BCG for a new build

[Mosinwolf762]

On my past builds I have used aero precision M5 BCGs and had very good luck with them. I was shopping around my local gun shop and they are carrying Tacfire BCGs. They are running about 1/2 the price of the aeros so I have my doubts. Does anyone know anything about the brand? Are they any good?

I have not used those before.  I couldn't find out who makes them.  Toolcraft makes a lot of OEM BCGs.  They may even make Aero BCGs.  Here is a link to them.  Armorally is a good company to order from.
