This Roni buyers guide has been updated to include a review of the CAA Roni – MCK Gen 2
The Micro Roni Glock carbine conversion improves ergonomics and boosts accuracy. Did I mention looks pretty cool too. There have been a number of developments with micro Roni’s over the last two years. I often get queries in my mailbox about the different Roni models. Now with the release of the MCK Gen 2 it becomes even more confusing. As a result, I have drawn up this Roni Buyers Guide to try and assist in your selection and purchase of a new Roni for your Glock “Safe Action” pistol. Prices have come down and bargains are to be had.

Roni Buyers Guide CAA Roni MCK Gen2

Certainly the president of CAA USA, Mikey Hartman can not be accused of being complacent with what many consider to be a damn fine product. Of course I refer to the MCK Gen1. CAA have now introduced the MCK Gen 2 version and yes there are significant improvements over the previous model. Some of these improvements have been costly though. This is reflected in the price difference between a Gen 1 as opposed to a Gen 2. Gen 1 Roni MCK is still available and still offers great value for money. I am going to cover three of the major design upgrades from Gen 1 to Gen 2 here in this Roni Buyers guide.
MCK Gen 2 Aluminium Accessory Rail
The MCK Gen 2 has a fully aluminium picatinny accessory rail mounted on top. Really well made and precisely machined this rail not only allows sights to be securely attached but promotes added stiffness to the frame. This added stiffness is clearly demonstrated out at the 45m mark where improved grouping and accuracy is easily noticeable. Some – including myself – may question that the 45m plus mark is a greater distance than we intend to use a 9mm carbine conversion. I guess old habits die hard though and Mikey as a retired Lt. Colonel who commanded the IDF Sharpshooting and Marksmanship School just couldn’t resist an opportunity to improve long distance performance of this platform.


MCK Gen 2 Magazine Release
Roni’s have always had a friction fit spare magazine holder in the fore grip. I for one have never had an issue with this and always coped reasonably well with the design. Having a spare mag holder that is engineered so well that when you insert a mag you are rewarded with a very satisfying snug click is most welcome. When you need the spare mag the release button is intuitively positioned. The mag needs to be removed from the holder after pressing the button. It obviously does not “free fall” drop out like a pistol as that would be an error in design. The mag is full and you don’t want it dropping out of reach.

MCK Gen 2 Charging Handle
The MCK Gen 2 comes with the newly redesigned charging handle. Not only does this new charging handle grab the rear slide serrations it makes more surface contact with the entire top of the slide. Furthermore there is a small pocket in the charging handle (indicated in yellow below) that grabs hold of the rear sight as well thus maximising surface area contact . The consequence is a smoother, stronger pullback and less wear and tear on the slide as well as the charging handle.

Sling & Swivel
Are you patrolling long hours or doing a spot of rappelling with your Roni? If the answer is yes then this is an essential accessory. It’s a well made elasticised MIL-spec piece of kit.
If you are vehicle-based or the average oke and have selected a Roni for home defense leave the sling and swivel out. Slings have a habit of getting in the way when you don’t need them to. Enough said.

Flashlight Torch
- Can you get a better brighter torches for less money? Yes.
- Is the CAA Roni Torch great value? No
- Do I have one on my personal Roni? Yes
It’s expensive but it fits and works perfectly with your Roni. I have tried third party lights mounted on the side rails but they just don’t cut it.
- neat and integrated into frame
- easy and intuitive to operate
- mounting point on the axis of the pistol
Cons
- Pricey

Flip Up Sights

Essential equipment for your Roni. Use these as a BUIS (back up iron sight) for a Red Dot or as the primary sighting system. The rear aperture is large and excellent for low light conditions and close-quarters work. There is a medium aperture for targets further out. There has been a redesign on these sights and the earlier models are no longer available. The new design (pictured below) is frankly not as well made as the earlier model. The upside is that being a cheaper design the price has dropped. Would you fit them onto an M4 platform? No. They are fine for a Roni.

Roni Buyers Guide – RED DOT SIGHTS

You will never have so much fun with a red-dot on your Roni. I guarantee you will shoot more ammo than you can afford and be buying a new recoil spring assembly for your Glock before you know it. The Aimpro Dual Retiicle quad colour (pictured below) is my recommendation. The two choices of reticle color for contrast against any target/background (red and green) Furthermore, there is unlimited eye relief. with a wide field of view. 24x33mm window for ultra-fast target acquisition. R2250 incl VAT


Thumb Rests
Last on the list for a reason. In my opinion a total waste of plastic. The Roni has close to zero recoil so I think the thumb rest is redundant. Save the money for ammo.
