Just picked up a SS VTR in 308. Harris Bi-Pod and Picatinny rail standard. Pleased that it has 10" twist because I have more 150s than another other weight. Got the Nikon M308 with Nikoplex. If this one shoots as well as the one I gave my son, I'll be happy, happy. He put a Magpul Hunter on his, so I'll be doing that after Christmas. Don't know about their lower for 10 round mags, so anyone have any experience with it?
