Yeah, I did a search (been here long enough to know that before posting). None of the threads were any more recent than 2009. A few months ago I bought a box of 25 mags, date code 3-13 with "improved USGI followers" (they are green). Have there been any changes in the last 4 years since these mags were made to negate having to switch the followers?
ETA: haven't used any yet, have plenty of PMags and other USGI ones. Was basically leaving them NIW for a rainy day.
