Hey y’all.

I’m looking at getting into the PCC arena again. Last one was my BD38 (MP40 SSD Repro) that the RCMP bought back from all who owned one in Canada back in the day.

Played with a JR Carbine today and it felt pretty good (Standard Black, M-Lok handguard etc)

Are these getting good reviews? Anything I should know? I’ll be using factory Glock mags if I decide to get one.

Talk me into or out of one!

Cheers!
 
The 9mm versions I and 2 buddies had were superbly reliable. Well over 10k through each without a single feed/extract issue. One buddy stripped the charging handle bolt, because the idiot used the wrong size allen key and tried to tighten it about 4x more than needed, but that was the only issue any of us had. They aren't ammo picky, the cheap Korean mags worked just as well as Glock mags, and recoil is as soft as velvet.
Ergonomics aren't as good as a FX9 or Raven, no last round bolt hold open which is mildly annoying, amd the factory trigger wasn't great, but they are solid and well made.
 
Make sure you have blue threadlocker when cleaning. That way you don't have to go all silly bugger torquing the screws.
You'll also need an AR-15 wrench to remove the buffer tube to get the bolt out for cleaning.

Those look friggin awesome!

OP the JR carbine is truly a to hell and back carbine

My only qualm is it doesn't have last round bolt hold open

I'm over 5k rounds in my mlok 9mm version and have only cleaned it twice, never a hiccup never anything ( and about 3k rounds are cheap aluminum blazer brass ) never an issue as everyone sais running aluminum in carbines.

Everyone should buy one before they can't anymore

Thanks - that info on aluminum ammo reliability got me interested (I'd previously dismissed JRC as having no USP).

That is a HUGE endorsement. 5K rounds with only 2 cleanings? Forget 5000 rounds, I have to clean my FX9 after 50 rounds. I my have to look into these again. Assume yours is in 9mm? Any magazine preferences? Obviously if I can get away with using less Glock OEM and more PMAG, and such that would be good. Any issues with KCI/SGM mags?
 
They are reliable but certainly nowhere near a “hell and back carbine”. Had the Jr, an aero, pc9, and an evo. Shot the keltec and some 9mm ar’s. Prohibs aside I’d take the ruger over the jr. The design choices make it feel somewhat of half assed.

I will have to say, that charging handle retention was the main reason I didn't look into one seriously, originally. I had a Keltec Sub2000 that was kind of like that with the notch and mine actually occasionally un-notched itself with movement...never was crazy about that system.
 
Many 9mm PCCs on the market now could arguably be better... The Ruger PCC9, The FX9, maybe the new Lockhart carbine..... but ultimately I'm too afraid to make the switch since my JRC has never let me down. The only feature I wish it had is a last round hold open. Accuracy wise it seems to spank most other PCCs on the Canadian market. The build quality on them is excellent as well, very robust feeling. The disassembly is lackluster compared to its competitors but I really only clean it once every 1000rnds.

It is interesting about the cleaning intervals. Isn't the JR a blowback system? If so, I guess not all blowbacks are made the same. The only reason why I clean my FX9 every 50-100 rounds or so is because if I don't I start having performance issues. The FX9 also needs a lot of lubrication in order to run optimally.

The JR's disassembly can't be as convoluted as the Ruger PC Carbine can it? Requiring separate tools, and having that insane 65 inch pounds of torque for some of the screws (yep the manual even says this).

The combination of good accuracy coupled with a lengthy between cleanings interval seems to be pretty compelling, and make my typical requirement of a last round bolt hold open, perhaps a moot consideration given the other positives.
 
It is a blowback system yes and will get dirty pretty quick although mine ran dirty fairly well too. Perhaps the tolerances on the JR are larger and more forgiving but still I’d notice issues after a bit. That said for being a range toy it was acceptable. I find anything more than minimal lube on blowback to be detrimental as it just collects and holds carbon. The disassembly is in fact worse than the ruger, a castle hut wrench to remove the buffer tube, two different allen keys for the bolt and the upper/lower.

JRC used to offer an accessory takedown assembly that allowed you to remove the stock without the castle nut wrench. All you did was turn a thumbscrew and the stock came off which allowed for removal of the buffer, bolt, etc. I bought one and it works well but they no longer list it on their website so I don't know what happened as it made disassembly much easier.
 
Had one in 9mm Loved it. Sold it to my cousin after running 1500 rounds though it. He ran another 600-700 without any issues before he sold it off. Wife had a keltec which was #### and exchanged for another one that was also ####. I eventually got a aro survival rifle and just wasn’t into the design so I sold it off.
 
I have JR and Ruger PCC (both in 9mm)

The Ruger is heavier and definitely better built. That’s not to say the JR isnt well built, just that the Ruger is almost over built.

If I’m heading to range with limited time I’ll always pick the JR over the Ruger because it’s more fun to shoot. If it was the end of the world and I just had room to pack one I’d take the Ruger because it will last forever.

I run Pmag’s in both with no issues at all.

That would have been handy, mine was the version just after the triangular barrel and before the takedowns were offered. Would have been nice to have that feature. That’s too bad they no longer offer that.
