Review: Zius BK1S u0026 BK2S
Not a well structured review video, lol.
tl;dr ver:
bk1s 175fps+
bk2s 155fps+
1s and 2s is exactly the same thing except for the handguard, buttstock and barrel
Proprietary barrel and magazine
T238 Electronic Trigger System
Programmable 2 shot burst
Parts such as the handguard and buttstock are interchangeable
