"Simple, reliable, straight blowback operation"

Notice the guy moves more from the recoil of the .40 rifle than the .40 pistol.

Bought the 9mm Glock magazines model this week, and took it to the range yesterday. First impressions...

The weapon is LIGHT. Even with the loaded 33rd mag in, it is maybe 6 lbs.

It also seemed pretty LOUD for 9mm. (At least to me...) It is an open-bolt style, and it seems like a lot of sound finds it way out that open ejection port. Not prohibitive, but sounds like a howitzer compared to my old Hi Point 995.

It is accurate enough. 3 inch stickers at 25 yards with a red dot were no problem. It had a little kick to it, but I attribute that to it's lack of weight. Certainly not bad, but a touch more than the 995 (which weighs about a pound more).

The manual says the weapon has a 'break in' period of 100 rounds. I put 125+ through yesterday, and had only one odd fail-to-fire. (Round was in battery, trigger went CLICK, but no dimple on the primer/case. I put the round back in the mag, racked it in, and it fired. Got me...)

I'm not in love with the no-iron-sights, but the quad rail makes up for it imo. (I put a Bushnell Trophy red dot on it, and it felt made for it.)

If there is something about the weapon that is less than optimal, but certainly not a dealbreaker, it's the cleaning. It's not your standard Upper/Lower config for an AR. The receiver, trigger, and pistol grip are all one piece. The bolt comes out through the recoil spring hole, so every time you want to clean the weapon you have to remove the butt stock. Not difficult, but not a simple as popping out a could of pins. The bolt is simple enough. An easier clean than the 995, but a little more involved than my AR.

I paid $600 total. I specifically was looking for a 9mm AR that used the Glock mags. I'm pleased with it. 8+/10.

As a pure plinker it's never bad to have more producers out there, but I have little use for pistol caliber carbines.

I have a good deal of experience with the gun. My uncle purchased one of the first ones made.

My saga goes like this...

My uncle purchased the gun new in early September of '10 and we shot it. Multiple failures to feed. Gun came bone dry so a little lubrication aided in cycling. Magazine catch also chewed at the polymer notch on every Glock mag I used in it and the magazines locked in rather loosely. Despite this, we pressed onwards.

Gun shot ok up until about 400 rounds at which point it just stopped working (no firing pin impression on the cartridge whatsoever).

I called JR and they had me send it in. They informed me of the warranty upgrade and performed it. Upgrade included an added feedramp, different angle on the magazine well, changes to the buffer assembly, and a different charging handle.

Got an entirely different rifle back about a month later (different SN#). After cleaning and lubrication, took it to the range. Within the first magazine, the rifle would vibrate erratically when a round was fired. This happened 4 times within 40 rounds. Frankly afraid to shoot it anymore I stopped and called JR. They advised me to check to make sure all the buffer components were present inside the buffer tube. They were.

So I sent it back again....

I got it back a month later. This time fouled on the inside and bone dry again. I cleaned it a re-lubed it.

As of 3/25/11, we have fired a total of 455 rounds through the rifle without issue (230rnds. of RWS 124gr FMJ and 225rnds of WWB 115gr. FMJ). Only time and more shooting will tell if the matter is truly resolved. The good things I will say about the rifle it it is very accurate and the trigger is pretty decent.
Final impression is that the Just Right Carbine just wasn't right in the beginning but they appear to have worked the bugs out with the latest model. If you do get one, be certain it is a newer production model with all the updates.

I have been able to fire 500 rounds through ours without cleaning it and have had no failures. :)

Seems like a cool idea, if I am going to be carrying around a rifle though, I might as well get rifle ballistics with it.

I think a gun like the Sub2000 would be a better buy. Its lighter at 4lbs, comes in different mag configurations in 9mm and .40, can be found for $300 or less, is fold able for storage or carried in a pack and is still very accurate.

I used to have a Sub2000 but sold it off long ago. I was thinking about picking up another one soon but I can't think of any reason to have a semi-auto pistol caliber carbine.

I see it having potential like the old revolver/levergun combos. If one of your firearms goes down, the ammunition for it would still have use in the other firearm.
Just remember the JR Carbine cannot be used with +P ammo. So if you are running +P in your handgun don't put it in the JR.

Looks all wrong to me.

Clamshells and screws??? Who designed this junker, Kraptec?

And why use a proprietary receiver? Would someone buy another stamp just for that?

Yeah... I know it runs Glock mags... but who are these people that want to run Glock mags in a PCC/subgun???

Can you swap out the magwell quick like a bunny and use cheap, plentiful, high quality Uzi mags?

If I were to carry something with the bulk of a long arm, then I want it chambered in a rifle caliber.

BTW, those 16" barrels don't offer a lot more oomph for the 9mm and .45ACP. The powder in those cartridges weren't meant for burning and accelerating the round through a barrel for that long period of time.

I've wanted to build an AR for a while, but this Just Right Carbine has caught my interest. It seems like a good idea to have a uniform ammo supply should the SHTF. Thoughts?
I understand where you're coming from having a common ammo for your weapons but you'd be out gunned by anyone with an actual rifle if SDHTF. You would not even be able to defeat soft body armor and you'd have limited range with the pistol caliber carbine. Don't worry about the different calibers just have plenty of ammo for each.

Remember rifles are rifles and handguns are handguns. Sub caliber guns are just stuck in between. You'll end up using it to fight your way to a real rifle when you need it.

I don't really care for the Just Right from what I've seen.

I say get a Colt 6450, Rock River, Spikes, Olympic, or Bushmaster.

I still want to do a 9mm SBR project, but I have no funds to do it... I love the look of this Spikes 7.5" upper!
