Review: CAA Roni Civilian Pistol Carbine Conversion | Non-NFA

CAA has recently expanded their RONI line with a new non-NFA option for those that want a proper stock but refuse to file a stamp. Recently I reviewed the Lock, Stock, and Barrel carbine conversion and found it lacking in a few areas, based on a cursory look at the RONI chassis I feel like this might feel more like a rifle for those looking to turn their pistol into a rifle.

Pulling the stock out of the box a quick read of the instructions shows how to open the clam shell of the conversion up. There are two HK style captive pins that need to be pushed out in order to slide the forearm and rear portion out of the way. The kit does include an Austrian made 16″ barrel that is not pictured.

Once the stock is opened up it is as simple as fitting the included 16″ barrel into the slide, replacing the stock recoil spring, and sliding the charging handle over the rear of the slide. The charging handle has a convenient cutout for the rear sight so even if you have suppressor height sights the handle will fit. Some adjustable target style sights may not fit requiring modification.IMG_3971 IMG_3975

Now slide the barrel and gun into the stock and locate the rail slot with the stud molded into the stock. Close the clamshell, tighten the two thumbscrews and push the two parts of the stock closed so that you can reinsert the captive pins. The entire conversion takes only a couple of minutes from start to finish, the Glock 17 Gen4 that I borrowed from my friend for the test looks a little ridiculous but whatever.  IMG_3977 IMG_3980

Even though the Glock has no manual safety CAA felt it a necessity and included a crude trigger block on the RONI. You can see the thumb screw just forward of the trigger block. They also include an adjustable forward grip that you can position at 90 degrees, 45 degrees or flat against the stock depending on your preference. IMG_3982 IMG_3985

I found the mechanics as to how they made a Glock work inside of a rifle stock rather interesting. The charging handle pokes through the stock allowing it to reciprocate with every round fired. I was a bit concerned with the moving part so close to my face but quickly saw that I was in no danger of being struck. The thumb screw just below the charging handle was a real bear to tighten by hand and required a screwdriver to get to finish tightening it up. IMG_3987

I decided to mount my spare Aimpoint M4 on the rifle, I think I would have preferred a smaller red dot to the large M4. The M4 was the perfect height for the RONI, on the other optics I tried to mount I found that the stock was far too in line to go with anything shorter.IMG_3993

Getting the RONI out on the range was more of a treat than I ever expected. I sort of questioned the existence of the carbine conversion trying to figure out what role it would fill. After an afternoon where I burnt through about 600 rounds I think I have identified the role that it is most at home in. Fun at the range. Unlike the other conversion kit I recently tested I found that the Roni was more than reliable with every kind of ammo that I put into it. Everything from the cheapest steel case 9mm to the ultra hot +P+ 124 grain 9mm I had with me, the RONI ate it all.

My only recommendation is that if you plan to buy a GLOCK for the RONI or have a choice, use a Gen4 gun so that you can swap the mag button to the left handed side. The same problem that I found with the Lock, Stock, and Barrel was presant on the RONI as far as fast mag changes. Roni1 roni2

Shooting at the same 25 yards that I did with the other carbine converion I got a bit better group when shooting unsupported. I refused to make adjustments to the Aimpoint since it normally lives on one of my AR-15s and really didnt want to hassle with rezeroing. I was pleased with the level of accuricy that I was able to squeese out of the RONI when shooting at steel targets on the 100 yard rifle range. Reliable hits when compensating for the dot being a bit off was quite simple. IMG_4000

Should you give the RONI a try? Hell yes. It was one of the most fun things I have been able to test for the blog thus far. I can see the RONI fitting into several different roles from a low-cost training tool for new shooters all the way to home defense. It wouldn’t be my first choice for self-defense because, well, AR-15. But if you were looking for a 9mm long gun on the cheap I wouldn’t count it out.

