I have two (2) ladder rail covers for sale. They are Ergogrips, and came with my DD rail. They were on it for 2 outing to the range and were replaced with Magpul XTs. They are both black and uncut.
I also have two (2) used USGI 20 rd mags. Both have aluminum followers. One is an Adventure line with 70% finish remaining, and the other is a Universial Industries that someone (not me) painted black. I was going to refinish it, but lost interest. My loss is your gain. $20+shipping.
