ICS M4A1 Piston replacement

[valpas]

Hi, my cansoft ICS M4A1 had recently broken down and made a winding sound when it was shooting. I noticed when I looked into the gun that the piston looked very used and busted.

Pictures of the piston:











Now, presuming that it was my piston that got busted, as it made a winding sound and all the other parts seem to look intact, I was wondering what would be a good purchase for a new piston for my ICS M4A1 Cansoft gun.

For example, would this be a good piston to use and would I be able to use my rifle right away if I just got this:

Alluminum pistons are garbage. Actually I have seen one strip through the course of one day with that exact gun. Get the stormtech.

So will this be the only purchase I will have to make to fix my rifle?

if your getting a new piston that stock piston head is crap too, so u will probably want a new one as well

[valpas]

Could you show me a good affordable piston head as well?

Yeah, had the same problem with my Ics-47 as well, happened in the first week I had it !
Fortunately, my retailer got it repaired !
One advice I could give you for the future, don't press on the forward assist nob, if you could, it releases the spring tension, but could strip the piston !
If you have to open the gearbox, shoot a few times in semi-auto and then, press the forward assist !

How does the Stormtech piston compare to Modify's High Speed Ultra or Quantum piston?

I use the quantums as well i like them, IMO they are a lil stronger, made of a heavier plastic, if you don't mind the extra price buy a quantum, both light weight metal teeth and durable,

I have not used the High speed ultra as of yet, so i can not comment on that one.

Okay I bought the piston head and piston that was recommended to me! I hope this will fix my winding problem and I don't have to return it and can start playing asap!

I have been running an Ultra for over 50 000BBs in an SAW, on 11.1v LiPo... It was still clean, no weak at all.
The stock SRC piston assploded in that same gun (MG36) under 5K rounds.

The winding sound you heard what probably the last metal tooth breaking off and grinding your cylinder. Happened to me true story. I would check your cylinder as well for scoring/damage.

Good to know!
I've run a prometheus piston for 2 solid years and around 200k rounds, still had 75% life, then I scrapped it through user error programming the triggermaster lol
Running a system supercore piston now, it's the exact same style as the prometheus piston, but different type of poly.
Word is they're the shit overseas, we'll see over time, but prometheus is field proven time and time again for me.

I got the piston just today and the gun sounds great and shoots. The only problem is the bb's don't fly as far as they use too and have a unusual FPS pattern, as some go slower then others, is there a reason for this?
