Bolt forwards Assists

The bolt foward assist in airsoft serves exclusively as an aesthetic accessory, which can be colour-coordinated with other external parts. In gas airsoft guns it has the same function as in sharp weapons.

What is the function of the foward assist for firearms?

In firearms, it is used to stop the bolt on AR15s in situations where the bolt gets stuck in front of the locking serrations, e.g. due to sand ingress, heavy contamination, etc. After it is jammed, the system is locked and the weapon is fireable. This part of the weapon is encountered in AR15s.
