recommend a sling to loop over barrel for airgun

[mazzgolf]

I have a Benjamin Titan NP air rifle. I like it a lot, but this thing is Heavy with a capital H. It doesn't come with any forward sling loop (and the way the forearm and break barrel is, there isn't a way to attach a sling loop) so I can't attach a swivel up front. So I need one of those slings where the webbing just loops over and slides down the barrel (I've seen this kind of sling for shotguns as well as air guns).

I tried some quick google searches and all I found was this Gamo one - but that loops over the stock as well as the barrel (which seems stupid, and looks stupid, to me). I want a sling with a rear swivel but with a forward loop that can slide over the barrel.

Anyone know where I can get a sling like this?
