The target stocks are easy to find, your best bet may be to purchase a cheap 10/22 adding a target barrel and then an aftermarket stock.Grabagun has had them in stock for less than an hour a few times the past couple months. Gotta be quick once they send you the in stock email.
Luck was on my side a couple days ago. Hope to get the factory grit cleaned out of the action, and a scope mounted soon so I can give it a work out.
