MCK - FAQ
Everything You Wanted to Know About the MCK – Answered
Have you been considering the CAA Micro Conversion Kit (MCK)? We’ve gathered and answered the most common questions to help you make an informed purchase and understand the key features across all MCK generations.
1. Can I run a ported barrel or slide with the MCK?
Answer: No. Ported or compensated barrels and slides are not compatible with any MCK generation. These barrels release gas upwards, which may interfere with the internal structure of the MCK and cause malfunctions or damage. Use only standard, non-ported barrels.
2. Can I use a suppressor with the MCK?
Answer: Yes – but only with Gen 2 and Gen 3 models.
- MCK Gen 1: ❌ Not compatible with suppressors
- MCK Gen 2: ✅ Accepts suppressors up to 1.38” diameter
- MCK Gen 3: ✅ Accepts suppressors up to 1.50” diameter
Both Gen 2 and Gen 3 also support suppressor-height sights. Gen 1 does not.
3. What’s the difference between MCK Gen 1, Gen 2, and Gen 3?
Answer:

Answer: Only MCK Gen 3 supports pistols with slide-mounted optics (e.g., red dot sights). Gen 1 and Gen 2 do not.
