Apologies in advance for the long post. Here's the problem - I don't know much about the state of the industry and the models these days, and I'm hoping someone here might have significant recent experience in the area of teaching youth shooting with airguns to be able to tell me what the most appropriate air-rifle under, say ~$150, might be for a 7 year-old. Hopefully something that will last, too. I see lots of models, but most of the ones I'm seeing labeled for youth aren't much better than the cheap Daisy models I had as a kid, and I'm sure there must be better out there. That said, I'm concerned an "adult" model is going to be ergonomically incorrect for a child of his stature (he's a little tall for his age, but not ridiculously so), with a stock that is too long, pump too hard to actuate, etc. I'd also like it to be scope-ready at minimum, and ideally come with (a decent) one. In addition, I'd prefer it not be a CO2-model so as not to have to deal with the expense and limitation of running out of propellant, but I'm willing to consider it if that's what it takes. I have ZERO intention of him doing any hunting with this, but I'd also like to be able to get a decent range out of the thing with a flat trajectory - at least 25 yards or so. From what I'm seeing, a bi-pod mount is probably asking too much. I find, for example, a "Crosman CYT6M77 Spring-Powered .177-Caliber Youth Break Barrel Air Rifle With Adjustable Grow-With-Me Stock", but it lacks mounting for a scope, and lists no FPS. Then there's a "Ruger Explorer Youth Break Barrel .177 Caliber Pellet Gun Air Rifle" that does supposedly have an 11mm dovetail rail, but I can't see where it would be unless it's what the rear sight is mounted to, which is WAY far forward for having good eye-relief, I should think. Also, it's a mere 495 FPS. Finally, I find an "Umarex NXG APX Multi-Pump Pneumatic Youth .177 Caliber Pellet or BB Gun Air Rifle" that looks a decent choice maybe, but the reviews are... iffy, and they all seem to say to throw the included scope in the trash at minimum, defeating some of the purpose. There's a Bear River B1155 model that seems to be meant for youths, but is not in stock anywhere I look, and there doesn't seem to be a significant difference between it and the "Sportsman 900" adult model. All of the above have some pros and cons, I guess, but none of them (except maybe the Bear River) seems a particularly good choice. Or am I overthinking this? Would a standard ("adult") model be just fine, with or without scope? Both my kids are tall for their ages and growing like weeds, and for my oldest I'd like him to get at least a few years' use out of it before he's ready to move on to .22LR, when his little brother (who will be turning 3 reasonably soon) can hopefully inherit the air rifle. Regardless, I'm looking for something I can teach gun safety and marksmanship with - not a toy - but also isn't going to "break the bank". Still, if there's something genuinely good for youth shooting, I'm willing to consider spending a little more to get a quality product that will last. Any help or suggestions would be much appreciated, particularly (but not solely) if you've got active experience teaching youth marksmanship.
