no issue at all, with the stock all the way up, shorter than a youth/compact stocked gun. A standard youth stock is still too long for i imagine most 6yo. Right now, he's on a psa midlength 16in stainless upper with the lightweight forearm. He can move it around the shooting rail with ease. Topped it with a leupold 1-4. We are 3 for 3 with the federal fusions.

My 9 yo has graduated into a model 7 youth in 7mm08. I loaded up some youth loads from the hodgdon site and very little recoil. Kicks less than my 243 with those loads.
