I ran into this new company at the 2016 SHOT Show that had a pretty interesting product. They had underfolder stocks for the popular Ruger 10/22 .22LR rifles. The stocks are made out of polymer and the arms are made out of 6061 aluminum. The folding mechanism is similar to that on the MP-40 and AK-47 underfolders. They’ll be available in straight stock for scoped rifles or with a 15 degree angle for red dots and iron sights. The best part is they’re priced at just $99.99. Check them out at underfoldstocks.com.
