I'm curious if anyone knows of a rear sling loop that had a picatinny rail instead of the sling loop?

When zeroing in my ARs I prefer to use a bipod and monopod rather than a bench rest. I find this to be most stable for me. I have an extra CAA stock lying around and I want to adapt it to attach a monopod to so I can swap out my stock just before zeroing in my ARs.



So far I've only seen this Luth-AR CTK - Rail $32.90


It's intended to be installed on the MBA-1 & MBA-2 stocks like shown below:


I'm not sure IF or how well that part would work to replace a standard rear sling loop and I'd prefer not to spend that much if possible. If I had to spend a good deal of money then I'd rather buy a cheap stock that has a picatinny rail on the bottom (if one exists). Any ideas, please let me know!

I believe some flavor of Magpul stocks have the ability to mount their short rail sections to the bottom of the stocks, maybe the moe rifle stock.

Yeah I believe that one does, but that stock is not a quick swap. Most of my ARs have telescoping stocks which are a very quick swap. I was hoping to find a way to attach a picatinny rail to the bottom of one of my spares. A quick swap and I'm using a monopod.
