I own a stock FX Impact Mk1. I went to the Huma Air website, and I found all the accessories that I need for my project, from a Power kit that I need to upgrade my MK1 to a Hybrid M3 that’s how it is named now. I saw all the upgrades for the conversion, such as High Flow V2 Dual Hole Transfer Port For FX Impact, FX Impact M3 Ambidextrous Side Lever Kit (FX20602), Power Block Kit FX Impact MKI & MKII FX20839, High Flow Slug- and Pellet Probe For FX Impact, plus Huma-Air XL Magazine For FX Impact – .22 / 5,5 × 2 and you are gonna need this too: FX Impact Side Shot High Capacity Magazine Conversion Kit. or use your old magazines if you prefer they still fit right but less shot capacity.
Now, it has more power. I assemble the new parts by myself, and it works great! Note: Once you add the new power block kit, your MK1 original barrels will not fit properly, but that’s fine because I updated everything that was on my list, too. I want to have the new M3 barrels to make it worth it. The M3 barrels fit perfectly due to the new power block, and once you start shooting, you will feel the power of the MK1 as a completely new FX Impact. I was amazed with a WoW! Tip: Once the Impact MK1 is disassembled, do an internal cleaning for better functionality with the new parts. Remember, from now on, use the M3 Barrels and any other accessory that you may need to have your new Impacdt MK1/M3. If you have any doubts, contact Huma-Air, and they will answer your questions. Once you have completed your MK1 upgrading project, You will be a Happy Owner. Thank you to the Huma Air Team for answering questions and fast shipping! Bravo Zulu to Huma Air!

Huma, what a great company.
They have literally everything that I need to bring my rifle to the next level.
They make my buying experience very easy and they have good knowledge of their products.
I will continue to buy my products from them.
Great service and great products.

Efficace, pour exemple, m’a permis de baisser la pression de mon ImpactMK2 .25 Power Plenum de 10Bars pour des performances similaires.
NB: l’augmentation de puissance est plus importante avec le canon de 600mm qu’avec le canon de 700mm..

About the powerblock i must say that it works great combined with the tungsten hammer, hammer valve spring…
I now push 32 grainers up to 325m/s with the 700mm .22 sniper.
Thanks huma.
