The CAA MCK (micro conversion kit) makes some big promises, but to know if one of these platforms can deliver, we need to answer some questions about them. Here are some of the most common questions, answered.
- Will an MCK reduce recoil?
A CAA MCK, or micro conversion kit, will actually reduce recoil and in a big way. For one, it will increase static mass, which will considerably increase recoil absorption. That alone reduces recoil.
But, more importantly, a micro conversion kit enables the operator to shoulder the arm, which in turn will enable the operator to redirect the force of recoil into their shoulder rather than having to absorb it while shooting a handgun with a standard grip.
- Will an MCK improve accuracy?
An MCK will not make the gun itself shoot more accurately, but since it will give you the flexibility to shoulder the platform, it will likely improve your ability to shoot more accurately. Most users report that their accuracy improves significantly with an MCK, even at intermediate ranges around 100 yards. Also, the ability to mount an optic like a red dot sight (or scope) can influence your ability to shoot accurately at greater ranges.
- Can I add attachments to an MCK?
Yes, one of the biggest selling points of a micro conversion kit is that it will offer a number of mounting points for shooting attachments like red dot sights, sling mounts, and much more.
Micro conversion kits also can be expanded with rail adapters that offer more mounting points for shooting attachments, so even if you don’t like the space a standard MCK offers you, you can expand on it.
In addition, there are a number of purpose-designed MCK accessories that are specific to micro conversion kits, like flamethrowers, flashlights, thumb rests, extended charging handles, stocks, bipods, and much more.
This is one of the strongest selling points of micro conversion kits, as they offer considerable space for expanding the platform with utilitarian shooting attachments and other MCK accessories.
- What modifications to the gun does it require?
One of the greatest things about CAA MCK platforms is that they don’t require any modifications to the guns with which they are compatible. You can basically take the handgun, open the door at the base of the MCK, slide the gun into it until it locks, close the door, and get to shooting.
Unlike other conversion kits which may require extensive modifications to your handgun, micro conversion kits are much simpler, straightforward, and shooter-friendly to use.
- Are ported barrels and slides compatible with an MCK?
Ported barrels, or ported barrel and slide systems cannot be used with micro conversion kits. This is because ported barrels vent gas upwards, which will be trapped inside the chassis. This can interfere with the operation of the platform, damage the MCK, or cause dangerous conditions for the operator. It would also deposit an excessive amount of fouling inside of the MCK even if it did not damage it. No MCK generation is compatible with ported barrels or ported barrels and slides.
- Will my zero shift if I remove the gun?
One thing to note with micro conversion kits is that, even though they are easy to configure and require no modifications to the handgun, if you remove and then reinstall the gun, you should expect your zero to shift.
Therefore, if you remove and replace your handgun in an MCK, you will need to recalibrate your sights, whether you are running iron sights or an optic.
- Can I run a suppressor with an MCK?
Suppressors are not compatible with generation 1 micro conversion kits. Generators 2 and 3 micro conversion kits actually are compatible with suppressors as they offer the necessary internal clearances to accommodate suppressors. Check your owner’s manual before installing one, though, as they can only accommodate suppressors of certain sizes. Also, you can run suppressor height sights with them, but again, only with generation 2 and 3 MCK platforms.
- How do I maintain an MCK?
Maintaining an MCK is easy enough. Clear and remove the handgun from the MCK and clean the interior and exterior to remove fouling deposits. The main area of concern is the muzzle shroud, and the area around the muzzle and the ejection port. These areas will accumulate fouling at a higher rate than the rest of the platform. Otherwise, just make sure the rest of the MCK is relatively clean and free of fouling, oil and other deposits and you’ll be mostly good.
