SDIK Mancraft bluiding presure in steps.

Hello dear airsofters.

i got a problem with my HPA/Co2 SDIK from mancraft.
If i pull the bolt backwards you can hear that the regulator ia building presure with steps you hear clearly tick.. tick... tick... and i did ask other mancraft owners and the dont have that. so i maild mancraft with the question how to fix this. and the did send me some o rings but that did not clear the problem. so my question is are there other people with the same problem? and if so did you clear the problem?

kind regards

Sjors. a.k.a Lonewalker

There are numerous reasons for this to happen. For starters what regulator are you running?

That is partly the problem. The mancraft regs are not all that good. Now when you say it jumps in steps, you are referring to the gauge correct?

If so, then there are a few possibilities. Lack of lubrication, over sized seals, dirt, over tightened fittings, thread locking compound migration. Most of those were a problem on the one I have, except the dirt.

If not, look for kinked lines and clogged ports.

yeah i need to wait around 5 to 10 seconds for my next shot other wise it will not be 470~fps but it will be around 300~fps. if i wait longer then 10 seconds then i got my fps around 470. its a total new kit. never has seen the battleground. and all seals are lubricated there is no dirt and stuff. and the other stuff i dont realy know because i have never disambled it.. except for seal replacement.

what will me a good comparison for an other regulator in the EU?

In the EU, no clue. I do not live in the EU or shop in it, so I would not know what is available.

I binned 2 mancraft regulators for the same reasons. I think they are a bit hit and miss. I couldn't find a 3rd party regulator for co2 so went HPA

Palmers makes great regs for co2, however you guys in the EU get the shaft for those.

Regulator ~$100 (https://co2reg.com/collections/airso...r-low-pressure)
Quick change ~$35 (https://co2reg.com/products/cci-12-g...change-adapter)

Shipping + VAT + Misc parts you may need. Adds up really quick.

Yeah I should really say I couldn't find a decent co2 reg in the uk. The only option was ordering from the USA which is never a good idea especially with the exchange rate right now.

If you only have the problem, when the you pull the bolt, that would be a leak in the cylinder assembly.
The regulator should be somewhat fine, as it only reacts to the pressure falling in the cylinder.
But I would think the regulator should be falling more evenly, and not in ticks.

That said, the main problem would be the cylinder assembly.

A leak could be anything from a damaged needle?(That thing in the middle of the piston), to a damaged o-rings, like the ones that connect to the needle, or the ones the seal the piston.

After about 400 test shots, I've noticed the same issue. Also I've noticed a fps variation of 50 to 60 fps.
Next month I'm gonna buy a storm regulator. Hopefully this will work better.

Should work, I have heard nice things about them. Have not used one yet.

I still prefer multi-reg solutions when playing with CO2. But you should be ok with a single.
