Micro Roni Gen 4 (G4) CAA Gearup PDW Converter for S&W M&P9 / M&P9 Compact / M&P40 / M&P40 Compact


The same, great conversion kit will be released for the S&W M&P9 and M&P40 regular and compact versions in the next few months!

SKU: MIC-RONI-G4-M&P9 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:
