Hey guys I'm kinda new here , and I recently got the Ares MS338 as well. Shortly after reading this very detailed review, I decided to get the TX system upgrade complete cylinder that was available on Ehobbyasia. So it arrived today , but unfortunately I'm out if town on work so I won't be able to make any tests.
I've taken a couple of photos of the parts in the cylinder. They're all apparently stainless steel and I hope that they can take the abuse. Since this is my first bolt action rifle.. I'm not too familiar with the bits. So here goes.
Notice how it says VSR on the piston
One thing I noticed is that the o-ring on the piston was a bit oversized and wobbly. Is that supposed to be the case?
I'm not sure what spring it comes with but on the ares site it shows that there's either the s170 or s185
Can't really tell coz they look very similar.
I'll try to have a test done at the end of the month when I get back from work.
