Okay, question: There's a plastic dust cover over the bolt, that seems to float inside the receiver. Midway sells spares for about $7. Should I consider that a "consumeable" and keep one or two on hand? Other than keeping the dirt out, is there any reason to fret if I lose it and want to hunt or just shoot? Can't imagine it's a vital part, considering it feels like it's made from recycled milk jugs.
Thanks.
