I've been waiting for my AR-10, 308, parts kit from Optics Planet now for three months. Every two week they tell me the same story. It will be here in a day or two and then we will ship it right out. Oh well. I've looked around a bit and I can not seem to find a source. I guess I'm really bad at internet search efforts. I would really appreciate your help on where to go for one. I also hope I'm in the right area to ask. Thanks all.
