TOKYO MARUI 89 type ORGA Heavy Recoil Bolt Shaft

We have created this part to boost the recoil on the 89 type GBB.
The bolt shaft attached to the bolt carrier is made of brass.

A genuine bolt shaft for Tokyo Marui 89type GBB is made of aluminum and weighs about 30g.
On the other hand, ORGA's product is 94g and works well even when 134a gas is in operation. Compared to a genuine Tokyo Marui product, the weight is tripled. This is recommended for players who want to make the 89 type GBB into a heavy recoil.
AS you can see in the video below, it works operates perfectly with a 134a gas.
