The ones I have don't scratch that easily and do drop free. I have some straight 20rd too, and I have used those with no problems. I was just going through all my AR mags because I decided to replace all the green followers with Magpuls and I needed a count. I won't mess with the CPs. It turned out that I only needed 24 followers, all for my '90s original G.I. mags. Other 30rd mags I have are the CPs, Lancer, Brownell's tan follower and a few D&H. In the G.I.s, I had replaced the black followers with green years ago when they were the thing to have - they never were that great. This whole thing started when my neighbor gave me three G.I. mags that somebody had put Magpul followers in. I was impressed with the followers and decided to clean the mags up and paint them. Then, as projects do, it grew into doing the followers in all my G.I. mags.
