Clips can now be widely bought around town! 30 Pack Streamline darts are coming too.
I calculated, 30 dart packs costs RM29.90 (Round off to RM30.00)
4 packs costs RM120 = 120 darts.
The ammo box RM120 (RM119.90) and you get 100 darts + A box lol. Personally I think the box is better if I were to buy.
ckneow: Nerf's community is not really wide in Malaysia, the likeliness of any place renting Nerf's like paintball is really really low.

I doubt anyone will let you try theirs also lol

You can get a really good one at RM34.90, the Maverick.
To answer the post about the Redshift CS-12: I don't think there will be a NERF 'Sniper Rifle' soon, since darts can't really fly far unless it has some very powerful force or something (which will be expensive I guess?) and zoom scopes are pricey.
If you're interested though, the Raider CS-35/6 is coming soon and its from the game with some minor difference such as the front grip.
There's rumours about the Nerf Spartan CS-12 coming though... Not sure about that.
