no cheek wield. your not going to get consistent and reliable shots. if your taking a 22 in it is for small game. and that requires consistent and reliable accuracy. I would also go for the 10/22 ruger. The concept is nice, but I have to agree with a few it looks like a basement project.
Also the H-S Precision bolt-action take down in 300 win is a nice powerful rifle with a take down option. but with a huge price tag.
One more to mention if you can find used as there not made any longer is the Springfield's M6 which has a .22lr and a .410 shotgun over-under and holdable.
However not a take-down it definitely meets the size requirements and weight the ruger charger
Looking at a comparison
10/22 take-down approx 18" when taken down, 37" long when assembles. 4.67 lbs
henry take-down, approx 16.5" when taken down, 35" long when assembled, 3.5lbs
Springfield's M6 approx 15" when taken down, 32" long when assembled, 4.7lbs, also .410 shot.
ruger charger, 19.25" long assembled, 3.5lbs.
I think the ruger is more reliable but is couple inches longer which may not fit in some packs and is slightly heavier.
Is there a big need to keep a 22 hidden in a pack as apposed to attached to the outside where you can use a standard light rifle that doesn't need to be taken down. there are several more options one such i got for the kids is the savage rascal, 31.5" long and 2.6lbs, however single shot bolt compared with the above semi-auto, which when hunting small game can be a big advantage for quick follow-up shots.
