I Have made many stocks for kids from Hogue Pillar bedded Remington Stocks.
They are common as a tactical rifle take off.
They absorb recoil better and they are accurate.
they are a quite a bit better stock than the ones you mentioned.
You can buy them usually for somewhere around $60 to
$80 , cut them off to desired length, fill the void with
bondo or fiberglass resin, and then put on a limbsaver
pad.
you can leave the pad oversize, (works great to absorb recoil) or buy a trim to fit pad, although you will need a belt sander to cut to fit the new stock dimensions.
I Actually have SA remy stocks in 10.5", 11',12",&12.5" that we use.
I Take different kids hunting so I just put on whichever size fits them.
I Have about 3 or 4 of the uncut stocks laying around I have bought over the years if you need one.
Or I could fix one up as described for you.
Call If you have any questions or if interested.
Not trying to make money here, just interested in kids shooting and having a gun that fits them.
Well thats my 2 cents.
