If you are unsure of buyer or seller's credentials, PayPal - but not the friends&family option - is a good choice. For sellers, make sure to keep records of postage and I would recommend tracked delivery.
Black ESE sling with push-button attachment. £15+pp.
Have included photo of area where small amount of material was cut away to allow sling to sit properly on the jacket buckle. No effect on usability of sling but priced to reflect this.

May also be useful to state things like an estimated round count, when the rifle was originally purchased and what specific accessories you are including with it.
Sling paid for yesterday afternoon and arrived this morning, @Wesley92your mate might have Amazon asking for tips on delivery speed at that rate 😂 cheers!
@HitchphilEdinburgh University have an absurd surplus of the bipods, imagine they would be happy to let a number go for a very reasonable price. Feel free to drop me a message if that would be of interest.
