Total newbie question. Do any of the stocks used on AR-type rifles have enough adjustment in LOP to fit a youngster? I would think it would need to be approx. 12".

the tapco 6 comes with everything you need, except the castle nut wrench, to fit a small person .. buffer, tube, spring, nut, and stock.. 70 bucks and 10 minutes to install

if i were to do it again, i'd likely buy the magpul stock with friction lock

Magpul.

Thanks.
