Hey guys I'm having a hard time find a part that is labeled to use with the A2 full stock for mounting a single point sling. I see the end plates with loop like I need but they all say for collapse-able stocks (buffer tubes). Any option for using an A2 fixed stock with a single point sling? I've seen the ones that are just nylon straps... looking for something like the end plate setup. Thank you! P.S. If I could afford it with all the prepping and what not I would have a collapse-able.
