Product Description
Guns Modify SAI type Speed ZERO bolt carrier GOLD for Tokyo Marui M4 GBB
-Made by Guns Modify
A SAI type aluminum bolt carrier compatible with Tokyo Marui's M4 GBB.
Guns Modify's unique ZERO Resistance design greatly reduces the resistance during blowback, enabling smooth operation and speeding up of the bolt carrier.
Bolt B (genuine model number: MGG2-133) is different from a genuine product made of aluminum, and adopts steel made of high strength with bolt extension and weight locker.
The recoil feeling can be adjusted because the weight can be changed according to your preference.
The material of the bolt carrier is 6061 aluminum alloy with excellent rigidity and light weight, and it is machined by a CNC process under computer control, resulting in a very high work accuracy.
For advanced users, this product requires air gun disassembly and assembly technology.
We recommend fixing the weight locker with a screw lock.
