Agree w/ the 10/22.
And I don't wanna rain on yer parade, BUT....
But
unless your heart is set on making your own riflestock, I strongly encourage you to abstain.
Unless you can afford to take 18 months off work, and own a woodworking shop insured for over $2 million dollars, this is what is known as:
A Very Bad Idea, my young gifted friend.
It will cost you: premature graying, frayed nerves, ulcers, a Valium addiction , inpatient psychiatric hospitalization, PTSD, years of intensive outpatient therapy, and a likely d-i-v-o-r-c-e.
On the other hand, you can simply make & sell another fine knife or two
{Run whatcha brung!}, and simply send the money to the company listed below.
They usually need 6-8 weeks leadtime.
Be sure you specify:
99% inletted, so final fitting will only take you a couple hours, instead of a couple days.<<<<No,I'm not kidding>>>>

When you call them to order, see if they also have a 10/22 BLEM that you can cut down to youth size.Get both.
JMO, as always!
