MCK Micro Roni Guide (P80, Glock, and More)

Micro Conversion kits or MCK are metal and plastic hand-gun addons that can completely transform your shooting experience on a Polymer 80, Glock, and other various pistol frames.

They are also often referred to as the Micro Roni for the Polymer 80 and Glock versions.

They transform the gun into a small and compact rifle, increasing your stability and accuracy while allowing you to add multiple accessories.

Let’s look at some of the Micro Roni Kits that CAA makes for different gun models and find out if you can add your gun model to one.

Glock Micro Conversion Kit

CAA manufactures most MCK models for Glock-type handguns. The most popular one is the MCK Gen 2, which CAA makes for different Glock models in different colors and patterns.

The MCK Gen 2 is the most popular kit because it has an extended stabilizer, which is also compatible with the Gen 1. It’s suppressor/compensator ready, can fit multiple Glock models, and has easy and ambidextrous handling.

The kit features Picatinny rails on the top and side, allowing you to place accessories like sights and optics. It has a front spare magazine holder for faster reloads.

The CAA MCK Gen 3 is the company’s newest kit model, with multiple new features like the ability to accept micro red dot slide/RMR mount, a built-in cleaning solution, and two height options on the stabilizer. It also has a front adapter which protects the kit from carbon buildup, making it easier to clean.

Sig Sauer Micro Conversion Kit

CAA manufactures two types of MCKs for Sig Sauer handguns.

MCK for Sig P320

This MCK kit is designed for the 9mm/.40 caliber Sig P320. It comes in multiple colors/patterns and with several accessories as well.

The Sig P320 MCK requires no pistol disassembly. You can place the gun inside the kit and be ready to shoot. The assembly and disassembly are fairly easy and quick.

It has top and side Picatinny rails for mounting accessories and a front spare magazine holder.

MCK for Sig P365/P365 Xl

The Sig P365/P365 XL MCK is designed by CAA to incorporate Sig Sauer’s smaller, more compact handgun models.

It has almost the same features as the Sig P320 MCK, with only a few design changes. It also comes in various colors and patterns, and you can choose between an added Gen 2 stabilizer, NFA Gen 2 Stock, or a short stabilizer.

Polymer 80 MCK

At the request of its customers, the CAA also manufactured and delivered the first Polymer 80 MCK. 

This Micro conversion kit is compatible with all Polymer 80 Glock models (17/19/22/23/31). It has 2 charging handles, one for P80 slides and one for Glock slides.

This kit allows you to shoot while it is folded and locked because it also has a Gen 2 stabilizer built in.

It only comes with a top Picatinny rail and an improved magazine holder that operates on a catch and release button.

3D Gun Builder even has the P80 Micro Roni (MCK) on sale!

The Polymer 80 Micro Roni/MCK is an excellent addition to your Polymer 80 handgun, allowing you to easily mount your pistol and providing easy and fast handling in any range situation.

Taurus Micro Conversion Kit

Do you own a Taurus handgun? CAA also makes Micro Conversion Kits for the Taurus G2 and G3 models.

The newer Gen 2 MCK from CAA features an extended stabilizer, allowing you to fire your Taurus handgun from a folded and locked position. Its rear door extends for another 15 degrees, so you don’t have to disassemble your gun to install it into the kit.

The Taurus MCK is suppressor/compensator ready, has a top aluminum Picatinny which you can use to place sights or optics, and a side rail for mounting additional accessories. It also has a front spare magazine holder, which operates on a catch and release button.

The Gen 2 Taurus MCK can provide excellent stability and shooting accuracy for your Taurus handgun, significantly improving over the Gen 1.

S&W Micro Conversion Kit

CAA also makes Micro Conversion Kits for multiple S&W handguns. Their kits support the SD9VE/SD40VE S&W handguns, the Shield S&W handguns, and the M&P handguns.

All of the kits have almost identical features. They allow you to mount your S&W handgun model without disassembling it. All you need to do is place it into the kit, lock it, and be ready to shoot. 

Like the Micro Roni kits for the other handgun models, the S&W MCKs are versatile and easy to handle. They enable you to shoot quickly and accurately from any position on the range. 

The kits have top and side Picatinny rails for mounting accessories, and CAA even sells bundles of kits and accessories together.

Micro Conversion Kit Common Problems

The Micro Roni has a few issues when it comes to usability. Most users have no complaints whatsoever, but not everything can be perfect, right?

The most common problem with older Gen 1 versions of the Micro Roni is how tight the extra clip sits at the front. 

Since Gen 1 models did not include a catch and release button, the extra force you need to apply to get the clip out significantly diverts your sights and stability. Luckily, CAA fixed this issue with their later Gen 2 Micro Roni models. 

Another common problem is the plastic on metal contact that some users have expressed worries about. Namely, there have been complaints of wear in the plastic, especially on the charging handle. The gun lock mechanism is also plastic, which is prone to early failure due to kickback from the gun.
