FX FX impact M4 velocity “warm up”

does the valve rod came straight out after removing the C1? or do you have to take apart the plenum?
Take it apart to the point that you can remove c1. Then pull the rod out towards muzzle as far as it lets you (otherwise you can damage it when unscrewing plenum). Then simply unscrew the plenum (with the power block etc still on it. Then pull the rod out towards the back end through the front piece of the plenum).

Thanks for the tips, will do.

How often do you plan on yanking out the valve rod for cleaning/polishing? 1000~2000rd to keep it as clean and as consistent as possible?

Well, I hope that polishing it plus getting some more shots through it will eventually get it to a point that there’s no more wear on the orings guiding it… for now I guess I’ll do it whenever I notice that I need more than 5ish shots or get back to tuned speed or whenever I have the gun opened up for whatever reason.

I didn’t grease/lube it since lube will eventually wear off and provide for its own source of inconsistency but if it gets bad within a 1000 shots or so again I might as well do that in addition.
 
This was exactly my beef with the M3. I had to buy a HUMA regulator to mitigate this. I can't understand why FX does not fix this. I guess I can understand it. Because we keep buying it. Why was my Uragan 2 never off speed even after sitting for 2-3 months?

But at the same time I just love the versatility and the accuracy of the M3. I was going to consider an M4 if this was no longer an issue. So I come here to search for this and there are several threads. Well... scratch that! It seams it actually got worse rather than fixed. I probably should just keep my M3. Sorry guys! I was ranting.

You got lucky if a reg fixed the issue. Most have nothing to do with the regs at all but the design of the gun itself, having a 15 mile long valve rod. It’s like me, needs several kicks in the butt to get moving after it has sat around for awhile. Lol
Also the 200 page old thread on this issue has been revived. Someone on that thread is saying FX has redesigned the valve to fix this issue and it will be available soon.

i may have posted on the wrong thread but anyhow a member on this site has 2 new o rings for the plenum non silicone rubber
he also has a new plenum design that are made on a 5 axis cnc machine. also has valve rods that were carbide coated and polished on a diamond wheel.
i drove down to mass to meet the guy x drag racer/ Mit engineer
he said all this started with a Notos several months ago i purchased the o rings for both my impacts m3 m4
i also gave him a deposit on the valve rod and plenum which his m4 has all 3 in it he went and grabbed it and said watch it's been here all morning.
1st to last shot 990-993 3 fps that was impressive.
i did what he said installed the new o rings with just a dab of super lube grease like he said m3 1st shot 890 2nd on 900 901 902 901 right where it should be
whatever he made that o ring from just works some of you should try them you may just like your guns again
can't wait to take the m4 apart that's all for now,
