Is I got a m100 lonex Spring off eBay swapped it out with my stock Spring which was shooting 297ish and I guesses the m100 would push it up to 340-340 I don't have a chrono and went to a game today and it came in at 387 do you guys they maybe sent me a m110 Spring by accident or is that the fps a m100 would take it to in a Krytac ?
Krytac m100 chrono 387 fps

Krytac comes with m100 spring, sounds more like a m120.

SHS m100 put my SPR at 335-345.

sounds like a Guarder / Garder spring
these are very often the next rating up or a bit more
the ratings are a guide only - SHS are not bad
but every gun is different so will never get expected 328fps in every gun or every build
usually they get a gun around 330 give or take a bit - could be 310 could be 350
from one gun to another of the exact same model
you got a m120 spring which equates to 393.6 - bit of wear n tear on seals/hop etc....
as Trigger & jcheeseright said
you should get a new shs m100 or look at cutting coils - I don't recommend cutting coils tbh
element do a m105 but this could be a smidge too warm placing you just over 350 in some guns
if you are going to do your own work then at some point you & your friends will need a chrono between you
sounds like a mislabeled spring or a garder spring - they do produce bigger results
think m100 & sp100 do not equate to the same ratings
others like prommy & some others can produce different results
and the 140 or 190% = I haven't got f*cking clue what that crap relates to either
hence shs are a reasonable safer go to bet - but still can produce a bit more/less than expected
soz but new spring or cut it, but needs to be finished off well & still a bit of guess work imho
(I'd get a new spring tbh)

Thanks mate for your info, I've just checked the packaging definitely a m100 but maybe like you said could be labelled wrong,
Don't see the problem with buying things off eBay as long as it's a reliable seller, but thanks for your input it's appreciated

Had you set the hop for the weight of BB you would actually be using? The Krytac hop drops fps as you wind it on, is why I run 0.3g BBs in my PDW as with the hop set it chronos just shy of 350 on 0.2g BBs (it doesn't have any joule creep either so is spot on for where I play) I doubt it would drop 37+ fps though.

They normally chrono about 320ish and as for what spring thats already been answered in your own thread.
It's bad enough you can't google your question yourself but not finding the answer in your own thread is pathetic.
Uk is m100 the only place you get a lower spring is Italy if I remember right, I think they get an m90.

what I meant was does the the gun come with a m90 Spring as stock, sorry that I don't know the ins and outs of these things I must of mistaken this forum for some where to come to ask for advice from others who know, no need for snide comments when asking for advice and yes before you mention it I did try to google the answer but had no luck and no I don't know the fps's to the different springs, but I guess I won't bother asking in the future as I tire of people just generally been un helpfull

It wasn't a snide comment it was a blunt one.
Second post in this thread states what spring is in the krytac so you already had been given the answer. Most people on here are helpful but there is a limit.
Just googled krytac uk spring to see how difficult it was to find the info and got it straight away.
Always happy to help but not to spoon feed.

This thread is a little old but is the top result in google when you search "Krytac M100", so I'm just posting some useful info for others who land here.
My CRB chrono'd at about 290-300fps on the stock spring, which is around normal for a UK spec MK2 CRB. I tried an SHS M100 and a Nuprol M100 and with hop set to OFF both were 375fps or more (the SHS one was more like 385fps actually).
On the Nuprol M100, with the hop set correctly for 0.28s, which I tend to use, it's pretty much bang on 350fps on 0.2s (my chrono was reading 345-347fps on average). The 0.28s are at around 295fps, which is equivalent to 1.13 joules, so perfect (my local sites tend to have a 350fps limit on 0.2s, which is also 1.13 joules).
I'd pretty confidently say that the stock spring in a UK CRB is most definitely NOT M100, it's more like M90. There is a noticeable difference in the stiffness of the two M100s I bought in comparison to the stock spring - the stock spring is more easily compressed in the hand.
So, NathyB, hope you find this useful. The answer is that what you're seeing seems to be normal. Stick with the M100 and tune your hop for a heavier weight BB, which is something I would recommend anyway for outdoor play. You should find that on 0.2s, your velocity drops back down to around 350fps. If it's still a little hot, give the Nuprol M100 a try, it was about 10fps lower than the SHS one for me in the CRB.
Cheers

Read this

The guy answering called Allizard is one of the Kriss USA managers and deals with the UK side of things so pretty sure he knows what he is talking about.
Also you cant tell what rate a spring is by compressing it in your hand.

Yeah I've seen his posts on that forum before and he clearly knows what he's talking about.
I'd guess perhaps myself and OP received our CRBs from a batch that for whatever reason (part availability, or perhaps originally intended for Italy?) weren't shipped from the factory with an M100 equivalent spring. It's worth noting that he doesn't categorically state that it's an M100 in all UK CRBs, he leaves some ambiguity there.
Otherwise, why would I see such an obvious difference when replacing the stock spring with two different M100 rated springs? I mean, I literally swapped the springs and tested them myself.

I have worked on fair few and never seen those results on an m100. The first one was mine which was imported from the states and fired 335 and dropped to 320ish after about a 1000rnds after I changed the spring down to an m100.
Sure, I thought it was a bit odd myself to be honest, hence me buying the additional M100 and testing again, with a very similar result.
My results are what they are though. Two different brand M100s = 375+ fps on my otherwise stock MK2 CRB.
I'll monitor the chrono readings I get with it as time goes on - maybe hopup rubber wear, cylinder / piston wear and maybe spring wear will change things. In that thread you linked, Allizard does say at one point "pretty sure you have the type 1 cylinder" - this could indicate that there are slightly different combinations of components in certain batches, so who knows.
Real world results will always trump what some dude on the internet says in any case

Wish I'd known that sooner, I've an 85, 90 and 100 and non of them give me 1J.
I cut several coils off the Guarder SP100 and still chronoed 365 last time I was at the mall due to the rings on the reinforced spring guide, and 335 with the normal guide.

m85 Guarder "should be near it" but all fps/muzzle energy/joules stuff varies in each gun...
But Guarder's are usually said to be a Guarder SP100 = M110
or the next one up
or they make/chrono/rate their springs for 0.25's
But basically Guarder springs are a not same as M??? springs

That guy told me (roughly, I don't have the exact quote to hand) "it's incredibly rare for the gears to fail before anything else on a stock CRB or SPR", the gears in my CRB and my mate's SPR both (for want of a better phrase) ate themselves within 4 skirmishes (we bought them from landwarrior, 1 week apart). granted we could have got a dodgy batch, but it goes to show that even the "experts" don't know everything...
All that aside, useful thread.
It is incredibly rare to be fair to Krytac. The gears on a krytac are much stronger and have a higher rockwell rating than SHS, ZCI and a BUNCH of other gears on the market which you should expect from the price of the gears. What battery were you using? The piston should of eaten itself first definitely way before the gears would of even showed signs of wear so the motor height may have been way too high which I found out I had when I first took it apart to inspect height and that. Also, the shimming may have been way off which is again very rare and I had some fairly tight shimming but it wasn't that bad and then obviously the clear choice here which is you probably got some f*cked batch which I know that guys from Matt the Musketeer's team had.
