PSA 16-inch First Build with 13.5-inch M-LOK Rail

A plain 5.56 first build meant for training: a PSA classic complete lower with a PSA 16-inch mid-length upper and 13.5-inch M-LOK rail. Magpul supplies the MOE stock, MOE+ grip and MVG vertical grip, and a Triton Navigator+ FFP optic is on the way.
