Most Helpful Positive Review Mck thumb rest
On first arrival of my mck conversion kit I was impressed how the front grip was so thought through. So thought through that they sold you back the thumb rests as an option. To me I feel as though the thumb rests are a must for the mck. Unfortunate they’re a separate item that has to be purchased se...

Most Helpful Negative Review Ok for the price
So these do what they are supposed to do however they should probably be 1/2 the price for what you get. Nothing here costs anything and it is just another way for this company to make some extra money. But hey it does what it should.

yeah theyre nice

by Rod, Verified Owner from MO, United States Written on July 8, 2021
20 dollars for two small pieces of plastic. So is it worth it. Obviously not it two small pieces of plastic don’t be an idiot. However does it make the kit feel better? Yes. Are you gonna put anything else on both of the side rails? Probably not. Does it make the kit look better? Yeah. Is there another option? No. You’re already in too deep.
Pros:
  • feel
Cons:
  • my pride
Best Used for:
  • i would assume putting them on the side of a MCK
Would recommend: Yes

Perfect item

by nasty Nate, Verified Owner from CA, United States Written on July 2, 2021
Works good on your roni as well as your AR. I have them on both all my setups and it’s perfect no complaints this far. Item slips right on and locks in place for a nice secure fit. It’s easily removable as well.

Easy to install

by Ed, from PA, United States Written on April 6, 2021
For such a small piece of plastic, you wouldnt think it makes much of a difference, but it does!

Its easy to install. You get ambidextrous grips. They really help to get a good grip.

Putting them on and taking them off, requires you to pull up a little bit on the end bit, that hooks the rail system.
Would recommend: Yes

A must have

by Steven, from TX, United States Written on March 22, 2021
I recommend these for safe finger and thumb placement when shooting the CAA MCK. The short barrel requires proper grip of the weapon for safety. These are perfect, comfortable and stylish. The fact that they are for both right and left hand shooters are cool but not required to use both.
Pros:
  • A must for the MCK
Cons:
  • None
Best Used for:
  • control and safety
Would recommend: Yes

Excellent thumb rest for PCC or AR pistol

by CZ-Reptar, from GA, United States Written on September 22, 2020
I purchased this thumb rest for my CZ Scorpion to pair with my Magpul AFG 2. It allows me to have the same grip strength as the C clamp style grip on my handguard without having to go over the top of the handguard with my thumb. It looks amazing and functions even better. Easy to install with a clean minimalistic look.
Pros:
  • compact
  • Affordable
  • EASY INSTALL
  • clean look
  • great texture
Cons:
  • None
Would recommend: Yes

Added safety

by STLGLOCKFAN, Verified Owner from MO, United States Written on August 6, 2020
The thumb rests mount on the existing side rails and, while a little high for my smaller hands, they add a level of safety needed to prevent a hand moving forward during firing. You get one for each side. Feel solid.
Would recommend: Yes

Great accessory

by Carl, from MD, United States Written on June 11, 2020
The CAA MCK Thumb rest was an excellent addition to my pdw. The thumb rest was just what I needed to to get my hands in perfect position. The product fits the needs of both left hand or right handed shooters.
I would highly recommend this product.

Must have accessory

by Francis, from VA, United States Written on March 31, 2020
This thumbrest is a must have accessory. Price is good. Thumbrests are very durable and mount up easily on the side rails. When you put your hand on the front grip, its a natural place for your thumb to rest on and keep the muzzle flip down.
Would recommend: Yes
