Does this bcg support forward assist?

A

This bolt carrier group does not support a forward assist as it does not have the scallop cuts to catch the forward assist.

Q
SAWYER, guest, from IN, United States, asked on November 08, 2018

Is this 5.56/.223

Featured Answer
A
Answered by War, member, from MO, United States, on November 14, 2018

The 5.56mm and the .233cal are identicle in size and shape. The diffrence is the charge or powder used to expel the projectile. This BCG will fire either.
