On a side note, while they are a hindrance at times, I would strongly recommend that your friend invests in a sling for his M14
@Lozart so that he can keep it with him under more conditions. I'd also advise standing it up against stuff where it is unlikely to fall over so that it is less likely to be kicked/trodden on. While I don't think it is the case in this instance, a lot of face protection limits the player's field of vision more than people realise and as such their awareness drops massively.
