That Bi-pod looks like a few I've seen at Walmart, It looks like the 25-35 dollar version. Thats what I'm planning to put on mine, and possibly real scope as well cause I its like only ten bucks for a real one compared to that pack of accessories Nerf sells( and more accessible as well).
That's supposed to be a derivative of the Halo rifle, right? It looks pretty nice, that paint job looks close to what they have on the XM-2010, though that camo looks better. If anyone's interested here's a picture of my WIP. <[link]>
