Best backyard plinker for small little girl

Hey guys I asked before about this but was looking for a backyard plinker/hunting airgun for my little girl. People suggested a few and i ended up realizing they were all too big. What is the smallest lightest wood stock pcp or bulk co2 I can get with the absolute lightest or smoothest bolt just for backyard plinking? I can modify parts by lightning the trigger or replacing parts. I was thinking qb79 in 177 but have no idea if the bolt is sticky or hard to deal with. I can fill it for her but then want her to operate it on her own. Any suggestions are valid but id like to keep it under 300 if possible. Wood stock needed so i can cut it down for her. Ty
 
Her strength is pretty low. Shes only 6 and small for a girl. She is capable of operating her savage rascal 22lr but we cant do that in the backyard lol. Pumpers are not a consideration she just doesn't have the strength. I bought her the small pink crosman pumper and was disappointed that she couldn't work it. I like the idea of the 1077. Ill look into that. 
 
QB , if needed put in a slightly lighter hammer spring - tho it is cock on forward motion if that matters-.

I do think this QB was this young man's first competition rig

Chopped stock running on carts, he may have used an AA of some sort 3 years later at the Nationals?

Crosman 2400KT. Light, accurate, CO2, easy bolt, short length of pull.

If you want to go .22, the 2260 is a great rifle with a wood stock that can be shortened

Both can be quieted down with moderators

A 2240 was my first thought as well. A custom shop made one she helps pick out the features one could be fun and it is something that she won't outgrow as it can always be converted back to a pistol. The only issue is the grip is pretty big for a small kid and length of pull can be hard to adjust unless you use an ar stock adapter.
