This is a nice little youth rifle.  My 9-year old daughter loves the one that I bought her for Christmas that was $40 at AGD's Black Friday sale (they price-matched MidwayUSA) and, once we broke it in a bit (we've shot maybe 150 pellets through it thus far) and attached a cheap 4x32mm scope I had from another gun, it was producing ragged single hole groups with RWS Hobby pellets at 25 feet.  Not the small, round single-hole sub-0.15 inch c-t-c groups that an HW30 or R7 might shoot, but it's also about one-sixth or one-eighth of the price.  Although not listed anywhere I could find online for specs for this rifle, I'd say it requires only about a 15 pound cocking effort and the cocking stroke is probably 30% shorter than most break-barrel rifles, making it pretty easy for a typical kid age 8 and up to cock and shoot.
