As I'm on the topic then perhaps I can pose a further question please?
I know from the rules that nothing can be added or taken away from the rifle during a competition.
Would it be permissible to have a single point sling permanently attached to the rifle, but not permanently attached to the shooter?
I'm thinking about adapting a single point sling so that it remains attached to the rifle but unclips from my upper bicep, leaving a bicep collar around my arm, but not constantly attached to the sling. I would like to be able to unclip myself from the sling in order to move around safely and not be encumbered by having a heavy rifle permanently attached to me.
Would that arrangement be permissible in a reasonable interpretation of the rules?
