Yeah I know.
But still pisses me off..
Btw the arp spring guide has a spacer, not a proper thrust bearing but does the same thing.
Oh well at least I got to clean up the mess created by the plastic king arms piston I previously had in the gun.
There is an air leak around the nozzle, but I'll wait to rebuild the whole box to fix it.
Beat me to it, was going to suggest of course obligatory broken spring replacement but whack an 0-ring nozzle in there whilst you're at it.
On my Ares 008 I'm using an M90 with spring and pistonhead bearings with a 128mm 6.01 inner and it sits just about on 1J, really shouldn't need an M110 to get you there.
5mm & 10mm thickness
Alas the 5mm thick has only a M5 hole
so you may need to widen it a bit depending on piston head fitment
a 3mm tooth equates ROUGHLY to M05 or 16.4fps
so ROUGHLY a 5mm spacer adds up to 27 fps
& ROUGHLY a 10mm spacer adds up to 54 fps
Or a 5mm spacer will offset most of power lost from SS 2 teeth
& a 10mm spacer will offset a smidge more than SS 3 teeth
APROX - it kinda works but airsoft physics never works out
exactly in every case - but along those lines somewhat
One word of caution though...
If using a 10mm spacer, double check some longer spring guides
do not bottom out on spacer at full 101% stroke
it is very rare but one spring guide just kissed the 10mm spacer
at full retraction
Not really an issue for me as I SS quite a few boxes
but on say a full length AK 455mm where you keep full or most of stroke, then it is something to remember if trying to boost power
(either a m80 spring to get 350fps or a m100 spring for DMR use)
Then if boosting the spring compression/power with a 10mm spacer
just see if the guide/spacer come close to bottoming out...
FUCK IT - pics say a 1,000 words...
variation in spring guide lengths:
(no they are spring guides not collection of "other toys")
and some instances where a longer spring guide might bottom out
Now admit that is due to the collar from bearings being used...
but you get the idea of what to watch out for
(and why you should not push it with longer 15mm or 20mm long spacers inside piston)
So I use 5mm or 10mm thick 15mm spacers
and wtf as i revisited my old imgur account
here is 007's view on which gears to use...
