Micro Roni Stab X (Gen 4) CAA Gearup PDW Converter for S&W M&P9 2.0 / M&P9 2.0 Compact / M&P40 2.0 / M&P40 2.0 Compact


The same, great conversion kit will be released for the S&W M&P9/40 2.0 in the next few months!

SKU: MIC-RONI-STB-G4-M&P2.0 Category:


Out of stock


Warning!!! Lately, a conversion kit that looks like the Micro Roni has surfaced in the US under the name "MCK"; The MCK is unsafe and dangerous to use, it doesn't include a trigger guard (which already caused an unintended discharge last week) and is not related to CAA at all!

I'm repeating,

MCK is not a CAA product!, whoever sells it uses their good name to attract sales which is a clear violation of CAA trademark.

Read the following letter to from Moshe Oz, Founder & President of CAA Industries Ltd. that proves the statements above:

Letter from Moshe Oz

This version doesn't require an SBR Tax Stamp!

This new, improved version of the Micro Roni will feature two slots for drop-ins one for the Micro Roni flashlight (MRFL) and an additional one for the Micro Roni Laser (MRL)

The Micro Roni Stab for S&W M&P Conversion Kit is a great option to use if you want to be better with your self-defense skills, it can be used in various positions and in a perfectly convenient way!

If you are looking to upgrade your Glock to be more than just a pistol, the micro Roni stab is the perfect fit, it is fast transforming and it gives a lot of advantages that are described below!

With the S&W Carbine Conversion Kit, you can use your pistol and feel like you are holding a rifle with benefits.

Here is the description of all of the features and a warranty that comes with it:

  • Brace is firmly fastened on user’s forearm with an adjustable nylon strap.

  • Ambidextrous, easy and fast cocking handle.
  • Ambidextrous trigger-guard safety.

New, Micro Roni X Stab Gen 4 Features:

Micro Roni Gen 4 Features

  • All Gen 3 Features.
  • Captive Charging Handle - In the other versions, the charging handle could be pulled out with the gun. CAA has received many complains about it and decided to upgrade the kit so the charging handle is locked inside. The charging handle won't fall again.
  • Larger and flared ejection port - allows better ejection, especially of weaker ammunition.
  • Open hatch with access to the pistol's slide-stop. 
  • New triangular-shaped barrel shroud - Allows the mounting of CAA "Plus" muzzle accessories: MR-CMP (compensator) and PMD (serves as a flash suppressor, a close-combat tool, and a standard window-breaker).
  • An extended brace which allows a better holding of the Micro Roni. This too, was changed due to many customer requests.
  • Interchangeable front grip which allows you to hold an angled grip (stab version) or mag holder (regular version). CAA may add additional accessories that will connect to the button rail and provide you with additional functionality.

Available in three colors: Black, OD Green & Desert Tan.
