Currently 10/22 receivers are made from a low-quality aluminum casting
As a matter of fact, in the world of firearms,
Ruger is the master of the cast parts.
In North America, there is no other firearm manufacturer
that even gets close to their level when it comes to die-casting.
Even outside of the area of firearms manufacturing,
if you think to compete with Ruger in cast aluminum or steel,
you would have to employ the expertise of one of the best manufacturers
of auto parts or something like that.
Yes, the tolerances used in the 10/22 action are very large,
the play/clearance is HUGE (on purpose), the finish is lousy.
Ruger barrels suck sh!t (on any of their product).
However, remember that Ruger sells the 10/22 with $159 bulk price.
Tactical Solutions’ X-Ring receiver $475 usd ( over priced )
I believe that is more than a receiver
(action = receiver + proprietary bolt + recoil springs + spring guides).
