Mine has 6 spot welds on the latch and I think it's a T-57. I got it to help a buddy fill out a discount amount. This was from CDNN 15+ years ago and they were not cheap even that long ago ($25ea if you bought 4). No problems and I was really impressed with the quality of the mag, especially the coating on the spring. No markings on the mag, so not 100%.
The rest of my mags are GI that I got years ago when I bought the rifle, 89-90. $5 each if you spent $25 or $50 (don't remember). These were used but decent condition, no problems. I did need to re spring some due to rust.
Then again, it was close to 19 years before I ever broke them down for cleaning. It was shortly after I joined here and they were used.
Still functional, but springs are cheap.
