Sniping - Tight bores and buckings...
 

I'm about to place my order from shop.ehobbyasia.com (can anyone confirm if this place is reliable?) but before I check out I would like to make sure I'm not purchasing something that won't be compatible.

Echo1 ER25K (400-410 fps with .20g BB's)

The barrel I am looking at

Are tight bores universal to all hop ups? And are buckings universal to all tight bores?

Firefly bucking, however, I am not sure if I should go for hard or soft due to my fps...

I'm not sure if you are trying to import or not....but if you are, see "First", if not, skip to "Second"

First of all....you can't really import any guns from outside of country (not going to go into that too much), but essentially, you need to factory or expert prove that it does fire above 366 fps.

Second, ehobbyasia is quite reliable as far as I can tell.

I already have my rifle, and as for the importation, I paid for the import document of which the gun's fps was tested, and it clocked in between 400-410 fps. Though this doesn't answer my questions ;P

Yes
Yes
Soft.

Try shopping for those parts locally. You could possibly save yourself some money, and a lot of time.

The only local store is Airsoft Quebec, which I doubt hold either of these parts. Both are high quality parts, and it's already hard enough to find firefly buckings anywhere outside Asia. How much more expensive are we talking about? I know it take about 20 business days to receive the order though...

I don't recommend trying to import the gun, but if you are looking for upgrades, there are places in the States well suited to that, though some are better suited for Canadian orders (namely Trinity Airsoft and Eastcoast Airsoft); I've found that Eastcoast Airsoft also has a nice selection of hop up rubbers and inner barrels
