Frequently Asked Questions About CAA MCK

CAA USA designs and manufactures The MCK (Micro Conversion Kit), the  world’s most popular handgun conversion kit for more than 125 handgun models, so far.

The CAA MCK is shorter and lighter than any other ‘imitation’ short barrel rifle and gives shooters carbine-like accuracy from a handgun. Our CAA MCK accessories improve accuracy, grip, aim, and balance, allowing the user to be fluid, consistent, and lethal.

Many new pistol users still ask, “What is the MCK?” The answer is not super complicated—The Micro Conversion Kit is designed as an extension to your handgun and can improve the performance of your Glock, Taurus, CZ, Sig, Smith and Wesson and a growing list of other gun makes and models.

Using MCK accessories improves shooting performance and drastically improves your handgun experience. The CAA MCK conversion kits are Proudly American made in South Florida and are easy to use and require none or very little modifications. Features include:

  • Put your pistol on steroids—The MCK kit increases the stability of your pistol by a substantial amount, while the ergonomic design and ambidextrous usability ensure a more secure grip for both left and right-handed shooters. Reloading time and assembly/disassembly times both also improve significantly.
  • More Customization Options—The CAA MCK offers customization options that would not have normally been available with your pistol. You can personalize your gun with anything from scopes, slings or sights.
  • Effortless Use—This Micro Conversion Kit’s biggest advantage is its simplicity and effortless assembly and disassembly. The versatility of pistols that fit your MCK conversion kit, as well as the ease-of-use design, ensures our kits have worldwide popularity. Lightweight and portable, it is easy to carry anywhere and makes one-handed use a breeze.

These general features are just a scratch on the surface of what your CAA MCK advanced kit can do for your pistol shooting experience. But that is not all, here are a few more reasons why your pistol needs a MCK:

  • One model fits various pistols
  • It is one of the fastest methods to insert or remove a pistol since the charging handle stays within the conversion kit
  • The slide release is exposed
  • Improved ergonomics

  • Extended stabilizer brace included

Which is better, stock or stabilizer? It all depends on your needs and expectations and how far you want to take your pistol modification. But first – what is the difference between a stock and a stabilizer? Stocks are designed to absorb recoil by being placed against the shoulder, while a brace uses the arm to stabilize your weapon. When it comes to operating and function, there really is no difference between a SBR and a pistol stabilized by a shouldered arm brace… The only difference is in the legal definition of the weapon.

  • CAA is the exclusive licensee of the SB Tactical stabilizer brace for handgun conversion kits.
  • The NFA Stock requires you to register your pistol as an SBR at a cost of $200.00 with the Bureau of Alcohol, Tobacco and Firearms with a tax stamp.
  • By fitting an NFA regulated stock on the MCK, your pistol changes its classification according to the National Firearms Act
  • Using The MCK Extended Stabilizer ensures that your pistol is classified as a pistol under the ruling of the ATF.

At CAA we believe that perfection can always be improved on, and that is why we introduced the MCK Generation 2 conversion kit for handguns, and why we are already busy with Generation 3. Although the MCK 2.0 is visually similar to the original MCK, it has a number of advances and new features for improved usability.

Here is why the MCK Gen 2 is better than the previous version:

  • The design for the Gen 2 MCK features an extended stabilizer that lets you fire it even when locked and folded – what’s even better is that it’s Gen 1 compatible.
  • The rear door of the Gen 2 MCK can be extended back by an extra 15°, which makes inserting and removing a weapon much easier.
  • A new charging handle offers more surface contact with the rear of the handgun slide.
  • Suppressor height sights can be mounted on the Gen 2 MCK.
  • It features a top Picatinny rail made from aluminium for improved stability, durability, and accuracy.
  • CAA USA’s new brass catcher is designed with our new generation MCKs in mind and is sold separately.
  • There is an improved magazine holder that features a mag catch and magazine release button.
  • A suppressor up to 1.38″ diameter can be easily accommodated on the Gen 2 MCK.

A malfunction such as Failure to Eject (Stovepipe) could be caused by a number of factors:

  • Ensure that your handgun is properly seated into the charging handle. The serrations on your charging handle should align with the serrations on your firearm. Make sure your weapon is all the way to the serrations at the back.
  • Still having problems? It has been noted that ejected brass can hit certain optics, if this happens move it forward or backwards on the picatinny rail.
  • Make sure that the firearm is not pushed forward and locked at an angle when sliding it into the MCK. In order to lock on the picatinny rail lock inside the unit, the handgun should remain level and straight as you push it forward.

You can call one of our Sales Representatives or Customer Service to walk you through a solution via phone and/or email if none of the above work for you.
