Got both the stock and bipod off amazon. The bipod is the universal bipod using the sling swivel to mount. And yes it is the ATI stock, it works ok but it has fitment issues ymmv (I have some gaps around the barrel and receiver). But altogether the rifle fires good. I can hit 3-5 consistently to a frisbee sized gong at ~400yds. I didn't want the brass stackers mount since you need a long eye relief scope and you cant get very good optics that way. Also I agree with the Bolt not engaging the safety on its own. The bolts are weird and can easily be put together wrong.