The MSRP of $592 is a bit stiff, but if you already own the Glock the stock is only about 1/3 the cost of an actual pistol caliber carbine. You can learn more about the CAA RONI Pistol Carbine Conversion C-G2 on the CAA website HERE.

    That new 10mm Kriss is going to start looking worse by the day.

    • Paul White

      I don’t know; 400-500 for a glock then 600ish for this and you’re close in price.

    • Harry’s Holsters

      I think 1300 for the Vector and more cool factor. I’ll take the Vector and the $200 premium.

  • Malthrak

    At $600 on top of a $500 pistol, it’s only 1/3rd the cost of an actual PCC if you’re comparing it to the very upper tier of PCC’s. Next to a CZ Scorpion, Beretta CX4, KelTec sub2000, or even a HiPoint Carbine, the Roni is doesnt look so great on the price point for a PCC being right in the middle of this pack on its own and above all of them in cost when the actual pistol is factored in.

    It looks like a lot of fun though, and as an *enhancement* to a Glock pistol could be pretty solid, its just not particularly cheap in terms of PCC’s on its own.

    • Harry’s Holsters

      100% dead on!

      You can get a 16inch scorpion for right at a grand.

      You can easily build a 9mm AR for $750 although I’ve heard reliability can vary if you don’t get the parts combo right.

  • alex waits

    not for me.

  • thedonn007

    I would rather try the sig brace pistol version of the Roni.

  • stephen

    I tried a roni and while it was fun for a while, its in chest with other stuff I don’t play with anymore.

    With that said I would save up money and just get the Sig MPX.

  • A.WChuck

    At that price I’ll stick with the Sub2K that takes Glock mags.

    • Reef Blastbody

      Wish they made a 10MM Sub2K

      • ozzallos .

        Or 45acp.

    • Hugo Stiglitz

      Totally agree. Sub2k in your backpack or briefcase and G17 in your holster is a smarter arrangement.

    • CavScout

      Sub par made.

  • Cal S.

    Hahahaha! Yeah, sure thing, boss. I’ll gladly pour $900 into my existing Glock instead of just buying a Kel-Tec Sub2K and have two guns for less than the price of one…

    • Patrick R. – Senior Writer

      Fair enough. All I am saying is it is an option, there may be better ones out there for you.

      • Badwolf

        I get that. More options is better. But given what’s already out now, the $592 pricing doesn’t make any sense. Not when you can buy a complete pcc that takes glock mags for $500. CAA is out of touch with the market.

        • Cal S.

          When I see how much $55 in injection-molded plastic and fasteners can be sold for, I seriously consider buying a machine.

      • Cal S.

        Now, it is an interesting match-up. Sorry if that came off the wrong way. If anything, I do like seeing how they come together.

        Question, though, did you opt for the longer stock kit out of a desire to use it independently of the long barrel later? I would have thought their ‘SBR’ kit would have worked just as well and may have saved some precious ounces.

        • Patrick R. – Senior Writer

          That just happened to be what was shipped to me for evaluation. Contrary to popular opinion writers often don’t get to choose what product they review.

          • Cal S.

            Well, there goes my aspirations, lol.

          • Patrick R. – Senior Writer

            Every now and again we get to cover something we are excited about or really want to test, many times that happens when a writer buys something for the purposes of evaluation.

            The big perk of the job is getting experience with things that we would normally not buy or have a chance to put hands on.

          • Cal S.

            That’s true. It’s own reward, I’m sure.

          • Patrick R. – Senior Writer

            It really is. I have had the chance to mess with some oddball stuff for sure.

  • BattleshipGrey

    So you borrowed that pistol from a friend huh? 😀

    Thanks for the review.

    • Patrick R. – Senior Writer

      Yep. I don’t have a 17, only a 19.

