I totally tuned my fx impact. It was mk1 but I put a mk2 valve and 25% extra plenum fac sprin plus many more tweeks and drilling’s I set my huma reg onto 90bar it is now at 65ft lb and firing 1072fps. I altered the forward control knob and brought FPS down to 944 to tighten groupings very quiet...

I did put the fac hammer spring in which is slightly thicker but shorter than the UK version and it did make a real difference however I am certain you guys are right about the hammer itself. It all makes sense to put a heavier one in I’ve ordered an fac one so il weight it more with lead and...

That’s very interesting Keith, I really appreciate that where can I watch “our gear part 1” ?

61 ft lbs is a monster power what is your FPS on that

Perhaps change light hammer for heavier hammer and change regulator this may be enough. I drilled barrel to 8mm and the front wheel port hole to 7mm so a massive flow but is there anything else that needs to be drilled I have missed? 

That’s an interesting thought. Where is the valve seat? Does the regulator port hole need to be bigger

Just found online the fac hammer and bought it. I already have the fac valve spring so that should compensate and with a little luck it may add a few more FPS. Thanks for all your help guys 

Thanks for that information jcd it’s very helpful i understand that it’s not .30 so 70ft lbs and 1000fps is probably not achievable but at leat hi 700’s to bottom 800 FPS would be nice

I just tightened the hammer spring then adjust the reg pressure. I do notice though as I shoot a few magazines and bottle pressure drops. So does reg pressure 

Thanks for the information regarding the hammer. It is a fair point I did look around to see if there was a heavier hammer but couldn’t see one. Maybe it’s a special order. Il have to re look the reg pressure idea is a fair one too I did think tonight maybe I should try dropping the pressure a...

It would be illegal if I didn’t have an fac licence lol I could have bought an fac version but thought it would be more fun and rewarding actually working on it myself 

Hi guys. I have a UK restricted crown. I have changed the 22 barrel for .25. And main spring for fac. Changed valve spring for fac international version Cranked up regulator to 150 bar. Tightened spring tensioning screw to full and have power wheel on max the front wheel that turns from 177...
