The CAA Micro Roni Review By Jim Grant

The CAA Micro RONI for the GLOCK G17 acually makes the Glock more accurate

Micro Roni, the SBR’d Glock treat!

Alright, I had to get that out of my system before I started a proper review of this product. Command Arms Accessories, or CAA as they’re more commonly called, is an aftermarket parts company with close ties to Israel and the IDF.

CAA’s CEO, LTC Mike Hartman, is a legend in the IDF. Many refer to him as the Eisenhower of the IDF, due to the enormous volume of shooters he has trained in his more than 20 years of service in the IDF as the commander of their sharpshooting and marksmanship school.

In fact, Hartman has personally trained over half a million students in the way of the gun, and was the architect of their squad-level marksman program that closely mirrors the designated marksman role in the US military. The biggest difference being the IDF’s ratio of precision shooters to standard infantry is much higher than its US counterpart – which many consider a very progressive combat doctrine.

Which makes sense, unlike the US where rules of engagement and SOP remain the same for years or even decades in the face of an ever-changing battlefield, the IDF is different. The IDF reviews every single engagement by any of its forces, and uses the data to actively shift their tactics. While being reactive is always slower than proactive, this operational flexibility ensures hostile forces never know what to expect from the IDF.

It’s only logical that a man to influential in the development of this adaptive combat doctrine apply the same concepts to the most prolific pistol in the world – the Glock. The biggest limitation of the Glock, or any handgun, is its limited effective range. While the cartridge it fires can stay lethal past 100 yards, few shooters are capable of reliably hitting targets with any handgun past 15 – especially if they’re moving/shooting back.

So rather than reinventing the wheel, the engineers at CAA took a close look at what limits shooters from fully utilizing the gun’s potential. They found, as many have, two major limiting factors in every handgun’s design – sights and stability.

It’s common sense that the most points of contact a shooter has on a firearm, the more stable it is. Hell, the IDF preaches that a rifleman must maintain five points of contact on their rifle in order to effectively use it. While that might sound overly-optimistic, it’s a data-driven conclusion; the IDF demands its infantry maintain an 80% hit rate in the field – a number that would seem unfathomable to US police or military forces.

So how does CAA achieve their goal of extending the Glock’s range? The dominant owner of the company, Moshe Oz was the inventor of the Roni carbine chassis for just that purpose. The Roni (named after Moshe’s daughter) permits shooters to shoulder their pistol (with proper ATF tax stamp) and attach an optic. What’s interesting is that we soon found out that both of these enhancements really do help to place accurate 9mm bullets on target.

While the addition of a stock greatly increases stability, the Roni’s short sight radius means iron sights won’t allow the shooter to fully realize their pistol’s potential. Alternatively, the optic rail allows faster, more precise aiming, but without a stock most shooters can’t hold the gun still enough to take advantage of it.

Together, however, they make one hell of compact carbine.

At the time of this article, I only owned a Glock 19 which wouldn’t fit the 17-specific model supplied. So for testing purposes, I borrowed a colleague’s registered SBR third generation 9mm Glock 17, and installed it in the Roni carbine frame. Installation is much easier than on the Micro Roni’s full-sized predecessor.

First, the shooter simply removes the host pistol’s magazine, and clears the action. Then, they turn the Micro Roni upside down, depress a button just forward of the stock hinge and slide a latch forward. This unlocks a gate that retains the host pistol as well as a sled.

Once open, the shooter snaps the Glock into the sled and slides both forward until they, ‘click’ into place. At this point, the latch in the back is closed, and the Micro Roni is ready for use. This might seem confusing, but it takes less than 10 seconds with a little practice.

To uninstall the pistol from the Micro Roni, a shooter first pulls down on a pair of locking tabs at the front of the brace, then performs the aforementioned actions in reverse.

But let’s get back to the Micro Roni’s features.

At the front of Micro Roni is a small tac light that produces 500 lumens from a single CR123 battery. This small tac light secures in the front of the handguard under the muzzle almost like the way the SureFire MP5 weapon light does in its integral handguard.

The light can be removed by pulling down on a pair of tabs and rotated 180 degrees when necessary. This is because the tac-light’s ‘on-switch’ is only on one side of the lamp, rotating it switches the orientation of that on switch from left-handed to right-handed or vice versa.

Above and rearward of the light and muzzle are a pair of strange-looking 45-dgree shelves that act as a thumb rest for the support hand. These shelves are attached to a standard Picatinny rail, and can be swapped out for other accessories with the same interface.

Below the rest, is an integral foregrip that doubles as a spare magazine holder. Magazine retention is achieved by a combination of friction and a small polymer tab. To release the spare mag for use, a shooter simply pulls downward. On new Micro Ronis, extraction is difficult, but with use becomes easier as the polymer becomes broken in.

CAA also built in a safety into this foregrip in the form of a rotating piece of polymer that blocks access to the trigger. It doesn’t mechanically disable anything, but shooters who want some sort of manual safety might find some comfort in its use. Personally, this addition is superfluous, as the Glock’s trigger is sufficiently stiff to prevent accidental discharges unless the shooter places their finger on it.

Above all this is a full-length Picatinny rail and a pair of spring-loaded folding back up iron sights (BUIS). These sights are constructed of polymer and are of the aperature type which are ideal for rapid target acquisition and engagement – though the short sight radius of the Micro Roni makes them difficult to use under low light conditions.

Thankfully shooters have plenty of rail space to install an optic of their choice. Below the rail is an over-sized slide/bolt release lever that interfaces with the Glock piston within. Testing both at the CAA/IDF event and at home revealed the button to work great, but that the girth of the Glock’s grip makes accessing it without shifting the shooting grip nigh impossible.

So, it’s a good thing the Micro Roni’s slide sled includes ambidextrous charging handles that allow shooters to circumvent using the release. Constructed of rigid polymer, the sled engages every serration on the host pistols slide for rock-solid lock-up.

Further rearward the Micro Roni features a QD sling attachment point and ships with a single-point, QD sling. Given the system’s small size and light weight, this is a great addition that allows for quick weapon transition and excellent retention.

Finally, the Micro Roni includes a skeletonized polymer stock that folds to the right of the gun. It secures itself with a locking tab, and is releases from this tab like a Galil stock – which is, by pulling up on the stock when folded to release it.

When in the deployed state, the Micro Roni’s polymer stock is solid with no signs of play or wobble apparent. It provides a solid cheek weld that positions the shooter’s head slight lower than the linear layout of the AR-15/M16 rifle. When a shooter is done using the stock, they depress a large button on the left side of the gun to unlock the stock. Doing so permits it to be folded away for storage or transportation.

Overall, with an MSRP of $250, the Micro Roni adds a ton of operational flexibility for very little money. The only downside is needing to register your pistol as an SBR. Shooters looking to avoid NFA hassles, can opt instead for a brace version which is the CAA Micro Stabilizer with a MSRP of $375.

EDITOR’S NOTE – While this might seem “gimmicky” or just adding weight and girth to a 9mm pistol, using the Micro RONI with a Glock G17 I was able to get 100% hits on steel at 35 yards while getting much less than that using a bare naked Glock – so it really works. Officers who don’t have a patrol rifle, or motor or bike patrols would find this very useful if they have to engage foes with longguns or have to engage in clearing a structure. In the near future CAA will be offering the Micro RONI for other makes of striker-fired pistols and even the 1911.
