That’s not a BPV, it’s a tac vest, if anything. Probably has Molle loops and places for a cell phone, camera, some magazines or clips for the Enfield. BPV’s are meant to sit close on the body. That’s def. a milsurp Molle vest.
Was going to note the same thing myself. I have a full plate carrier with ballistic plates. Conforms a lot better without the plates in it...
