant for all M1/M2's in ordnance dept docs.

Do your's giggle as much as mine?
