Just Right Carbines 9mm carbine. Handy and functional.


My friend from MKS Supply introduced me to the fine folks at Just Right Carbine at the 2016 NRA show and I was introduced to their line of carbines. After talking with them I asked about a test sample and it was not long after that I had one in my hands.  It seems well built, and perhaps a bit overbuilt and maybe a little unattractive. It has some weight to it but balances similar to an AR-15.


One option that is, in my opinion, necessary on this carbine is a forward grip. With the old school quad rail it can get a bit uncomfortable to grasp without the forward grip.

JRC-3 JRC-10

Six position collapsible stock that is easily removable by loosening the tension screw , a slight turn on the buffer tube and, pulling the stock and buffer tube straight back.


This carbine will fire from any Glock double stack 9mm magazine. I ran the 33 round magazine as well as the 17, 19, and 29 as well as the Magpul PMag for the Glock 19.


The JRC can be configured for left or right handed users. By swapping out a few parts it will run either way. The magazine release and safety is right hand only but aftermarket ambidextrous safeties for the AR-15 can be swapped in.


Though the bolt does not lock back on an empty magazine, it can be manually locked back to show clear.


The JRC can be broken down easily for cleaning or discreet carry. By unthreading the quad rail and removing the barrel is pulled straight out. Keeping that in mind you need to be sure you keep the handguard snug and be mindful how you mount accessories. In my opinion utilize the rail on the receiver is the most secure method.


It can be disassembled in less than a minute and reassembled in about the same time. Accuracy suffered a bit out to a 100 yards, grouping around 7 inches but consistently left, even with the sight adjusted to the limit. Adding optics could help with this but I expect this has a lot to do with the carbine being easily disassembled.

Initial Range Trip 

Stepping off to the twenty yard line it was time to check the JRC for reliability. It ships with a factory 1/2″ x 28 threaded barrel and, being a common thread for muzzle devices, the 9mm carbine begs for a silencer. I wanted to test the carbine with and without a silencer to be sure it was reliable either way. After a couple hundred rounds, many  of which were shot through the Liberty Suppressors Cosmic and Centurion, the little carbine had not given any trouble. It was time for accuracy testing at a twenty five yards.

Second Range Trip 


As I have learned the 9mm carbine is a soft shooting defensive rifle that adds a bit of heat to the 9mm defensive round. You can see the comparison ballistic test by following this link.  The fact the Just Right Carbine uses the Glock magazine makes sense in several ways. If you have any Glock chambered in 9mm Luger with a double stack magazine, it will run in the JRC. If you do not, Glock magazines are easy to come by and inexpensive in aftermarket. Since JRC also offers this carbine in .40 S&W as well as .45 Auto and several finishes you should be able to find one that you fancy. It shares a lot of the manual of arms with the AR-15 platform, so if you are already familiar with the AR this carbine is an easy transition, if not it is intuitive to learn. What really sets this carbine apart is how easily it breaks down, removing the hand guard, barrel, and stock. Though it does take a little time to break it down and reassemble, that can be useful in transporting it without drawing attention to yourself, and makes it pretty simple to clean. That is if you actually clean your guns. With the old school quad rail you have plenty of options for mounting accessories you see fit to run, but I recommend a forward grip on this carbine, it makes it a great deal more comfortable to shoot. I can see this carbine as a useful companion to your Glock sidearm when you need a little more from your 9mm in relation to velocity and sight radius.  We ran through over 400 rounds of various kinds without problems, so it did prove to be reliable.

    They are pretty crazy modular. You can even change the mag well to take S&W M&P Mags, or 1911 if running 45. I don’t know of any other carbine that can do that.
