Best for the price IMO. I wanted one, couldn't find one, so built one.
Smart way too go!
Get yourself a Lower that has never had an Upper mounted. An Upper in a “Pistol” configuration. Mount it to the Lower.
You now have an AR Pistol. Buy yourself another upper in “Rifle” configuration and a stock. And you can now legally switch them back and forth as you wish, as long as the Lower was built as Pistol first, and you replace the stock with a brace.
You can get a decent Lower and Upper for less then most off the shelf ARs. And have a better rifle!
