HOW TO SET UP YOUR FX IMPACT M3 FOR BEST MV & ACCURACY.......

To get best MV..... try....
...PROCESS TO FOLLOW...
1. Open all adjustments....
Valve adjuster max...
all the way out ....5+ rings
HS (Hammer Spring) mid ~ #8
Micro to mid ~ #3
2nd reg to 110
1st reg to~170
(All adjustments are at max)

2. Shoot 5 shots to get the MV... let the MV stabilize as the gun settles.
(This will find the starting
2nd reg pressure level.)

3. Increase 2nd regulator until you reach 15-20 fps above your target MV.
...Shoot 5 shots... get MV... adjust...
(This adjustment finds the best amount of air pressure to send the projectile down the barrel.)
The pressure adjustment can be INCREASED without removing the air tank but ...... to decrease the pressure THE AIR TANK MUST BE REMOVED....

The reg. adjustment screw is behind the trigger. Use a 2.5mm Allen wrench with a ball head for adjustments. Adjust the screw
counterclockwise to increase the pressure. Very little rotation is needed to alter the pressure.

4. Adjust the HS (Max wheel) until the MV is a few fps above the desired value......Shoot 5 shots... get MV... adjust...
shoot several shots to allow the gun to "settle in."
*** As the Max wheel is adjusted down the MV will, at some point, drop.
Adjust back to the lowest setting that is above the MV drop. (This adjustment gives the best HS pressure to the projectile.)

5. Now adjust the Micro adjustment until the MV is on the desired value.

...Shoot 5 shots... get MV... adjust...
***Carry out the same procedure as with the Max wheel. (This adjustment gives fine tuning of the HS tension.)

6. Close Valve adjuster (turn it in) until you notice it just starting to shave off the last couple of fps ...
...Shoot 5 shots... get MV... adjust...
***Carry out the same procedure as with the Max wheel. Close the valve adjuster only 1/8 turn at a time.... very precise.
(The valve adjuster regulates the time the air release valve is open. By adjusting it down... turning valve in and finding the MV
decrease.... you adjust the airflow to stop just as the projectile exits the barrel. This ensures the projectile exits the barrel without deviation of flight from too much airflow behind the slug.)

7. Adjust 1st reg pressure to 30 bar above the 2nd reg. pressure. The gun must be degassed to make this adjustment. Take the gas pressure canister off the gun to get to the 1st reg adjustment port. (The ~30 bar pressure gradient
will protect the 2nd reg.)

8. ...Shoot 5 shots... get MV... ensure the MV has remained the same after all adjustments.

WRITE DOWN THE SETTINGS

9. Now the gun can be sighted in!

I wish for your best shooting!

Wow, you really did the group and newbies a solid.

Pretty much how I do it. I just pick a reg pressure I think works for the projectile I’m shooting from research. Set the macro wheel depending on how large of a range I want to go down. Then never touch reg pressure and use only the micro to find max velocity of that reg pressure. If that is suitable I’m done. If not I then adjust reg up or down depending on needs. Do the valve adjuster exactly as you described.

Hello , step 4 ..I dial HS adjuster to a down to a few feet of desired MV but I don’t understand the statement “Adjust back to the lowest setting that is above the MV drop. (This adjustment gives the best HS pressure to the projectile.)” can you clarify?

My valve adjuster only has 4 rings, unless I count the o-ring lol.

There's only 4, but you screw it out till you get the measurement of about 5 or 6 rings.

There are some that come with 6 rings per the FX manual. If you had the 6 ring model then opening to show 6 rings is fully open. If you have the 4 ring model then you open to the 4th ring then another 1.5 turns and that is fully open.

Thanks for the positive feedback.
On thing I forgot to mention.... I measure the Valve with a digital caliper.
I do not use the rings as a measurement tool. The calipers are much more accurate.

I used to do that until I realized 1/4 turn is equal to about .007”. I’ve since marked the top & face of the knob when four lines out with a stripe of white electrical tape and can easily distinguish 1/8 turn. Much faster and no caliper needed. I used four lines as my starting point since one revolution isn’t equal to one line.
