Sarco’s Ruger 10/22 U.S. Paratrooper M1A1 Carbine Stock. Sarco sells these for $150. Comes complete with handguard and swivel band assembly. Hardwood stock/handguard and metal + leather folding stock assembly. Folding mechanism is cool and seems to work well. The stock will require some additional fitting. Although it is designed for a 10/22, Sarco themselves advertise that it takes some fitting. I started fitting it and lost interest (don't have a lot of time for hobbies right now).
