Mostly its just the look, but some claims in prior nstrike elite blasters (yellow colored), special editions such as clear series (transparent white) or sonic series (transparent green) performs better in range compared to original ones (such as longshot cs-6) because of slight upgraded internal parts.

Most of the time need to buy the blasters then u have extra part (like bipod fr stampede, firefly tech mag from rayven, n etc.) But sometimes if u r lucky u might find mission kit which bundled the parts together (like element blaster mission kit which comes with scope and dot sight, or dot sight with 5 darts, n etc.). Or buy second hand in ebay just fyi toys r us give free pin point sight for purchase of nerf blaster more than RM80 before christmas last year, and that pin point sight is the most rarest most wanted acc nowadays

Didnt know that there are nerf players/collectors and nerf forums in Malaysia, and hello, I'm new in this forum, nice to meet you all
