This item is older. There has been much time to improve this with hands that match the color of the Mp10 as well as hands that hold the gun better. They should not be charging $20 for something that doesn’t work. However the style of the gun and the fact that the older hands can hold it Is why I still gave two stars on this review.

Purchased this for my KO MP-10, because I have the KO of Prime there were a few issues putting the hands on due to slight differences in official figures and KO's. The only real complaint I have is that the thumb on the left hand was loose, not a huge problem if you have nail polish or clearcoat.

TFSource delivered as always.

However, the product isn't as I hoped. First, the cannon does not properly peg into the hand. Second, the redesign of these hands was not an improvement. Now, when the screws are removed to position the hands, the little fingers go everywhere.

*** I would not recommend this product if you have a KO. You'll have to do a lot of altering to get the hands to fit.

It doesn't quit fit in Prime's hand. I popped the thumb off more than once trying to place it...

Easy install. Just be careful and mindful when pulling the new hand apart so the fingers don't fall apart. The fit is really tight on the MP-10. Almost too tight. I hope it won't strain the plastic peg it connects to. The gun doesn't fit perfectly, so you might have to do a tiny touch of sanding. Other than that, great to have.

Somewhat easy to install (intuitively), though no instructions or screwdriver like Fanstyle's upgrade to MP-18
One can transform MP-10 easily but you have to turn hands in a special position so you can do it.
Short thumbs, odd articulation of base of thumbs... but I can live with that.
The rifle is just awesome. Fits into new hand nicely and gives MP-10 more personality.
