Disappointing overall, the larger of the 2 hammer springs becomes lodged in the channel way. Depinger works ok. don't need the extra space in the mags. Nor the bottle adapter. I find it's a waste of money.
while you do have a point, there is considerable difference in .177 and .30 cal. my friend has a .22 version and there was definately less ping. But, as I stated, the depinger worked, 1 of the springs work. just don't need all the other stuff, especially for over $100. Better if it was just a spring and depinger either together or separate, for 35-40 bucks.I have procured a few springs that are more beefy, got them from a local spring company, not hammer though as its just the .177 i have.
I dont feel the vulcan 3 have much ping, but there are some rattle in the mechanism, something Ernest also address in one of his older videos on a vulcan 2 as i recall.
It is my feeling that many upgrade kits for airguns, depending on what you do / want to do, not really needed
