Yes. The Camp carbine.

H&R did not make a .22 semiautomatic pistol. The Model 25 and Model 32 were in .25 ACP and .32 ACP calibers. They were "automatic" revolvers, but automatic refers to a method of ejecting fired casings, not semiautomatic function. If you can repost with all markings and a full description, will try to find you an answer. Most H&R .22 Revolvers are moderately priced, between $100 and $175, depending on condition.
We need make, model, and condition- and it is not a rifle- it is a shotgun.
all you need is an empty water pistol and a bag of raisons
