Just Right Carbines manufactures a number of pistol caliber carbines that have an AR-style appearance (and partial compatibility) and use popular handgun magazines from Glock and Smith & Wesson. Two new models have been shown at the recent National Association of Sporting Goods Wholesalers show. One was the rifle chambered in .357 SIG that was announced earlier in the year, while the second is a new generation of rifle that features a removable stock.
The first rifle – chambered in .357 SIG – follows the same pattern as the existing models in other calibers. The gun can be had in both the Quadrail and Takedown models with Glock magazines. However, the caliber is not available for the Marine model or models that use non-Glock magazines. Finishes such as the Muddy Girl line and A-TACS Foliage are available in addition to standard black.
The second rifle shown at NASGW is the third generation of rifle designed by Just Right Carbines. The new gun will look very similar to and function the same as the current rifles. However, two significant things have been done to make this rifle worth consideration. First, the company added the ability to quickly detach the buttstock from the receiver to vastly improve the ease of cleaning the guns. According to the company, sub-$100 kits will be sold to retrofit existing JRC guns.
The second improvement is in the warranty offered by the company: these guns will have a lifetime warranty.
It seems that pistol caliber carbines are becoming more popular in the current market. You can even get them in .380 ACP if you so desire.
