I currently have this in my Kronos with a k25 spring and it helps the prime a lot. I went from one round every two seconds with top prime and now I can do about two rounds every second.
It is a must have if you upgraded your spring... even K25 is better to have this.... the T pull itself will fit white Kronos with just abit cutting.... but I found out it doesn’t fit Blue newer Kronos.... blue Kronos has a tighter gap at the back..... white Kronos will be fine fyi! Overall fast shipping and good quality
If you plan to add a beefy spring to the Kronos, this is such a nice addition to have. I don't have the arm strength to prime an upgraded Kronos reliably, and this makes priming much easier, a little harder than priming the stock version in my opinion.
You do need to cut the Kronos' shell a bit to fit the handle in, but it's not too big of a deal. Also the price is quite high, though I am glad they made this part with metal rather than some sort of plastic.
Overall really happy with the priming handle to make the Kronos a fun handcannon to use.
As the title above says I would not add a heavy spring to a kronos without this. The leverage this provides makes pulling the 18kg spring upgrade almost easy.
Once installed, it helped lower the toughness to prime, and I was finally able to install K26 and prime the blaster. Wonderful, just a bit pricy.
