Frequently Asked Questions

What does NFA mean?

NFA stands for National Firearms Act of 1934 and it regulates short-barrel rifles (SBR), full autos, suppressed guns, and other weapons. If you buy an MCK with a stock, it’s an NFA item.

What is the difference between and NFA/Stock and the Extended Stabilizer?

The MCK with an NFA/Stock falls under the NFA classification (see above clarification on explanation of NFA). The MCK Extended Stabilizer keeps the pistol classified as a pistol per the ruling Bureau of Alcohol, Tobacco and Firearms (ATF)

I see the Micro Conversion Kit (MCK) on your website.  What is the difference between the MCK and the Micro Roni®?

We’ve improved our past generation models and created a new generation made 100% Made in the USA -we call it the Micro Conversion Kit, MCK!

Some of the additional advantages of the MCK, include:

  • One model fits more than one handgun
  • Charging handle stays inside of the conversion kit – making it one of the fastest pistol insertions and removal
  • Exposed slide release
  • Ergonomic front handgrip
  • Spare Magazine Holder
  • Comes with Extended Stabilizer Brace
  • Substantially reduced retail price – costing $100 less than the Micro Roni
  • 100% Made in the USA
  • Dramatically improves accuracy up to 200 yards
  • Available in 7 colors: Black, OD Green, Tan, White, Tungsten Gray, Pink, and our USA Patriot Flag

This new Micro Conversion Kit (MCK) is a lightweight, yet sturdy platform, that is currently available in 4 models:

  • Glock 17/19/19x/22/23/31/32/45 (Gen 3, 4, 5)
  • Glock 20/21
  • Sig Sauer 320 (Full Size and Compact)
  • S&W M&P 1.0 and 2.0 (Full Size and Compact)

No, the Micro Conversion Kits (MCK) only fits Generation 3, 4, 5 Glock® pistols. It is not compatible with generation 1 & 2 Glocks.

What Glock® pistols does the MCK / Micro Roni fit?

Does the MCK work with Compensated Glock Models?

With the combination of the Aluminum Top Picatinny Rail on our MCK, compensated Glock Models such as the Glock 17C/19C/21C, and 31C are now compatible inside MCK Conversion Kit.

 

Does the MCK work with firearms that have a manual safety?

Our MCK does not work with handguns that have an external manual safety.

 

Does the MCK work with aftermarket sights on the handgun?

Stock sights always work best, however, the MCK works with aftermarket sights as well, as long as they are not suppressor height sights. Sights should be 0.4 inches or lower.

Troubleshooting

I’m experiencing malfunctions with my firearm inside the unit, what could it be?

If you were to experience problems with malfunctions such as Failure to Eject (Stovepipe), it could be one of a few factors.

  1. Please always ensure that your handgun is seated correctly into the charging handle. There should not be any serrations on the charging handle that are not aligned with the serrations of your firearm. Typically, seating the firearm all the way to the rear serrations of the charging handle will ensure proper fit.
  2. If you’ve done this and are still experiencing problems and have an optic on the MCK, remove the optic to dissect the issue. We have seen ejecting brace hit the base of some optics if the optic is mounted directly over the ejection port. This can be corrected by moving the optic further out on the picatinny rail or closer to the shooter.
  3. Please always ensure that when sliding the firearm into the MCK, the firearm is not pushed forward and locked at an angle. The handgun should stay level and straight as you push it forward to lock on the picatinny rail lock inside the unit.

If none of the above are a solution, please call one of our Sales Reps or Customer service so that they can walk you through a solution via phone and/or email.
