Just Right Carbines manufacture blowback-operated carbines in pistol calibers that have a passing resemblance to the AR-15 platform.  The guns are designed to use existing pistol magazines, and until now the guns have only been able to operate with Glock and 1911 mags.

Just Right Carbines is now making rifles that will use Smith & Wesson M&P magazines.  Initially, the rifles will be available in 9mm and .40 S&W.  The carbines will be available in the following finishes:

• black
• desert camo
• Muddy Girl
• ReaperZ  green
• marine (nickel)

“Restricted State” models will also be available.
