I finally got my bushmaster w/ RRA "youth" stock to the range today. It's a wee bit short for me, but that's ok, since I got it for the purpose of contributing to the nonconformancy of minors.
It's supposed to be the same length a a telestock, collapsed, but it's postban legal. In prone, it works nicely. In sitting or offhand, it can be aggrevating. If I have good sling tension, the buttstock almost floats at my shoulder. For comparison, length of pull is actually about 1" shorter than a Cricket (22 youth gun. Go get one if you don't have a Chipmunk or other 22 single shot youth gun. They're barrels of fun.)
That said, yeehah! I had fun today, it's been seriously way too long since I got any real trigger time.
