Will m3 short lever arm fit for mk1/mk2?

Ok I'm confused now. Just got words back from fx usa the cocking short lever does not fit older impact. So just letting yall know it doesnt fit on older model.

What is so appealing about a shorter cocking arm? I would think longer would have better leverage (MKII), at least that's been the rule since the beginning of time. A little confused on this one.

If you have an impact you should try one. There is almost imperceivable extra cocking effort, but you can reach the lever without moving your had from or at least forward on the grip. It greatly reduces time between shots for followup. It doesn't seam like it should make a big difference, but it definitely does. I had the short throw arm on my MkII so it was a nice treat that it comes stock now on the M3. It would be hard going back now.

If you have a really good shooting MkII I don't know that I would upgrade. This one is easier to tune for sure, and seems to have a little more power from the factory, but if your MkII is already tuned then that is not quite as appealing. If you like to switch calibers often, then it is definitely worth the upgrade.

I can see that with having the new toolless hammer adjustment, and with having more PW notches to work with. Something I'll be adding to my wheel via a drill bit. I do have a .25 and a .30 cal setup for mine. Hey, tuning is half the fun sometimes. I can, without hesitation, say I love the FX Kool-Aid I've drank. I popped 15 tree rats in the head at a fix 85 yards a while back, and am still pumped and shocked that I was able to do that with the .30 cal setup at 89 FPE. So, no hurry to replace my FX currently. I am still keeping up with the latest innovations and offerings from FX and don't want to fall too far behind those, but for now I am good to go.
