Anyone own a Tippmann M4-22 rifle, particularly a Pro or Elite model? I recently purchased an S&W M&P 15-22 but was surprised that one of the larger retailers in my area was stocked with Tippmann AR rifles but none of the popular 15-22. I know that AR-.22 clones have been around for years but I'm not familiar with the Tippmann brand. They are manufactured in Ft. Wayne and seem to receive favorable online reviews. Everything on their rifles is proprietary-- no Magpul parts-- and they cost $500--$600. That's a little pricey to risk on a rimfire plinker, unless it's top notch.
