So i bought my son a smith and wesson M&P 15-22 for christman and now he wants to put an optic on it. He is big into the COD games so he wants an acog of course, , but im not paying $1,000 for a true acog. Will the NcStar 4x32 work for a 22? I know they arent top of the time battle optics and all, this definately isnt going to see any combat. It will be used to shoot paper and cans and stuff like that. Will this be a good choice for a 22? Any help is greatly appreciated!