  • c4v3man

    Honestly $600 is simply too expensive. It’s a neat option to be sure, but considering Scorpion Evo’s go for ~$720 as a fully functioning firearm, or ~$950 for the stock equipped 16″ model, I just don’t see the point. If this was $400 it would be expensive, but make more financial sense. At $300, they’d sell a bunch. I just get the feeling this is a big cash grab while PCC’s are selling big, but 2-3 years ago this would have sold for closer to $400. Honestly a 10mm version (which they offer in the NFA barrel-less version) would make more sense, as I’d imagine 10mm would benefit more from the longer barrel, and would compete in a much less crowded market. As it is, it seems like a lot to spend on an accessory that could instead buy a complete firearm, like a Sub2000, that would arguably be more reliable.

    • Harry’s Holsters

      I see why these cost that much but I’m not sure who the main market it. Gamers?

      • Reef Blastbody

        Yeah, pretty much. The COD/Battlefield/HALO crowd who want something that looks like it’s from 50 years in the future.

        • Ryfyle

          Nah, We all wanted the Kris KARD way more.

  • Nicholas C

    I like the one I got. I see it as an option for those who shoot USPSA and want to dabble in Pistol Caliber Carbine division. Only issue is that it only works for Glock 17 and not Glock 34/35.

  • Bill

    I just can’t figure out the angles on trying to thread a 16″ barrel through a GLOCK slide.

  • De Facto

    $592? Eeeeeeeeeek.

  • De Facto

    MP5 clone carbine: $1800+
    SIG MPX: $1600+
    Ronin+Glock 17: $1142
    CZ EVO: $1050
    MechTech+Glock: $1050
    Lock-Stock+Glock : $850
    Beretta CX4: $800
    Ronin: $592
    Kel-Tec Sub2k: $550
    Mechtech: $500
    HiPoint Carbine: $315
    Lock-Stock-n-Barrel: $300

    So.. I guess if you wanted to buy one you can.. but it only sort-of makes sense if you already own a Glock.. and if you don’t like the Mechtech upper.

    Long story short the day Hi-point starts accepting Glock mags is the day they rule the PCC market.

  • Reef Blastbody

    I’ll admit, this is a very sci-fi looking stock adapter, for the asking price, I’d opt for a MechTech carbine upper, and is also available for both large frame Glocks in 10MM and .45ACP, as well as small frame in 9MM and .40S&W.

  • Richard

    do they offer it in any other calibers?

  • jerry young

    They don’t go very much into the barrel other than install it into the slide but looking at the picture the barrel looks kind of flimsy like it might not hold up to heavy firing, by the time you add all the cost of the gun and this whatever you want to call it you can buy a 9mm carbine, it doesn’t seems worth it especially when you can build a 9mm AR for less off the books using an 80% lower

  • Rob

    Its looks alone turn me off, then theres the price. I’d sooner go with the MechTech conversion unit @ $430+ But a “real” PCC would be a better buy.

  • Budogunner

    “I was pleased with the level of [accuricy] that I was able to [squeese] out of the RONI when shooting at steel targets on the 100 yard rifle range.”

    Brackets added for emphasis…

  • vwVwwVwv

    i think the USA is the wrong place for the product.
    you have no restrictions on the numbres of guns you can have.
    in many places of the world like germany a roni
    may be the only PCC you can have
    without shrinking the gun
    numbre you are
    allowed to

    “The MSRP of $592 is a bit stiff, but if you already own the Glock the
    stock is only about 1/3 the cost of an actual pistol caliber carbine.”

    If you already have a $500 Glock to throw at this project, the $600 carbine conversion is 1/3 the cost of a pistol caliber conversion? Where are you buying pistol caliber carbines? I’m a big fan of the Kel-Tec Gen 2 SUB-2000 (street price typically $400-$500), but for a lot less money you can buy a Hi-Point carbine.

    The GlockaRONI is clever and kind of cool, but I just don’t see why I’d do this when there are Gen 2 SUB-2000 carbines that accept Glock magazines.

  • Biff Uppercut

    The Roni is garbage. I sent 2 back to the manufacturer because of various problems. DON’T WASTE YOUR MONEY!
