The MCK for 1st generation M&Ps uses the same body and charging handle as the M&P 2.0 MCK. Because of this, your MCK for a first generation MCK will still say “2.0” on the inside of the ejection port and on the charging handle. This is normal and your 1st generation M&P will still fit inside the unit securely as expected. Click here for more info

This Micro Conversion Kit is a lightweight and sturdy platform for Smith & Wesson handguns. It has a barrel shroud made of aluminum with a polymer body. The extended stabilizer, which now comes standard, enables one-handed firing for better shooting performance. It also comes with a Velcro® strap fastener which provides a custom fit to any user. MCK is the most cost effect conversion kit in the world. Fastest assembly/disassembly conversion kit on the market. Improving accuracy dramatically up to 200 yards. We are the exclusive licensee of the SB tactical stabilizer brace for the handgun conversion kits

If you have a manual safety lever on your M&P, you will need to remove it to use in your MCK

    The hype is real. Delivery time was fast. Easy to load my handgun into. I like the ambidextrous parts of the charging handle and flashlight. Flash light battery goes out quick so I just replaced it with a better one. The whole design is complete and makes you feel like you have a short barrel rifle. Can’t range to test it at the range

    The MCK delivered fast. Fit is perfect and looks great. Size is very comfortable and stable to fire. This platform really improved accuracy of my 40 cal at longer range, 70 to 100 yards it truly is unbelievable. Top rail fit my Eotech setup just fine. Brings a new level of enjoyment to firing my M&P 40. Great buy and great service.
