1. You can build/buy a regular .223-style AR15 and:
a. Add a complete .22 upper (more accurate) or
b. Buy just a .22 conversion-kit
or
2. Buy a dedicated .22-only rifle:
a. Colt
b. Smith & Wesson
If I was choosing a dedicated plinking rifle in .22LR only, I'd buy the S&W .22 - the Colts (made by Walther) seem to have had some teething issues.
