The JR Carbine

I purchased the JR Carbine at Nations Gun Show. The price was great: $549

I have now taken it to the range twice and ran a hundred rounds through it each time.

JR Carbine - .45 ACP

Here is the good stuff:
  • The price point is excellent at $549
  • It is easily, quickly, convertible to left hand eject
  • The bolt handle can be on the left or right
  • Controls are familiar and easy
  • The internals are simple, I like simple
  • The components exceed my expectations in quality
  • My cheap $30 DOT scope did well
  • I managed a free standing, 15 round, 10" group, at 50 yards, in 10 seconds
  • It's .45 ACP! I could deer hunt with this baby

Here is the bad stuff:
  • It came with only one 10 round Glock mag
  • The single jam was using the 27 round mag
  • When empty, the bolt does not stay open.
  • It goes, "click" when empty. You have no sense it's empty
  • To clean it requires 3 different tools plus cleaning gear
    • 2 Alan wrenches
    • An AR wrench
  • You have to take the stock off in order to remove the bolt
  • The Alan nuts rattle loose easily
  • The bolt handle and lower Alan nuts are different sizes
  • No storage in the hallow pistol grip. (for Alan Wrenches)
Even with all the negatives so far I must say I am loving this carbine. It has a little less recoil than the Beretta  Cx4 .40 I have.  I am very disappointed in the after market 27 round mags I bought. I need to find quality huge mags. I worry about how fast all the nuts work loose. maybe because it was so well oiled before shipping. We shall see how that plays out. I will withhold final judgement until the 500 round break-in is past. I am going to need another case of .45ACP!

I have purchased a suppressor for my Glock 21. I plan on threading this barrel the same. Not only will they be able to share mags they will be able to share the suppressor. I am so addicted to adjustable stocks! 

So far it's a big thumbs up for the JR Carbine.


What are my future plans for the JRC?
  • Flip-up Sights
  • An EOTech scope
  • A threaded barrel for my suppressor
  • A good sling
  • A quality hot green LASER
  • High capacity mags

--Need to find a gunsmith for the barrel threading!!

So after reading your post, I went to various sites looking for larger capacity magazines. It seems that Glock only offers 10 and 13 rounders to the Civilian market for the G21. If there is a LEO version that they make, it looks like you're gonna have to find a Police Buddy to help you out. But something tells me that's a No-Go. After-market seems to be limited also. Now you might be able to get a 13 rounder Glock mag and some of those +2 extenders and relieve some of the pain, but I think if the 27 rounder isn't working for you, you might be S.O.L. Check some of the Glock Forums, they might have a reliable substitute posted somewhere. Hope this helps.

Les,

I am analyzing the ones I have to see if they and be refined to function reliably. I need to try this one too:

Never heard anything bad about the Kriss mags.

there is a +5 base plate out there too.

Nice. That thing with a suppressor will be the end-all. You'll have to bring it out this way and be my guest at my new range. Steel targets and the freedom to shoot on the move and practice other tactical stuff.

Mag-wise, I'd go with the Glock 13-rounders and +2 baseplates. 15 rounds in a semi-auto is nothing to sneeze at, not at all.

Murph! Sounds like fun!

Be careful with +2 and larger magazine extenders.

They allow more room inside the magazine, sure. But the spring has less tension. You might need longer springs to make the magazine reliable.

I have two of the high cap mags for my KRIS'S and hope they work as good on the new JR I have ordered. With all the craziness going on with the proposed ban I was lucky to find this new one but it was $100 more which I didn't think that was bad as I see basic Bushmasters selling out in stores for 3K. I will report back. If KRIS'S still have some I will order a couple more.
